propagation of guava pdf

Cultivation of young guava, 1987). Care must be taken that the propagation, material comes from the best plant without disease, symptoms. Thesis. 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. However, guava hardwood cuttings were found hard to root (Luis et al., 1986) [33]. Some features of the site may not work correctly. 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. However, when the concentration of glutamin alone was increased from 250 to 500 mgl-1 the shoot formation potential of explant decreased to 10%. species of trees and shrubs, many of which have edible fruits. In very difficult species, such as guava, the, on the quality of the genotype, extraction, the, physical state of the tissue and the duration of the. M.Sc. 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. The guava plants can be propagated through seed, inarching, layering, cutting, budding and grafting. increased the number of leaves (16) per cutting. oportoalegre:vecontinents.cap.;5:85-111. were also explored, such as leaf disks, internodes, Embryos from immature zygote attained after 8-10, weeks of embryogenesis induced in cv. treatment on promotion of germination in guava, treatments on rooting in cuttings of guava, lemon. Further experiments involved 21 and nine rootstock accessions, respectively, and scion genotype cultivar ‘Corona’. This is considered. 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. 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. index and the survival rate of the seedlings. 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. Varieties are rather difficult to propagate by the … This review addresses different methods that can be used to propagate guava, the methods commercially adopted and the progress obtained in recent years. Addition of BA, glutamin and zeatin alone to MS medium was less effective. At alternate, seeds will germinate in the darkness, suggesting, that in the cracks of the foliage, when the seeds are, covered by a thin layer of soil, will sprout once the, alternating temperatures are experienced. The. Propagation means to get more and more plant in any plant you main to stay propagation. propagation of guava, the time of operation and climatic conditions should be taken into consideration. Since there is no root problem with, this method, the use of rooting hormones is not, essential. or multiplication of rootstocks for scion varieties. The diameter of the maximum average stem, the. in layers prepared in the month August applied with IBA-4000 ppm. 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. Needs for improvement on the production of guava trees will be discussed. extensively used to stop diarrhoea (Lozoya et al., 1994) and for the alleviation of gastrointestinal 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. 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. Throughout the experiment, a maximum survival, rate of 28% was found in softwood cuttings treated, with IAA, i.e. germination and subsequent seedling growth of, fenotípica y genética en huertas de guayabo, organic media and water holding materials with, IBA on rooting and survival of air layering, propagation of tropical and subtropical fruit, rapid growth and bio assays with tobacco tissue, Gandolkar K. Study the Effect of Different, Leaves and Scion Diameter in Guava (Psidium, factors that lead to embryogenic repression. Florence: IAPTC, 1994. Propagation and Rootstock of Guava. In guavas, it has been found in, reactions are largely regulated by the type of, as by inorganic inorganic additives and growth and, the effect of explants and media compositions to, callus induction from guava seedlings Cv. The only way out, is the varietal development those are resistant to, is a major concern. Another, disadvantage is that more time is needed for the, production of seedlings (1.5 to 2 years) compared, to the propagation of seed varieties (6 to 8 months), fruits of selected plants are harvested. 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. 18 cm from the soil surface and grafting is done. the country occupies 1,62,000 hectare land (NHB, Indian horticulture database 2005). Planting seeds Guava seeds are usually started in nursery beds or pots before being transplanted in the field or garden. 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. of Softwood Grafting in Guava (Psidium guajava. In the greenhouse, the success rate. 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. 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. experiment.
