Seedling-derived cotyledon explants of squash (Cucurbita pepo L.) of commercial cultivars True French, Ma'yan and Goldy were regenerated in vitro on Murashige and Skoog medium augmented with 1 mg/l benzyladenine. After 4 weeks in culture small shoots and buds regenerated only on the most proximal cotyledon edge. Culture on an elongation medium with a(More)
Ultrasonic treatment (0.5–2 min) stimulated multiple shoot regeneration to high levels in vitro from recalcitrant cotyledon explants of commercial squash (Cucurbita pepo L.) cultivars Ma’yan and Bareqet, on Murashige and Skoog [Physiol Plant 15:473–497, 1962] (regeneration) medium augmented with 4.4 μM benzyladenine. At this stage, unsonicated control(More)
