玉米叶对我国几种典型赤潮藻生长的影响研究

研究了玉米叶对塔玛亚历山大藻(Alexandrium tamarense)、海洋卡盾藻(Chattonella marina)、赤潮异弯藻(Heterosigma akashiwo)、东海原甲藻(Prorocentrum donghaiense Lu)和球形棕囊藻(Phaeocystis globosa)生长的影响,以期为筛选新的、无污染的、廉价高效的除藻剂提供思路,为不同的有害赤潮的治理提供参考.结果表明,玉米叶对塔玛亚历山大藻、海洋卡盾藻、赤潮异弯藻、东海原甲藻和球形棕囊藻生长的影响明显不同.玉米叶可显著抑制塔玛亚历山大藻、海洋卡盾藻和赤潮异弯藻的生长,但对东海原甲藻生长的影响不大,对球形棕囊藻的生长则有显著的促进作用.这些结果表明,玉米叶对赤潮藻生长的抑制作用存在一定的选择性,这种选择性与藻的种属与细胞结构并无明显的相关性.

Study on effect of corn leave on growth of some HABs algae

The effects of the corn leaves on the growth of five HABs algae,Alexandrium tamarense,Chattonella marine,Heterosigma akashiwo,Prorocentrum donghaiense Lu,Phaeocystis globosa,were observed to provide more information on new algaecide with high efficiency,ecological security and selectivity.The corn leaves have the different influences on the growth of the five HABs algae.A.tamarense,C.marine and H.akashiwo distinctly inhibited,in contrast,P.globosa was accelerated.However,P.donghaiense treated with the corn ...
