Abstract
Double resistance soybean variety BX10 tolerance to aluminum toxicity with high-effect phosphorus and double-susceptible soybean variety BD2 were used as experimental materials,and the changes of water and osmotic regu-lating matters in soybean were studied under phosphorus deficiency and aluminum toxicity by hydroponic culture.The re-sults indicated that water potential in leaf of two soybean varieties was obviously decreased under phosphorus deficiency and aluminum toxicity,and the decreased level for BD2 and aluminum toxicity treatment was the highest.Moreover,the contents of soluble sugar and proline in root and leaf of two varieties were increased by two treatments,and the increased effects of BX10 and aluminum toxicity were obvious.Therefore,soluble sugar in leaf may be the main osmotic regulating matter at the early stage of stress,and proline maybe play a leading role at the later stage,they played a synergistic effect to improve the plant tolerance to stress.
