Abstract: | Summary Somatic embryo formation occurred from immature zygotic embryos within ovules of stenospermocarpic seedless grapes (Vitis vinifera L.), when cultured for two months on liquid Emershad/Ramming medium. Somatic embryos continued to proliferate after excision and transfer to Emershad/Ramming medium supplemented with 1 M benzylaminopurine and 0.65% TC agar. Plant development from somatic embryos was influenced by genotype, medium, phase (liquid, agar), stage (torpedo, mature) and their interactions. Optimal plant development occurred on Woody Plant Medium supplemented with 1.5% sucrose + 1 M benzylaminopurine + 0.3% activated charcoal and 0.65% TC agar.Abbreviations ABA abscisic acid - BAP benzylaminopurine - ER Emershad/Ramming - GLM general linear model - MGLH multivariate general linear hypothesis - MS Murashige/Skoog - NaClO sodium hypochlorite - TC tissue culture - WP woody plant |
