| 摘 要： | 以叉鞭金藻和三角褐指藻为材料，采用室内一次性培养的方法研究了UV－B辐射对光合色素（叶绿素a和类胡萝卜素）含量的影响，结果显示，低剂量的UV－B辐射处理对叉鞭金藻的光合色素含量影响不明显，甚至可使光合色素的含量升高；而高剂量的UV－B辐射处理引起叉鞭金藻光合色素含量降低，三角褐指藻的叶绿素a和类胡萝卜素含量随着UV－B辐射的增强表现出逐渐降低的趋势，说明UV－B辐射增强对海洋微藻光合色素有严重的破坏作用。

| Abstract: | The effects of UV B radiation enhancement on photosynthetic pigments (chlorophyll a and carotenoid) are studied in Dicrateria inornata and Phaeodactylum tricornutum by means of batch culture method. Results show that lower dosage of UV B radiation has slight effects on the content of photosynthetic pigments; and higher dosage causes their decrease in Dicrateria inornata.The content of photosynthetic pigments in Phaeodactylum tricornutum decreases gradually with increasing dosage of UV B radiation. This indicated that UV B radiation enhancement could damage photosynthetic pigments of marine microalgae. |
