In the aspect of grass cold tolerance, these ten grasses were classified into three types by the cluster analysis, based on winter survival adaptability and LT50 measured under low temperature treatment. High cold tolerance: Bromus biebersteinii,Bromus inermis,Festuca arundinacea, Agropyron desertorum,Elytrigia elongate, Phleum pretense; medium cold tolerance: Festuca rubra, Agropyron smithii,Dactylis glomerata; low cold tolerance: Phalaris arundinacea.

Under P-deficiency stress, IAA concentration in asparagus bean plant increased, and IAA translocated from shoot to root, then IAA concentration in root increased, and the ratio of IAA concentration in root/that in young stem and leaf increased, then the ratio of root/shoot increased, due to more carbohydrate translocated to root.

缺磷胁迫下长豇豆幼苗IAA浓度升高，并从地上部向根系运转，使根系IAA浓度和根系IAA含量/嫩茎叶IAA含量的比值升高，增强了碳水化合物向根分配的力度，促进了根冠比的提高，对缺磷敏感的二芦白升高最大，因而根冠比也升高最大。
