Abstract

GAD activity and gamma-ABA content of wheat embryos at 7 ripening stages were verified with the aim of studying the metabolic activity of embryo during dehydration and quiescence of caryopsis. Data showed that in the early stage of ripening GAD activity is very low, increases rapidly at dough-stage, remaining constant up to waxy-stage, and decreases in the last fully-ripe embryos. gamma-ABA content appears to be roughly parallel to the variations of GAD activity.

摘要

为了研究颖果脱水和休眠期间胚的代谢活性，对7个成熟阶段小麦胚的谷氨酸脱羧酶（GAD）活性和γ-ABA含量进行了测定。数据表明，在成熟早期GAD活性非常低，在面团期迅速增加，直至蜡熟期保持恒定，而在最后完全成熟的胚中下降。γ-ABA含量的变化似乎与GAD活性的变化大致平行。
