Abstract
Two rice cultivars, Yushuinu (resistant) and Zhefu 802 (susceptible), were used in this study. At 2\|leaf stage, their second leaves were re\|treated with PQ and Tiron. Activities of CAT and POD, relative contents of fatty acid in membrane and MDA contents were determined after 3, 24, 48 and 72 hours respectively. At 3\|leaf stage, the third leaves were challenged with. Xanthomonas oryzae pv. oryzae 76 25 (virulent), and disease development status was examined 15 days latter. The relation between disease resistance to XOO and peroxidation on membrane lipid induced by paraquat and Tiron was studied. The results show that pre\|treatment with PQ induces systematic resistance to strain 76\|25, and increases the activities of both CAT and POD, and MDA contents in the treated leaves. The changes begin from 24 hours on and keep at a higher level from 48 to 72 hours after the treatment. On the average, CAT activities increase by 16 5 and 11 3 percent, POD activities by 37 2 and 25 3 percent, MDA contents by 38 5 and 32 2 percent in treated leaves of Yushuinu and Zhefu 802 respectively. The saturate fatty acid increase by 11 8 percent and IUFA decreases by 7 5 percent, in the leaves in Zhefu 802 treated with PQ. The decrease of IUFA is due to the decrease of linolenic acid contents. Tiron shows a negative effect on the induced resistance to XOO 76\|25 and on the changes of above tested items caused by PQ.
