In order to determine the role of microwave pretreatment seed of Isatis indigotica on photosynthesis, growth and development, the content of photoproducts and chlorophyll, net photosynthetic rate, stomatal conductance and water use efficiency and development of the seedlings have been studied. 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, 8s pretreatment is the best among four treatments. Moreover, the influence mechanism of laser irradiation on seeding photosynthesis has been discussed on the basis of above results.
