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。
