摘　　要：采用Handy PEA便携式植物荧光仪对太阳李不同叶位叶片的叶绿素荧光参数进行测定,记录叶绿素荧光诱导动力学曲线的快相部分,绘制太阳李不同叶位叶片叶绿素的OJIP荧光诱导动力学曲线。采用Panton Color Cue-2色差计对太阳李不同叶位叶片色差进行测定。利用分光光度法对太阳李不同叶位叶片叶绿体色素提取液中叶绿素a和叶绿素b的浓度,及其叶绿素总浓度、类胡萝卜素总浓度及花青素苷浓度进行测定。结果表明,随着叶位从梢部向基部降低,叶绿素及花青素含量呈上升趋势,而类胡萝卜素含量则在中间叶位最高。The chlorophyll fluorescence parameters of different position leaves were determined by using Handy PEA, and the fast phase part of chlorophyll fluorescence kinetics curves were recorded to draw OJIP chlorophyll fluorescence induction kinetics curve of the leaf in different blade position. The chroma of different position leaves were determined by using Panton ColorCue-2. Spectrophotometry was used to determine the concentration of chlorophyll a, chlorophyll b, carotenoids and anthocyanins in chloroplast pigment extract. The results showed the content of chlorophyll and anthocyanin rose with the increase of chroma, while carotenoid content in the middle of leaf was the highest.
