摘要
以 3种单细胞海洋藻类 :新月菱形藻、亚心形扁藻、湛江叉鞭金藻为实验材料 ,研究了几种外界因子 6 -苄氨基腺嘌呤 (6 -BA)和二脘基氨基乙醇羧酸酯 (DA - 6 )、盐度、铬等对其生长、光合作用、呼吸作用、叶绿素合成及SOD酶谱的影响 .结果表明 ,在一定的浓度范围内DA - 6和 6 -BA对藻类的生长有促进作用 ,超过一定浓度 ,则有抑制作用 .在一定的盐度范围内 ,藻类的增长随着盐度的加大而加快 ,而超过一定范围 ,则盐度越大 ,生长越慢 ,盐度对藻类光合作用、呼吸作用及叶绿素合成的影响也大致如此 .而铬则明显地抑制藻类叶绿素的合成 ,降低酶活 ,对藻类有很大的毒害作用 .
Three singal-cell alage were used to study some outer factor effect (6-BA and DA-6,salt,Cr 3+ ),such as growth,photosynthesis,respiration,chlorophyll synthesis and SOD enzyme.It shows that to a certain extent of concertration,DA-6 and 6-BA can accelerate the growth of algae,but beyond the concentration range,it restrain the growth;to a certain extent of salt,algae growth became faster along with the salt concentration increasing,beyond the range,algae grow slower with the concentration increasing.And salt effect on algae were just much the same.Cr 3+ can restrain chlorophyll synthesis,reduce enzyme activity obviously,and has a great poison to them.
