| 摘 要： | 采用经臭氧处理的海水培养小球藻，分析了小球藻的相对增长速率、叶绿素-a含量，DNA和RNA含量及海水中三氮含量的变化，结果表明：1、一定剂量的臭氧处理可提高小球藻的生长速度和叶绿素的含量，高剂量的处理会抑制小球藻的生长。2、藻细胞中DNA含量对臭氧处理表现的相对稳定，而RNA含量比较敏感，一定剂量的臭氧处理可引起RNA含量增加。3、经臭氧处理的海水，硝态氮（NO3^--N)的含量有所提高，而铵态氮（NH4^ -N)和亚硝态氮（NO2^--N)的含量降低。

| Abstract: | Effects of seawater treated by ozone on reproduction, chlorophyll a content, DNA and RNA content in Chlorella sp.were studied. Meanwhile, NH 4 N, NO - 2 N and NO - 3 N content in the seawater were analyzed. The results showed as follows: 1. A certain concentration of ozone treatment could increase reproduction and chlorophyll a content, but higher concentration of ozone treatment could inhibit repraduction of Chlorella sp.. 2. DNA content showed relative stability, RNA content was more sensitive to ozone treatment than DNA content, and ozone treatment could increase RNA content. 3. NH 4 N and NO - 2 N content in seawater by ozone treated decreased, while NO - 3 N content increased compared with that in control seawater. |
