摘要:

通过实验生态学的方法,研究了赤潮异弯藻(Heterosigma akashiwo)、亚历山大藻(Alexandrium tamarense)和中肋骨条藻(Skeletonema costatum)的生长对UV-B辐射增强的响应。结果表明,UV-B辐射处理对赤潮异弯藻的生长始终表现出抑制效应,而低剂量的UV-B辐射处理对亚历山大藻和中肋骨条藻的生长有刺激作用,高剂量的UV-B辐射处理对亚历山大藻和中肋骨条藻的生长仍然显示出抑制作用。UV-B辐射对赤潮异弯藻、亚历山大

The sensitivity differences between three species of red tide microalgae to UV-B radiation treatment

Abstract:

The growth response of Heterosigma akashiwo, Alexandrium tamarense and Skeletonema costatum to UV-B radiation enhancement was studied in experiment by ecology methods. The results showed that the growth of Heterosigma akashiwo was inhibited by UV-B radiation, while lower dose of UV-B radiation stimulated the growth of Alexandrium tamarense and Skeletonema costatum. The 96h EC₅₀ values of UV-B radiation treatment to Heterosigma akashiwo, Alexandrium tamarense and Skeletonema costatum were 1.63 J/m², 2.34 J/m² and 2.58 J/m² respectively.

Key words: UV-B radiation sensitivity Heterosigma akashiwo Alexandrium tamarense Skeletonema costatum
