摘要:
本文用分光光度法对紫霞叶片中的叶绿素、类胡萝卜素和花青素含量进行了测定。结果表明,在生长期间叶绿素含量与花青素含量的变化趋势基本一致,类胡萝卜素含量变化不明显;生长初期,叶绿素、类胡萝卜素和花青素含量均为最高,且温度对叶绿素和花青素的合成产生一定的影响,低温条件更有利于叶绿素和花青素的形成。三种色素之间存在显著的正相关,温度与三种色素之间存在负相关关系。

Abstract: In this text, the contents of pigments including chlorophyll, carotenoid and anthocyanin in the leaves of Cotinus coggygria “Zixia” in growing period had been tested by using spectrophotometry. The results showed that during the growth period, the content changing trends of the chlorophyll were consistent with anthocyanin, and the carotenoid was not apparent. At the beginning of growing period, the contents of pigments including chlorophyll, carotenoid and anthocyanin were the highest, and temperature had a certain degree influence on the synthesis of chlorophyll and anthocyanin, the lower temperature was more favorable to the synthesis of chlorophyll and an-thocyanin. There was a significant positive correlation between the three pigment contents, and there was a negative correlation between the temperature and three pigments contents.
