Progress in drought resistance and cold tolerance of artificial pastures in northern arid areas
Drought and low temperature are important factors that limit the growth and survival of artificial pastures in northern arid areas in China.This paper described cold and drought resistances of six pastures including Medicago sativa,Leymus chinensis,Elymus sibiricus,Elymus nutans,Bromus inermis and Agropyron cristatum and summarized their adaptive mechanisms to drought and low temperature stresses from the perspectives of morphological structure,production,physiological and biochemical characteristics,antioxidase system,and osmoregulation substrate.At last,the future research directions were prospected.
