不同象草光合色素及花色苷含量差异分析

Difference analysis of photosynthetic pigments and anthocyanin content in two elephant grasses

为探明不同象草光合色素与花色苷含量差异,本研究以绿叶象草(GXC)和紫叶象草(PXC)为研究材料,采用分光度法对营养期象草的光合色素和花色苷含量进行测定。结果表明:PXC叶片中Chla、Chlb含量均显著高于GXC叶片中的含量,Car含量比GXC叶片中的高11.06%;PXC与GXC不同部位的花色苷含量均呈叶片>叶鞘>皮的分布趋势,且同一部位花色苷的含量PXC均极显著高于GXC。本研究可为饲用象草新品种选育和健康专用饲料的加工提供理论依据。

In order to explore the difference of photosynthetic pigments and anthocyanin content in two elephant grasses,in this study,green leaf elephant grass(GXC) and purple leaf elephant grass(PXC) were used as research materials,and used spectrophotometry to determine the photosynthetic pigments and anthocyanin content in the vegetative stage of elephant grasses.The results showed that:the Chla and Chlb content in PXC leaves were significantly higher than that in GXC leaves,and its Car content was 11.06% higher than that in GXC leaves.The content of anthocyanin in different parts of PXC and GXC was all the same trend:leaves>Leaf sheath>bark.Moreover,the anthocyanin content in same parts of them was that of PXC significantly higher than that of GXC.This study can provide a theoretical basis for the breeding of new varieties of forage elephant grass and the processing of health special feed.
