利用水培试验研究了不同基因型甘蔗在缺磷条件下的叶片膜脂过氧化和保护酶系统的变化．结果显示缺磷能引起甘蔗叶片膜脂过氧化程度的提高及保护酶系统活性的改变，不同基因型的变化方式和幅度不同，与其耐低磷特性之间有一定的相关性．
Hydroponic experiments were conducted to study the changes of membrane lipid peroxidation and the protective enzyme system in different genotypes of sugarcane under phosphorus deficiency conditions. The results showed that phosphorus deficiency could induce the increase of membrane lipid peroxidation and the activity of protective enzyme system in sugarcane leaves. The variation patterns and amplitudes of different genotypes were different, which had some correlation with their tolerance to low phosphorus.
