STUDIES ON THE ADAPTAEITY AND TO LERANCE OF LEYMUS CHINENSIS TO SALINITY IN SALINIZED GRASSLAND IN THE SONGNEN PLAIN
松嫩平原盐碱化草地羊草的生长适应性及耐盐生理特性的研究

he biomass and physiological index of Leymus chinensis in different salty habitats areanalysized.The results show that L. chinensis distributes in a wide ecological variability,be-cause it can adapt to the habitats of different salinization gradients.It can grow well if soilhas a conductivity is reflected in uptaking inorganic ions and accumulating proline in a largemount to improve regulation of osmosis. When the conductivity is lower than 0. 7mS/cm,itmainly relies on uptaking inorganic ions to have such a...
