| 摘 要： | 采用波长650nm，功率40mW，功率密度13W／cm^2的半导体激光，对紫球藻（Porphyridium cruentum)进行诱变，辐照时间分别为5min、10min、20min。通过对紫球藻每天细胞数、叶绿素a、第7d细胞干重和胞外多糖产量的测定可知：与对照组比较，3个处理对紫球藻生长及胞外多糖产生影响，5min、10min均有不同程度的促进作用，其中5min作用最明显，而20min则有抑制作用。

| Abstract: | It was irradiated by LD laser(wave length 650nm,power 40mW,power density 13mW/cm 2),with does of 5min,10min and 20min The results showed the different does of LD laser affected the dry weight,the growth,the polysaccharide and chlorophyll a of Porphyridium cruentum The does of 20min restricted producing chlorophyll a and the polysaccharide,5min and 10stimulated producing diorophyll a and the plysaccharide,the 5min does was in best |
