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 μM 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 μM benzylaminopurine + 0.3% activated charcoal and 0.65% TC agar.
