The comparison studies of ecological and water regulation characteristics of Caragana microphylla and Caragana stenophylla
小叶锦鸡儿和狭叶锦鸡儿的生态和水分调节特性比较研究

The studies of specific evolution of genus Caragana demonstrate that pinnately compound leaf group is preliminary, and pseudo-palmately compound leaf group belongs to the relative evolved. Pinnately compound leaf group gradually evolved into pseudo-palmately compound leaf group with the increase in the degree of drought. This point of view is based on studies of the geographical distribution and the morphological characteristics of plants, but lacks physiological and biochemical proof. The characteristics o...
