桃叶片中花青苷含量与叶绿素含量的相关关系

 测定‘筑波3 号’桃(叶红色) 和山桃(叶绿色) 叶中花青苷和叶绿素含量的结果表明: 随着叶位的升高, 筑波3 号叶中花青苷与叶绿素b 的含量均升高; 而山桃叶中花青苷含量几乎为0 , 叶绿素b含量无变化。叶绿素b 含量与花青苷含量呈极显著正相关(P<0. 001 ) 。测定单位面积叶片紫外光和可见光吸收能力的结果表明, 二者的紫外光吸收能力相近, 而筑波3 号的绿光吸收能力大大强于山桃。

Correlations of Anthocyanins and Chlorophyll in Peach Leaves

The concentrations of anthocyanins and chlorophyll b in the different mature leaves of `Tsukuba 3' and David peach have been investigated. The results showed that, with the elevation of leaf position, in the `Tsukuba 3' peach leaves, anthocyanins and chlorophyll b contents increased. While in David peach leaves, there was very low content of anthocyanins without variation, and the content of Chlorophyll b varied very little. The results of correlation analysis showed that Chlorophyll b content had a remarkable positive correlations with anthocyanins content (P<0.001). The UV and were identified. The results svisible light absorbing capabilities of `Tsukuba 3' and David peach leaves howed that, the UV light absorbability of `Tsukuba 3' peach leaves was similar to that of David peach leaves, but its green light absorbability was much stronger than that of David peach.
