Abstract
With sandy culture, effects of low phosphorus stress on membrane lipid peroxidation and protective enzyme activities in rice seedlings of low phosphorus tolerant cultivars(Dalidao, Liantangzao 3) and low phosphorus sensitive cultivars(Huzhanqi, Xinsanbaili) were studied. Results indicated that low phosphorus stress aggravated the membrane lipid peroxidation in rice leaves, which was more severe in low phosphorus sensitive cultivars than that in low phosphorus tolerant cultivars. During the stress period, SOD, CAT, POD activity in low phosphorus tolerant cultivars maintained relatively stable, whereas those in low phosphorus sensitive cultivars increased obviously at early stage, then decreased rapidly, which might suggest that the activities of protective enzyme system had no significant relation with low phosphorus stress, but its trend did so.
