摘要:
在UV-B辐射的作用下,采用共培养的方法,通过测定藻细胞数量,研究UV-B辐射对不同起始浓度的米氏凯伦藻(Karenia mikimotoi Hansen)和赤潮异弯藻(Heterosigma akashiwo Hada)两种赤潮藻之间的种间竞争关系的影响。结果表明:1) 不同起始浓度对米氏凯伦藻和赤潮异弯藻种群竞争关系有明显的影响。当米氏凯伦藻(K)和赤潮异弯藻(H)的接种比例为4:1和1:1时,米氏凯伦藻在竞争中占优势;当K:H为1:4时,赤潮异弯藻在竞争中占绝对优势。2) UV-B辐射可改变米氏凯伦藻和赤潮异弯藻之间的种群竞争关系。当有UV-B辐射作用时,两者的种群密度都减小,且当K:H = 1:1时,赤潮异弯藻占优势,其余两组的竞争优势保持不变。综上所述,UV-B辐射对赤潮微藻之间的种群竞争有明显的影响作用,为研究UV-B辐射对赤潮的影响提供有力的依据。

Abstract: In the role of UV-B radiation, using the method of co-culture, by measuring the number of algal cells to study UV-B radiation on different initial concentrations of Karenia mikimotoi Hansen and Heterosigma akashiwo Hada affect interspecific competition between the two red tide algae. The results demonstrated the different inoculative proportions of K. mikimotoi and H. akashiwo ap-parent effects on interspecific competition between them. When the inoculative proportion of K. mikimotoi and H. akashiwo was 4:1 and 1:1, K. mikimotoi would be in predominance in the compe-tition. However, H. akashiwo would be absolute advantage in the competition when K:H was 1:4. The UV-B radiation could change the competition relationship between K. mikimotoi and H. akashiwo. But both of the population densities were decreased. When K:H was 1:1, H. akashiwo was in predominance and the competition of the other two groups was unchanged. In conclusion, UV-B radiation plays an important effect on the competition between both of the microalgae, it could offer powerful basis for researching how UV-B radiation to effect red tide.
