摘要: 利用多因子实验设计,研究了主要环境因子温度、盐度和光照强度对麻痹性贝毒产毒藻——塔玛亚历山大藻(Alexandrium tamarense)生长的影响.经三维ANOVA统计分析(Tukey test)结果表明,在实验条件范围内(温度12,19,25,32℃;盐度10,18,25,30,35和光照强度0.02×1016,0.08×1016,0.3×1016,1.6×1016s-1/cm2),温度、光照强度和盐度对藻生长率有显著的影响(P<0.001).光照强度和温度、盐度和温度、光照强度和盐度以及这3个因子之间存在显著的相互作用(P<0.001),在本实验中该藻生长的最适条件是19℃,1.6×1016s-1/cm2,盐度30.根据塔玛亚历山大藻的生长特性,我们探讨了这些环境因子在塔玛亚历山大藻赤潮形成机制中的作用.Abstract: Three-factors experiment design is used to study the combined effects of temperature,salinity and irradiance on the growth of an important PSP(paralytic shellfish poisoning) producing species A.tamarense(a strain isolated from the Daya Bay,Uuangdong,China).The results show that growth of A.tamarense is significantly different among temperatures(12,19,25,32℃),irradiance(0.02×1016,0.08×1016,0.3×1016,1.6×1016 s-1/cm2) and salinity(10,18,25,30,35).There are interactive effects between any two of and among all three physical factors on the growth of A.tamarense.The optimal growth condition of A.tamarense is 19℃,30 and 1.6×1016s-1/cm2 with growth rate of 0.25d during exponential growth phase.Therefore,A.tamarense is more likely to bloom under relatively high temperature and high illumination in spring and autumn,and this species is able to grow in ocean area of relatively high salinity.Red tide formation mechanism and possible distribution of this species in China are also discussed.To protect mariculture industry and human health,more attention should be paid to this toxic species.
