Effects of different salts and concentrations on germination and growth of Leymus chinensis

摘要：

Leymus chinensis is one of good‐quality and saline‐alkali tolerant grasses in the northern area of China with economic and ecological significance.The high concentration of salt ions is the main factor inhibiting L.chinensis seed germination in the sodic soil in Songnen plain, while the level of inhibition depends upon the concentrations and kinds of salt.This study is to investigate the effect of sodium salts ( NaCl,Na2 SO4,NaHCO3,Na2 CO3 ) and potassium salts ( KCl,K2 SO4, KHCO3,K2 CO3 ) on germination of L.chinensis.
