Endogenous gibberellin (GA)-like substances were examined in suspension cultures of somatic embryos of a hybrid grape (Vitis vinifera x Vitis rupestris) during embryogenesis, and in mature embryos chilled at 4 degrees C, and subsequently incubated at 26 degrees C with and without abscisic acid (ABA). The extract was separated into a nonpolar fraction (would contain GA-precursors); a fraction that would contain free GAs; and a highly H(2)O-soluble fraction (would contain GA glucosyl conjugates… CONTINUE READING
