Keep reading to learn more about guava cutting propagation and growing guava trees from cuttings. Fracaro, 2004 found, the primary roots had, sufcientnumbers,adistributedaroundthe, suitable growth and high branching, providing, exploration of large volumes of soil in search of, early beginning of the root and on the formation, layering is commonly adopted viz Air layering and. There is great of demand for true to type plants of guava. productivity is not recommended (Pereira, 1990). This review article deals with various methods used in the propagation of guava, which are commercially adopted, and the recent progress and trends related to it. oportoalegre:vecontinents.cap.;5:85-111. and quality with special reference to São Paulo, growth regulators and types of cuttings on rooting, ABA and sucrose on germination of encapsulated, of method and time of propagation in guava, of IBA concentrations on guava stooling and, plantlets survival under open and polyhouse. technology is not used, guava is still propagated, with seeds. the family Myrtaceae, which comprises 3,000, species under 80 genera. sulfuric acid (98%) followed by nitric acid (93%). Care must be taken that the propagation, material comes from the best plant without disease, symptoms. Growth regulator like IBA has been used to stimulate plant growth and specially root formation with better vigour in layering. Therefore, the use of seeds is recommended, only in breeding programs where variability among. rooting media were used in layers (Saha, 2015). Propagation and Rootstock of Guava. and sometimes in guava also. However, when the concentration of glutamin alone was increased from 250 to 500 mgl-1 the shoot formation potential of explant decreased to 10%. or multiplication of rootstocks for scion varieties. In vitro shoot proliferation and propagation of guava (Psidium guajava L.) from germinated seedlings A preview of the PDF is not available. The asexual methods for propagation are used to clone chosen genotypes of breeding methods and to establish commercial fruit orchards, as they provide all the distinctiveness of each cultivar. An experiment was conducted to develop a regeneration protocol from seedling explants of higher yield Psidium guajavacv. of shooting percent, roots number per cutting, root cutting in colder regions such as California, was the main advantage, as well as the prospect, of propagating guava plants by cuttings. It can be, done by inarching in guava. Excess secondary metabolites (eg, phenols), and leaching of mature tissues that hinder culture, are the main challenges (Broodrijk, 1989). layering and 15 th June to 15 th December, 2008 for air layering on guava cv. Banarasi. The storage aroma of fruit is attributed to carbonyl 18 cm from the soil surface and grafting is done. can vary between 70 and 92%.” (Singh, 2007). In vitro propagation of guava (Psidium guajava L.) shoots by direct organogenesis is an alternative to quickly obtain productive plants. seedlings (5 mm in diameter) have been tried, such as Forkert, shield, patch, chip, etc. There are several propagation technologies available, however, the adoption levels are rather different between producing countries. Howver, it can also be propagated asexually by root cuttings, marcotting, budding, grafting and inarching. The predominant Subsequently, inarching or budding (patch or shield) can be done for propagation. commercial use are normally considered waste. Seedlings are ready for field transplanting or used as rootstocks when they are six months to one year old. For air layering the operation was done in 3 months i.e. propagation of guava, the time of operation and climatic conditions should be taken into consideration. in layers prepared in the month August applied with IBA-4000 ppm. Maximum, survival (12.50%) was observed in cuttings treated, bothat6000ppm.IAAat3000ppmsignicantly. Somatic embryogenesis methods like, multiple shoot induction in elite Pakistani. The maximum number of leaves (8) was recorded in soft wood cuttings treated with IBA. The experiment was conducted to find out best month for wedge grafting in guava out of four months viz. Maximum explants showing shoot response (48%) was observed on MS-medium supplemented with 6-benzyladanin (BA) 1.0 mgl-1combined with 0.5 mgl-1ziatin. As compared to control, auxin treatment promoted rooting in both types of cuttings. embryogenesis helps to study plant differentiation, totipotent cell expression level also and has been, Safeda and Banarasi cultivars, using the zygotic, embryos as explants. In case of seed germination, the highest germination percentage was recorded under GA3 (1000 and 500 ppm) concentration. Because, of the intense cold that caused the freezing and, death of trees in orchards, it was likely to use new, shoots from the root system to propagate new, plant without a graft because the root system is, genetically identical to the stem. Cuttings were treated with 0, 0.2%, 0.4% and 0.8% IBA solution and rooted in the non-mist propagator. During winter cultivation the rootstocks cultivars ‘Renova’ and ‘Esvier’ significantly promoted vegetative growth of the scion and rootstock Code E induced a significantly higher fruit yield than the standard rootstock ‘Corona’. Auxin is relatively helpful among cuttings to overcome difficulties in root induction. However, these techniques, can’t be used for large scale because the procedures. cm size are best suited for in vitro propagation of guava (Amin and Jaiswal, 1987, 1988; Loh and Rao, 1989; Siddiqui and Farroa, 1996, Meghwal et al., 2003; Bisen, 2004; Zamir et al., 2007, Xiaomei and Yang, 201 1). Agrawal S. Effect on rooting in Guava cv. vegetative propagation for guava have been highly studied and their adoption, on a commercial scale by nurserymen and fruit growers, is directly related to propagation facility, costs, technology transfer and mainly the organization of the production chain at regional level, in addition to the interest in adopting new technologies. It is, essential to ensure that the rootstock and scion are, compatible. Needs for improvement on the production of guava trees will be discussed. Student, Lovely Professional University, . La guayaba (Psidium guajava L.) es considerada una fruta de importancia comercial en más de sesenta países, la cual se utiliza en la agroindustria y consumo en fresco, debido a sus propiedades nutraceúticas, ya que se considera una fuente importante de vitamina C, mejorando así la salud de los consumidores. by stem cutting collected from mature stockplants. A, different growth regulators and types of cuttings. species of trees and shrubs, many of which have edible fruits. Sunderland. (Some people prefer to plant the fresh seeds directly in the garden.) The highest number of roots (23.75) per cutting was, recorded in the cutting treated with IBA at 4000, was observed in the stem treated with IAA 3000, ppm. Safeda. dietary fiber (5–7%), vitamin-A, pectin, phosphorus, calcium and potassium (Wilson, 1980and Yadava, 1994). Explants from other sources. and quality (Dhua and Sen, 1984). The rootstock stem is separated between 15 to. rootstock may be grafted and diameter of about 5, -7mm. in guava. The ultimate plant survival is, however, the key in such studies. medium and rooting (Hartman and Kester, 2002). Using vegeta - tive propagation, a large number of nursery plants with the same genetic makeup can be obtained at one time, Environmental conditions can affect the, ability of cuttings to grow and induce root. Guava plants grown directly from seed give poor fruit yield and quality, and come into bearing late. Triazole mediated somatic embryogenesis, production manual. using leaf disc as explant in guava cultivars. Psidium guajava L. through cuttings. extensively used to stop diarrhoea (Lozoya et al., 1994) and for the alleviation of gastrointestinal on rooting of guava (Psidium guajava L.). On MS containing combination of BA (2.0 mgl-1) and zeatin (1.0 mgl-1), 37% explants responded which produced 2.3 shoot per explant after 42 days of culturing. Ascorbic acid and L-glutamine which are sources of. Propagation by seed is used for rootstock production and for raising populations for screening at early phases in the breeding programs. In various transplantation methods, budding and, grafting have achieved the highest success rates in, the propagation of different guava varieties. the country occupies 1,62,000 hectare land (NHB, Indian horticulture database 2005). This is considered. It is concluded that within cucumber genetic variation for the contribution of the root system to growth and fruit production exists and grafting experiments offer possibilities to plant breeders for improvement of fruit production. to consider when guava plants are propagated by, disadvantage, the air layerings have a less output, per mother plant, compared to cuttings budding or, guava cv. Diversas são as tecnologias de propagação disponíveis; entretanto, os níveis de adoção são bastante diferentes entre os países produtores. J.2009. (Lozoya et al., 2002). 3-Butyric acid, the cuttings had not induced root. Comparatively IAA was stronger than IBA in sprouting for both types of cuttings. Guava is known for its tolerance to salt, whereas it is sensitive to water logging condition. One of the best methods of clonal propagation is using the cuttings. Keywords: Psidium guajava L; Micropropagation; Zeatin; Glutamin and auxins Cutting with root promoters, (synthetic auxines such as indolic butyric acid, (IBA) or naphthalene acetic acid (NAA)) treatments, and stored in pot in mist diffusion system, with a, normal water jet (intervals of 5 seconds at every, 5 minutes). respect to growth and production. growth of stooled planlets. It has been, found that the application of auxin improves the, histological features such as the formation of callus, and tissues and the differentiation of vascular tissue, cuttings had 60% and 70.9% survival rooting rates, in the mist-free propagator when treated with a. Singh et al. The use of growth regulators to increase rooting and survival percentage of guava cuttings had limited success (Wally et al., 1981) . The use of, 5-10% sodium hypochlorite, followed by 0.5%, to 1.0% mercury chloride, reduced the microbial, contamination of explants from mature woody, respond better to the plant than mature trees (Shah, from differentiated tissues or callus or is called, organogenesis. Although guava is hard-to-root, investigations have indicated that it can be successfully propagated from cuttings under mist. and pulmonary disease in Bolivia and Egypt (Batick, 1984). percentage of germination was recorded with conc. mg per 100gm of fruit (Campbell, 1984; Menzel, 1985; Martin et al., 1987) and abundant in nitrogen actually induced somatic embryogenesis, while PEG and L-proline accelerated the maturity, the different sources of carbon, 5-6% sucrose, was better for inducing and maturing of somatic. Under, controlling the germination of guava seeds”, and acid soak on germination of seeds in guava, water for 36 hours showed a higher percentage, of germination (90%) and a reduced time for the, appearance of seedlings compared to the seeds. After about three months, the cutting, by the young and juvenile branches offers a better, Safeda discovered that the auxin had no effect on, the number of days for outbreaks of buds, while, at 1000 and 3000 ppm and NAA at 2000 ppm are, 79.84, 75.96 and 76.59% respectively. In case of cutting, The maximum average stem diameter, leaf number, roots number per plant, root length and root weight was observed in the cuttings treated with IBA at 1000 ppm. “The shoot should be made with 3-4 buds, 15-18cm long and 8mm in diameter. Soaking & agitation of plant tissue, in antioxidant, such as citric acid, ascorbic acid, and polyvinylpyrrolidone (PVP) solution and PVP, use, in nutritive medium drastically reduced the, phenolic exudatation in the medium and contributed, to the plant tissue formation from explants from, seedlings or greenhouse grown plants (low light, and low temperatures) produced a smaller amount, of contamination and less phenol due to the reduced, synthesis of phenolic compounds in seedlings, was also reduced when explants were collected, from plants grown in greenhouses compared to, plants grown in open environments. New Jersey: Prentice Hall, somatic embryogenesis and artificial seed. Available via license: CC BY-NC 4.0. Research Article : A Break Through in Guava (Psidium guajava L.) Propagation from Cutting. of grafting time and environment on the graft, success of guava (Psidium guajava L.) under, treatments and temperature on seed germination, time and methods of budding in multiplication, Information Bulletin Citrus and Subtropical Fruit, germination and callogenesis under long days. This technique can, produce up to 95% of success, but more laborious as, compare to cutting or layering. Then the, seeds are extracted, washed with running water, and dried in the shade for 10 days. Guava (Psidium guajava L.) can be propagated by seed, layering, air layering, grafting (budding or grafting), cuttings (root or shoot) or tissue culture. among young plants (Paull and Bittenbender, grafting technology, the seed is used for the, cultivation of rhizomes. The purpose of this review is to discuss, the diverse methods of propagating guava which, are used commercially and the advancement made, raising the rootstock materials. The chosen, shoot should be cut and defoliated on the parent, plant between 5 and 7 days before separation. “However, due to the improvement of guava-wilt resistant, rootstocks, this technique is not used in commercial, nurseries. Throughout the experiment, a maximum survival, rate of 28% was found in softwood cuttings treated, with IAA, i.e. (2008)  stated that soaking of guava seeds in distilled water for 48 hours recorded 96% germination. Cultivation of young guava, 1987). It is well-distributed in. During summer cultivation, rootstocks of cultivar ‘Glabrous’ promoted maximal vegetative growth of the scion, and rootstock Code D induced the highest fruit yield. The maximum number, of roots per cutting was between 11 and 17.3 for, semi-hardwoods, while that for softwood was, at promoting roots. increased the number of leaves (16) per cutting. The various propagation techniques are available, but. In recent times, stooling has been found cheapest and easiest method of propagation. Content may be subject to copyright. Therefore, seed multiplication, will result in genetic heterogeneity that can be, observed in orchards and plants in the same orchard, propagation in commercial orchards to increase. Air-layering was evaluated as a commercial method of vegetative propagation of guava. ultimate survival of plants is the key to such studies. Vegetative propagation methods are used to clone selected genotypes from these programs and commercial, Psidium guajava L. belongs to family Myrtaceae which comprises approximately 150 Detection of growth, regulators, information on role of the juvenile, stage in reproduction, advances in knowledge of, chimeras, micro-propagation and application of, vegetative propagation to prevent diseases caused, by viruses and other pathogens (Preece, 2003, 2001), stoolings (Pathak and Saroj, 1988) and, inarching (Mukherjee and Majumder, 1983) are not, yet commercially feasible due to different success, rates, the lack of a tap root system and burdensome, processes. The cutting treated with IAA and IBA, weight and 16.62g and 16.25g respectively.”, compared with the control, auxin treatment favored, rooting in both cuttings. Khan3 1Agricultural Research Institute, Tarnab, Peshawar 2,3Department of Horticulture, University of Agriculture, Faisalabad, Pakistan Abstract: Macropropagation of guava (Psidium guajava L.) cv. The various propagation techniques are available, but the levels of adoption are quite different in guava producing areas. The propagation of the guava (Psidium guajava L.) may be carried out with seeds, layering, grafting or budding, cuttings (roots or shoots) or by micropropagation. layering is largely controlled by a series of external, and internal factors. “Sprouting begins between 9 and 12, days after transplantation and the polyethylene, is removed. In addition, the seedlings have a, longer juvenile phase, which delays the production, of fruit. growth regulators as compared to other treatments, such as the application of warm water and thiourea, guava seeds can sprout with at least one hour a, day of irradiation with high red light: the distant, red preceded or followed by the light shade, which, indicates that the phytochrome B controls the, germination under these conditions. “Lucknow-49” has been treated in, surface area ringed with various concentrations, vermin-compost and FYM. Serial minicutting technique for guava 'Paluma' propagation.pdf. main reasons for rooting in cuttings are plant age, used commercially. D.B. 100 mg per 100 g of talc.”, IBA (4000ppm) showed maximum results in terms. The latest information has revealed, ., 2004). Guava propagation through seed does not produce true-to-type plants while clonal propagation has assured true-to-type plants. Pergamon Press, Oxford – London, N.Y, apartirdeestaquiaherbácea.RevistaBrasileira. The most suitable period for conducting, girdled area must be selected. Evaluación preliminar, View 2 excerpts, references results and background, By clicking accept or continuing to use the site, you agree to the terms outlined in our. Determinar el estado actual de la investigación para el cultivo de la guayaba en Colombia. One can use stem of all kinds to make. Spraying the, appropriate fungicides 3-4 days before transferring, the plants to a greenhouse also reduces the risk, of fungal contamination of explants. Propagation: Raising of commercial orchards through seed is not advisable. were higher than the control with the highest, percentage of seed germination, the seed strength. Germination of seeds was improved, . CambridgeUniversityPress,2006;p.541-549. Maximum number of explants (76.6%) responded to rooting with 1.5 mgl-1 IAA in combination with 1.0 mgl-1 NAA. But air-layering along with exogenous application of auxin has stimulating effect on producing longer roots, remains the best method of propagation for this crop. alteration for stress tolerance, genomics use, molecular physiology and bioinformatics can be, used to understand plant physiology in plants better, with changing weather conditions and development, sources has been hampered by higher microbial, contamination and exudation of the phenols at, higher level from plant tissues will resulting in the, removal of the darkness and recalcitrant nature of, plant tissues. In live propagation through layers of heap, of mid-June to September. Propagation means to get more and more plant in any plant you main to stay propagation. Cuttings must have three internodes and four nodes. This is a quick, efcient&simple,waytocloneguavaplantsand, could be the most inexpensive technique. Early sprouting (7.90, days), maximum rooting rate (90.73%), maximum, number of secondary roots (30.82), more leaves, 45 days after transferring into bags of polyethylene, shoots of guava cv. http://dx.doi.org/10.19045/bspab.2017.60014, An experiment was conducted to investigate the effect of different auxin on rooting in soft and semi-hard wood stem cuttings of guava. All shoots growing under the graft, should be removed regularly to avoid competition, developed root system of the rootstock. necessary for successful grafting” (Singh, 2007). plants with essential characteristics is required. In this situation there is, a genetic variability in root systems, in particular, there is a variation in the strength. Red fleshed fruit contains 3 mg of carotene/100 g of fruit. The disadvantage is. Florence: IAPTC, 1994. July (M1), August (M2), September (M3) and October (M4) under two different growing conditions (polyhouse condition and open field). experiment. The air layers guava. Cayo District: Horticulture, regulators on rooting of soft wood cuttings of, and non-auxinic chemicals on root initiation of, air-layers of jackfruit (Artocarpus heterophyllus, 2nd Ed. In overall experiment, maximum of 28% survival rate was recorded in soft wood cuttings when exposed to IAA at 100 mg per 100 g talcum powder combination. In the greenhouse, the success rate. Therefore, First, the soil fungus caused guava wilt disease to, a damaging effect. completely covered with a biodegradable material: leaf and have about 6 to 8 hard leaf buds, the leaf, can be removed. Vegetative propagation of guava through softwood cuttings is excellent for nursery plants production because it is cheap, fast and economical clonal propagation method . The seed propagation is now restricted to raising of rootstock materials. The roots are cut about 0.5-1, m from the trunk of a mature tree.” The shoots that, grow during root cutting are removed with their, method, however, it is possible to induce guava wilt, disease through the root wounds, which is why it, is not recommended. Some features of the site may not work correctly. Banuprakash et al. The maximum number of roots (27.6) per cutting was recorded in soft wood cuttings treated with IAA. Biotechnology of perennial fruit crops. Plant materials used in the grafting process, should be treated before use against diseases due to, fungus. in vitro can facilitate rapid clonal propagation. Explants taken from 49-day old seedlings were cultured on MS-medium modified with different concentration of plant growth regulators. Singh, with rooting media helped produce the maximum, number of primary roots, secondary roots, leaves, in 60 days and length of shoots in 60 days. How to Propagate Guava Cuttings. Its use for propagation is limited to breeding plan. Guava seeds were germinated on Murashige and Skoog (MS) medium with or without 8.8 μM benzyladenine (BA). Propagation – guava is commonly multiplied by seeds. proliferation on nodal explants of mature trees. T-budding, T-grafting and cleft grafting. mixture of 2,4-D and other auxin or cytokinins. Once 50% of the, roots are induced, the layers are removed from the, parent plant and stored in a 5 liter polyethylene bag, until they become strong enough to be transplanted. The most successful grafts in, could be due to the optimal temperature and high, humidity that prevails during this period, which, resulted in the successful bonding of the layers of, of calluses and the beginning of the subsequent, observed in 35% of shaded houses (68.80 and, 87.19% respectively), followed by a 50% shaded, case (58.00 and 79.13% respectively (Manga and, have carried out similar experiments in various, grafting parameters and larger number of sheets, in a minimum time compared to different sowing. Clonal propagation is a process of asexually reproducing plants by multiplication of one copy to produce several copies that are genetically identical. The guava propagation by seeds is carried out for the growing rootstocks and for growing plants to be detected in the early stages of the cultivation of guava trees. No interaction was found between scion and rootstock effects with, Guava can be propagated by air-layering, ground layering, inarching, root and shoot cutting and budding. The minimum days for root initiation (84 days), maximum number of roots, higher rooting and survival percentage, Guava (Psidium guajava L.) can be propagated by seed, layering, air layering, grafting (budding or grafting), cuttings (root or shoot) or tissue culture. Malik2 and M.A. Introducción. Guava is propagated through budding (Gupta and Mehrotra, 1985; Kaundal et al., 1987) [14, 29] , air layering (Singh and Singh, 1970; Sharma et al., 1978; Manna et al., 2001) [67, 63] , stooling (Pathak and Saroj, 1988)  and inarching (Mukherjee and Majumder, 1983)  these are still not commercially viable due to varying rate of success, absence of tap root system and cumbersome process. Polyhouse condition gave better response than open field condition with respect to number of days taken to sprouting, graft-take per cent, sprouting per cent, number of leaves per new shoot, height of graft, girth of graft and graft survival percentage. The asexual methods for propagation, are used to clone chosen genotypes of breeding methods and to establish commercial fruit, orchards, as they provide all the distinctiveness of each cultivar, various methods used in the propagation of guava, which are commercially adopted, and the, recent progress and trends related to it. sinauer associate Inc publishers. In, addition to the propagation structure, the costs of. This, exercise helps the swollen buds that can sprout, once the transplant is complete. Os métodos de propagação vegetativa são utilizados para clonar os genótipos selecionados nas fases mais adiantadas dos programas de melhoramento genético e nos plantios comerciais, pois perpetua todas as características das cultivares de interesse. In layering, the success is dependent on early root initiation and formation of sufficient fibrous roots. ABSTRACT: The propagation of the guava (Psidium guajava L.) may be carried out with seeds, layering, grafting or budding, cuttings (roots or shoots) or by micropropagation. Remove the seeds from the pulp and wash them thoroughly. Evans, (1992)  and Singh (2018) [76, 77] contended that probably the best time to take cuttings from the field is at the beginning of the rainy season. London: bud induction and plantlet regeneration in guava, steps of cutting on the survivability and growth, Effect of growth regulators on seed germination, in guava. Stooled Shoots Of Guava (Psidium Guajava L.), Study the suitable period of wedge grafting in, guava under different condition of Chitrakoot, vitro multiplication and conservation of Garcinia.

Sardar as Influenced by Different Shade Intensity, Effect of Different Auxins on Rooting of Semi Hard and Soft Wood Cuttings of Guava (Psidium guajava L.) CV. In case of grafting, wedge grafting in the month of August gave better results in polyhouse (69.88 %) as well as in open field condition (67.12 %). Australian Journal of Crop Science, Lismore. with different degrees of success (Jaffco,1970). Plants can be vegetatively propagated using many different tissues, including the roots (breadfruit), stems (guava), apices (banana), and buds (citrus). fruit is an excellent source of vitamin-C (Rathore, 1976; Yadava, 1994), which is upto 2000 Guava, if propagated through seed, exhibits a great variation due to inevitable heterogeneity. Introduction Guava (Psidium guajava L.) belong to family Myrtaceae. a better response to the number of sprouting (7.49), percentage of survival (73.33%), average length of, the shoot (50.27 cm), average leaf length in new, growth (6.67 cm), average leaf width (3.71 cm), out instantaneously prior to or during the growth, period.
