Abstract:
Taking Selaginella tamariscina and Selaginella sanguinolenta as experimental materials，the photosynthetic characteristics of the leaves under different light intensity(no shading(control CK：light transmittance 100%),single shading(light transmittance 70%)，double shading(light transmittance 50%)，three layer of shading(light transmittance 20%)) were studied.The results showed that the 2 species of Selaginella in no shading and single shading conditions，net photosynthetic rate was higher than the other two treatment of Selaginella;Selaginella tamariscina diurnal variation of net photosynthetic rate curve for Shuangfeng，had obvious midday depression，but Selaginella sanguinolenta midday depression was not obvious.The degree of recovery from midday depression，Selaginella tamariscina illumination adaptability was wider than Selaginella sanguinolenta Chlorophyll content and specific leaf weight changed further proved the point.
