大麦发芽过程中内源激素的变化

摘要

The change rules of GA3,IAA and ABA content of two kinds of barley including imported Gairdner and domestic Ganpi No.2 in malting process was analyzed. The results showed that the curve of GA3, IAA and ABA content of both two kinds of barley during malting process waved with the malting time, and the change rules of their endogenous hormone were almost the same. Meanwhile, it was found that GA3 plays an important role to stimulate the secretion of LAA and ABA in the process of malting.%选用进口大麦Gairdner和国产大麦甘啤二号为原料，分析比较了发芽过程中赤霉素、生长素和脱落酸等内源激素含量的变化规律。研究结果表明，3种激素在两种大麦发芽过程中均呈现出随发芽时间上下波动的趋势，且两种大麦在发芽过程中各激素含量的变化规律基本一致。同时，赤霉素均有刺激并诱导其他两种内源激素的作用。
