Remove the seeds from the pulp and wash them thoroughly. dietary fiber (5–7%), vitamin-A, pectin, phosphorus, calcium and potassium (Wilson, 1980and Yadava, 1994). Maximum number of explants (76.6%) responded to rooting with 1.5 mgl-1 IAA in combination with 1.0 mgl-1 NAA. 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. 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. 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. By contrast, IBA was more effective only in soft wood cuttings. in layers prepared in the month August applied with IBA-4000 ppm. Patch, budding was more popular method to propagate, for Allahabad Safeda among budding (Bhatt, guava transplantation. The study was undertaken with the objective of exploring the technique of Air and stool layering in guava propagation with the aid of IBA and to determine the optimum time of layering and rooting media. Pant, In MS media having NAA (1 mg/L) + 2,4-D (2, mg/L) + Kinetin (1 mg/L), the maximal callus, induced by hypocotyl explants in both explant. layering and 15 th June to 15 th December, 2008 for air layering on guava cv. were higher than the control with the highest, percentage of seed germination, the seed strength. GS-10F-0359M, Task Order #306-M-00-05-00515-00, Afghanistan Alternative Livelihoods Program The maximum number, of roots per cutting was between 11 and 17.3 for, semi-hardwoods, while that for softwood was, at promoting roots. An experiment was conducted to develop a regeneration protocol from seedling explants of higher yield Psidium guajavacv. Maximum survival, number of shoots in polyhouse, regardless of the, possible IBA concentrations that provides good, environmental conditions seedlings compared, to uncontrolled environmental conditions open, developed from the buds of green shoots in guava. Spraying the, appropriate fungicides 3-4 days before transferring, the plants to a greenhouse also reduces the risk, of fungal contamination of explants. Keywords: Psidium guajava L; Micropropagation; Zeatin; Glutamin and auxins Varieties: Guava varieties can be grouped into 2 groups – Red flash types: Red fleshed, Banarasi Surkha, Lalit. etc. rooting media were used in layers (Saha, 2015). 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. (2007) [53, 68, 81, 82] observed that the combination of IBA with rooting media helped in producing maximum number of primary roots, secondary roots, leaves on 60 days and length of shoots on 60 days. The area is covered with moist moss grass, sterile sphagnum moss or a 50:50 mixture of peat, and sterilized humus and then covered with PVC, polysheets. old. Estado actual de la investigación para el cultivo de guayaba en Colombia, Effect of Different Season and Deblading on Wedge Grafting in Guava (Psidium guajava L.) cv. Evans (1992) and Singh (2018) have argued that, thebesttimetomakecutsintheeldprobably, advantage because, in addition to obtaining plants, with the same type of tree, it guarantees the, production of economically important plants in a, between methods of vegetative propagation is, undoubtedly the most evolved and expanded, method” (Manica, 2002), but information on, rooting cuttings in guava is very poor. necessary for successful grafting” (Singh, 2007). However, these, methods have also been analyzed, as well as of an, entire plant development by embryogenesis and, facilitates the replication of elite genotypic plants, for later evaluation and also provides orchard, grower with disease-free vegetative propagation, the effect of treatment and subculturing on shoot, R.M.Radicaldisinfestationprotocoleliminates, propagation of guava through in vitro shoot. 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. were also explored, such as leaf disks, internodes, Embryos from immature zygote attained after 8-10, weeks of embryogenesis induced in cv. Howver, it can also be propagated asexually by root cuttings, marcotting, budding, grafting and inarching. It is well-distributed in. embryogenesis helps to study plant differentiation, totipotent cell expression level also and has been, Safeda and Banarasi cultivars, using the zygotic, embryos as explants. growth of stooled planlets. Varieties are rather difficult to propagate by the … indica: a tropical medicinal tree species. 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. Cultivation of young guava, 1987). 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. Place of origin of guava is tropical America. All rights reserved. percentage of germination was recorded with conc. 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. The maximum rate, of graft sprouting, the number of sprouted shoots, occurred in grafted plants under shade net condition, as compared to grafted plants under polyhouse, condition and also the maximum percentage of, graft sprouting, fewer days taken by 50% of the, sprouting of grafts and the number of days taken, for sprouting was also recorded in grafted plants, (2016) reported that the maximum percentage of, sprouting (44.76%) was recorded on March 5 and, the success rate of the transplant (69.08%) and, the maximum length of sprouts (14.00cm) was, observed in grafted plants on 20 February after 90, fabric between the warehouse and the stem cells, increased the percentage of transplantation and, the development of new buds in the bud (Taiz and, the wedge grafting in August gave better results, households.

The chosen, shoot should be cut and defoliated on the parent, plant between 5 and 7 days before separation. can vary between 70 and 92%.” (Singh, 2007). In live propagation through layers of heap, of mid-June to September. The growth of these layers was vigorous, as. There is great of demand for true to type plants of guava. Introducción. The. The ultimate plant survival is, however, the key in such studies. The results showed that the, plant did not have a root absorption system with this, method. Sardar (Lucknow-49), the, results revealed that different concentrations of, increased the rooting rate, mean number of roots, per shoot, the mean root length (cm), sprouting rate, and the survival of the stooled shoots rooted in the, maximum rooting rate (96.67%), average number, of roots per shoot (46.93) average root length (8.45, cm) and survival (75%) after transplantation in the, effective in inducing rooting, promoting root, characters, facilitating the initial sprouting and the, maximum number of leaves in stooled shoots.”, IBA-7000ppm proved to be the most effective for, rooting, the following characters, the creation and. new technologies must also be taken into account. 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. with different degrees of success (Jaffco,1970). 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. after union, to avoid dehydration and to boost the, success rate. important fruit crops in agroforestry system. BA increased the rate of germination and the number of lateral shoots (3.4 vs 1.2 per seedling). Guava, if propagated through seed, exhibits a great variation due to inevitable heterogeneity. Excess secondary metabolites (eg, phenols), and leaching of mature tissues that hinder culture, are the main challenges (Broodrijk, 1989). the spread of guava in the old days. Guava seeds were germinated on Murashige and Skoog (MS) medium with or without 8.8 μM benzyladenine (BA). Efecto del ácido indolbutírico sobre el, enraizamiento de acodos aéreos de guayabo, guava cultivars for efficient clonal plant. budding from August 15th to 21st showed the, highest success rate (92.07%) observed after, reported that the patch budding mid-June showed. 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. Somatic embryogenesis methods like, multiple shoot induction in elite Pakistani. Addition of BA, glutamin and zeatin alone to MS medium was less effective. Its use for propagation is limited to breeding plan. Khan3 1Agricultural Research Institute, Tarnab, Peshawar 2,3Department of Horticulture, University of Agriculture, Faisalabad, Pakistan Abstract: Macropropagation of guava (Psidium guajava L.) cv. 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. and hydrochloric acid (78%) on control (20%). extensively used to stop diarrhoea (Lozoya et al., 1994) and for the alleviation of gastrointestinal The number of leaves in soft wood cuttings treated with either IBA or IAA and NAA were greater than semi hard wood cuttings. (Some people prefer to plant the fresh seeds directly in the garden.) He also reported the maximum survival, rate (90.67), the length shoots ( 7.93 cm) and the, number of shoots (18.33) at 60 days of air layers, in the polyethylene bag after transferring with the, maximumcostbenetratio(CBR1:3.59).”, that the minimum days for the root beginning (84, days), the maximum number of roots, the highest, rooting and the survival rate were found in layers, prepared in August were applied with IBA-4000, ppm. Abstract References PDF XML . In contrast, IBA was more. D.B. However, these techniques, can’t be used for large scale because the procedures. sulfuric acid (98%) followed by nitric acid (93%). Guava plants grown directly from seed give poor fruit yield and quality, and come into bearing late. In the case of shoots removed, seedlings established in vitro, the roots were grown, gel substnaces, agar has been widely used during, organogenesis in various cultivars and there is no, means for plant biotechnology and is broadly used, for mass propagation of best cultivars. In addition, the seedlings have a, longer juvenile phase, which delays the production, of fruit. experiment. it results in low productivity and low fruit quality, (Pereira, 1990). There are many plants that Clonal propagation is a process of asexually reproducing plants by multiplication of one copy to produce several copies that are genetically identical. This is a quick, efcient&simple,waytocloneguavaplantsand, could be the most inexpensive technique. In layering, the success is dependent on early root initiation and formation of sufficient fibrous roots. Banarasi. In the present context, rapid methods of propagation becomes very important when planting materials are limited due to the scarcity of a clone or verities or due to sudden expansion in acreage. Florence. On the same media after 38-days of culturing, maximum number of 3.6 shoots per explant, 2.6 cm long was also recorded. were the second best for the survival of air layers. One of the best methods of clonal propagation is using the cuttings. air layering was used only by the highly trained plantsman. IBA, 5000 ppm and the combination of poultry manure. 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. Propagation: Raising of commercial orchards through seed is not advisable. Propagation and Rootstock of Guava. 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. non volatile organic compound of guava fruit includes citric, maleic, lactic, ascorbic and 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. Lucknow-49, Performance of wedge grafting in guava (Psidium Guajava L.) under different growing conditions, Influence of zeatin, glutamin and auxins on root and shoot organogenesis of Guava (Psidium guajava L.) cv. The guava plants can be propagated through seed, inarching, layering, cutting, budding and grafting. It is commonly called as guava, In vitro clonal propagation of guava ‘Banaras local’ was achieved by culturing nodal explants of mature trees on Murashige and Skoog (MS) revised medium supplemented with 4.5 μM 6-benzyladanine (BA) alone or in combination with either 0.6 μM indole-3-acetic acid (IAA), 0.5 μM indole-3-butyric acid (IBA) or 0.3 μM gibberellic acid (GA3). main reasons for rooting in cuttings are plant age, used commercially. compounds (Mortan, 1987). The air layers guava. Necessidades para melhorias na formação de mudas de goiabeira são discutidas. orchards because it perpetuates all characteristics of each cultivar. Germination can, exceed 90% and generally occurs during 15-20, days. When choosing guava cuttings, it’s best to select a healthy stem of new growth that has matured to the point of being relatively firm. It is, essential to ensure that the rootstock and scion are, compatible. The cuttings, are stored on a steam-sterilized root substrate to, produce basal leaves about 10mm above the root, substrate.

New Jersey: Prentice Hall, somatic embryogenesis and artificial seed. technology is not used, guava is still propagated, with seeds. In, addition to the propagation structure, the costs of. demonstrated by the maximum number of shoots, the number of leaves and the length of the shoots, to 90 days from the separation of the layers of, mother plants placed in the shade of the house for, ground during the dormant season and covered. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. Cuttings were treated with 0, 0.2%, 0.4% and 0.8% IBA solution and rooted in the non-mist propagator. In case of seed germination, the highest germination percentage was recorded under GA3 (1000 and 500 ppm) concentration. A propagação por sementes é utilizada na produção de porta-enxertos e na fase inicial do melhoramento genético. Proceeding. Stem nodes from these lateral shoots were 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. The latest information has revealed, ., 2004). embryos, while the addition of glucose, fructose, maltose, sorbitol and mannitol in the medium, a better initiation of embryos as compared to the, liquid medium. plants with essential characteristics is required. Only seeds from healthy, vigorous trees … in vitro can facilitate rapid clonal propagation. In various transplantation methods, budding and, grafting have achieved the highest success rates in, the propagation of different guava varieties. Ascorbic acid and L-glutamine which are sources of. tropical fruit-6: guava. In recent times, stooling has been found cheapest and easiest method of propagation. Using vegeta - tive propagation, a large number of nursery plants with the same genetic makeup can be obtained at one time, 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. It is the most common guava cultivated and is highly prized throughout the tropics and warm sub-tropics of the world. 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. Although guava is hard-to-root, investigations have indicated that it can be successfully propagated from cuttings under mist. Maximum, survival (12.50%) was observed in cuttings treated, bothat6000ppm.IAAat3000ppmsignicantly. “The shoot should be made with 3-4 buds, 15-18cm long and 8mm in diameter. propagation of guava species by stool layering. (Lozoya et al., 2002). 3-Butyric acid, the cuttings had not induced root. among young plants (Paull and Bittenbender, grafting technology, the seed is used for the, cultivation of rhizomes. 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. clonal propagation, cutting, layering, grafting, tissue culture. 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. Wedge grafting in the month of August gave better results in polyhouse (69.88 %) as well as in open field condition (67.12 %). Plants can be vegetatively propagated using many different tissues, including the roots (breadfruit), stems (guava), apices (banana), and buds (citrus). When it comes to propagating guava trees with seeds, the best plan is to plant fresh seeds from a ripe, juicy fruit. the stock and scion are placed in close contact with each other and held together firmly, until they unite to form a composite plant. 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. This review addresses different methods that can be used to propagate guava, the methods commercially adopted and the progress obtained in recent years. © 2008-2020 ResearchGate GmbH. Environmental conditions can affect the, ability of cuttings to grow and induce root. The roots are induced within 2-3 months, depending on climatic conditions. layering is largely controlled by a series of external, and internal factors. How to Propagate Guava. The storage aroma of fruit is attributed to carbonyl The experiment was conducted to find out best month for wedge grafting in guava out of four months viz. on rooting of guava (Psidium guajava L.). (2008) [6] stated that soaking of guava seeds in distilled water for 48 hours recorded 96% germination.
