Abstract
Rice seedlings were inoculated to the third leaf with Xanthomonas oryzae pv. oryzae two days after treating with 1.0 and 2.0 mmol/L nickel nitrate solution. The lesion length of the leaf in the two treatments was shorter by 42.1% and 48.0%, respectively, than that in the CK after 2 weeks, which indicated that nickel nitrate had induced resistance to bacterial leaf blight in rice seedlings. Determination of some physiological indices showed that the activity of peroxidase (POD), polyphenol oxidase(PPO) and phenylalanine amminia-lyase (PAL) and the content of lignin were all promoted or increased significantly in the leaves of rice seedlings after the treatment of nickel nitrate. Meanwhile, most of isozyme bands of POD and 4 isozyme bands of PPO were strengthened compared with those of the CK. Therefore, it is suggested that increase in the activity of POD, PPO and PAL and the content of lignin in leaves after treatment may involve in the resistance to bacterial leaf blight induced by nickel nitrate in rice seedlings.
