摘要
采用BG11培养基,设置日光、500、1 000、2 000、2 500、3 000、4 000 lx的光照强度梯度,用分光光度法测定各组培养液叶绿素a的含量,研究光照强度对雨生红球藻生长速率的影响.结果表明,2 500 lx为雨生红球藻株的最适光照强度,其叶绿素含量随培养时间延长而增长,第8 d其叶绿素a含量达到最大值,之后呈现下降趋势.
The growth of Haematococcus pluvialis is very different under various light intensities. Haematococcus pluvialis is used as experimental material,and is cultivated in the BG11 culture medium. The experiment are carried out separately as the single factor test when seven illuminations（500,1 000,2 000,2 500,3 000,4 000 lx and sun light）. The chlorophyll a content of the green vegetative cell has been tested. The results show that the appropriate light intensity of the green algae is in 2 500 lx. The content of chlorophyll arrives at most value after 8 days in culture.
