The comparison of photosynthetic physiological characteristics between Leymus chinensis and Leymus secalinus in the Songnen plains

摘要

L.chinensis and L.secalinus distributed widely in Songnen grassland,they could adapt to the habitats of different salinity and alkalinity gradient.The research of photosynthesis of L.chinensis or L.secalinus had great progress, but there no report about compare their photosynthetic characteristics.In this study, we tired to find some evidences for comparing and determining their photosynthetic physiological characteristics (Wang et al, 2001).
