【摘要】 通过对各种氨基酸的分析,认为SER、MET、ILE三种氨基酸对雷竹林出笋有一定的作用;笋芽的不同发育阶段的氨基酸含量是不一样的,随着发育阶段的前进,氨基酸含量也上升;从植株年龄看来,出笋林分与未出笋林分的氨基酸总量没有明显区别,这说叫雷竹林在秋季出笋与未出笋与植株年龄关系不大;通过对内源激素的分析,认为笋芽的萌发主要是由GA3/ABA的值来调控的;通过对营养成分的分析认为竹林中增施N肥有利于出笋。
【Abstract】 Analyzing the content of amino-acid, the results shown that SER, MET and TLE were effect on bamboo shoot pullulation; the content of amino-acid in buds was ascending with progressing of development stage. TAA of shoot pullulation and non-pullation porest was much the same in different age bamboo, so shoot pullulation or non-pullulation had not relation to the age of bamboo. By analyzing the endogenous hormones, the results showm that bud germination was controlled by GA3/ABA. In addition, applying nitrogen fertilizer properly was good at shoot pullulation.
