摘　　要：通过水培试验,研究硫素营养对不同品种水稻叶片活性氧代谢的影响。结果表明,低硫或高硫胁迫下,水稻叶片膜脂过氧化产物丙二醛的含量有不同程度的提高,超氧化物歧化酶、过氧化物酶、过氧化氢酶和苯丙氨酸解氨酶等也有不同程度的改变,且其变化幅度因品种的差异而有所不同。说明不同品种水稻对硫素营养胁迫的抵御能力存在着基因型的差异。The membrane lipid peroxidation and various enzyme activities in leaves of different rice varieties were compared by using solution culture with different S concentration.It showed that S\|deficiency and S\|excessivity could increase the membrane lipid peroxidation,and the activities of enzymes, such as SOD, POD, CAT and PAL were also changed in different extent. The changes were somewhat different among the varieties tested, it may be connected with the genotype variance in the tolerance to sulphur nutrition stress. 
