摘　　要：以菘蓝 (isatisindigotica)为实验材料 ,研究了He Ne激光辐照中药菘蓝种子对幼苗光合色素含量、净光合速率、气孔导度与蒸腾速率、可溶性糖含量及总生物量的影响。研究结果表明 ,4种处理均能不同程度提高菘蓝幼苗光合色素含量、净光合速率水平、气孔导度与蒸腾速率 ,可溶性糖含量及总生物量 ,比较而言 ,5min的He Ne激光处理效果最好。The effects of He Ne laser pretreatment on the seed of isatis indigotica have been studied in the following aspects,such as content of photoproducts and chlorophyll,biomass,net photosynthetic rate,stomatal conductance and water use efficiency.The results indicated four treatments have improved apparently the content of photoproducts and chlorophyll,stomatal conductance,water use efficiency,level of net photosynthetic rate and so on.Compared with the control,5min treatment is the best among four treatments.Moreover,the influence mechanism of laser irradiation on seedling photosynthesis has been discussed on the basis of the above results.
