in vitro propagation of caprifig and female fig varieties (ficus carica l.) from shoot-tips
fig trees are threatened by the attack of fig mosaic disease (fmd) on leaves and fruits caused by viruses of several genera. shoot-tip culture is a convenient method for viral sanitation. for this purpose, a reliable protocol for rapid in vitro propagation was developed with shoot-tips of three major tunisian local fig (ficus carica l.) varieties zidi (zdi), soltani (sni), bither abiadh (ba) an...
متن کاملStudy of factors affecting direct shoot regeneration of pear (Pyrus communis L.)
Conventional methods of pear breeding, largely based on intra- and inter-specific hybridization, are difficult because pear is highly heterozygous, polygenic and has a long juvenile period. Genetic improvements of pear cultivars are possible through induction of mutations and gene transfer by genetic engineering. A general prerequisite for these approaches is to establish an efficient plant reg...
متن کاملIN VITRO PROPAGATION OF POINTED GOURD (Trichosanthes dioica Roxb.) THROUGH ENCAPSULATED SHOOT TIPS
Plants were regenerated from encapsulated shoot tips of pointed gourd. Shoot tips isolated from multiple shoot cultures of AM-8 and AM-15 cultivars of pointed gourd were encapsulated in sodium alginate beads. For germination and shoot proliferation, encapsulated shoot tips (artificial seed) were cultured in MS basal medium containing different concentrations and combinations of BAP and NAA. Use...
متن کاملIn Vitro Response of Encapsulated Shoot Tips of Spilanthes Acmella
Multiple shoots were achieved through axillary bud explant of Spilanthes acmella on MS medium supplemented with 0.5mg/l BA. In vitro developed axillary buds and tiny shoots isolated from the multiple shoots were encapsulated in different strength of sodium alginate. The present work explains the role of components of culture medium on morphogenic response of encapsulated shoot tips to various t...
متن کاملin vitro establishment and clonal propagation of sebri pear cultivar
two experiments were performed for in vitro establishment, proliferation and shoot growth in axillary bud explants of sebri pear cultivar. in the first experiment, the effect of different concentrations of iba(indole-3-butyric acid) on explants’ establishment was evaluated. in a second experiment, the influence of several combinations of pgrs (plant growth regulators)on shoot proliferation and ...
