Abstract: Influence of industrial waste water of Kunming Smeltery and Hongwei Paper Mill on chlorophyll a and b,β-carotene, and xanthophyll centents in Hydrilla verticillata L. was studied.The experiments showed that four pigments in different solutions of both waste water diluted are lower than those of the control. Chlorophyll a and b,andβ-carotene contents in the waste water of Kunming smeltery are much lower than those in the waste water of Hongwei Paper Mill, but the response of xanthophyll on both waste water is contrary.

Key words: Influence photosynthetic verticillatal

摘要： 研究了昆明冶炼厂污水和红卫造纸厂洗浆污水对黑藻（Hydrilla verticillata L．）叶绿tab，β-胡萝卜素和叶黄素含量的影响。试验表明在不同稀释倍数的两种污水中，四种色素都低于对照．昆明冶炼厂废水比红卫造纸厂洗浆污水使叶绿素a和b，以及 β-胡萝卜素含量降低更多，叶黄素对两种污水的反应却相反。
