Abstract
Leymus chinensis and Leymus secalinus are perennial rhizome grasses; photosynthetic physiological characteristics were compared between them in Sandy and Saline-Alkaline Soils on the Songnen Plains of China. The contents of chlorophyll and soluble saccharides were positively correlated with photosynthetic characteristics. The photosynthetic capacity of L. chinensis was significantly greater than L. secalinus, with great economical and ecological potentials. L. chinensis has better adaptaion to the saline-alkali condition than L. secalinus.
Key words: Leymus chinensis, Leymus secalinus, photosynthesis, water soluble carbohydrate, growth.
