对6种不同变异类型毛竹叶片中的叶绿素、游离氨基酸、β-胡萝卜素含量及硝酸还原酶活性这4个生理指标进行了测定。结果表明:叶绿素含量、β-胡萝卜素含量、游离氨基酸含量和硝酸还原酶活性这4个生理指标相互之间呈极显著正相关；各指标年变化呈单峰曲线，达到峰值的时间是在8～9月份；与普通毛竹类似的株型较大的花毛竹、厚壁毛竹和曲杆毛竹，其生理指标数值比株型较小的龟甲竹、绿槽毛竹和圣音竹大，且达到最高峰的时间要早30d。

Chlorophyll,free amino acid,β-carotene content and nitric acid reducing agent activity of 6 different variation type bamboo＇s leaves were measured.The results show that chlorophyll,free amino acid,β-carotene contents,nitric acid reducing agent activity were extremely-significant and positively correlated with each other;each index variation presented a single peak curve,the time of the peak were in August and September;the physiological indexes values of flower bamboo,thick wall bamboo and curved rod bamboo that have bigger tree type were la...
