The disease severity of bacterial blight decreased after sprayed with nickel nitrate solution in rice seedilings. According to a plate test,nickel nitrate was slightly toxic to Xanthomonas oryzae pv.oryzae,so the decrease in disease index of bacterial blight was mainly due to induction resistance to X.oryzae pv.oryzae,by nickel nitrate in rice seedlings. The concentration of nickel nitrate ranging from 0.55 to 2.75 mmol/L was effective, of which,2.2 mmol/L had the optimum induction. Rice seedlings displayed...

The disease severity of bacterial blight decreased after sprayed with nickel nitrate solution in rice seedilings. According to a plate test,nickel nitrate was slightly toxic to Xanthomonas oryzae pv.oryzae,so the decrease in disease index of bacterial blight was mainly due to induction resistance to X.oryzae pv.oryzae,by nickel nitrate in rice seedlings. The concentration of nickel nitrate ranging from 0.55 to 2.75 mmol/L was effective, of which,2.2 mmol/L had the optimum induction. Rice seedlings displayed the strongest induction resistance to X.oryzae pv.oryzae when challenge inoculated with X.oryzae pv.oryzae 76 25 strain (high virulent) 3 days after the treatment of spraying the parts under the third leaf with 2.2 mmol/L nickel nitrate. The lesion length of pre treated rice leaves was 69.6% shorter than that of the control. On the 4th day after the treatment,the 3rd leaf of the crop was challege inoculated,from which the leaf acquired systemic resistance to bacterial blight.Its relative induction effect was 42.9%. The resistance effect induced by nickel nitrate lasted about 21 days.

Obviously effective systemic resistance was induced by nickel nitrate, PQ and p-AP. On the 4th day after tre atment, they displayed the most significant induction effect of resistance to XO O systemically. The severity of bacterial blight was reduced by 40.9%、35.5% and 27.6% respectively. Moreover, resistance induced by them was still relatively significant on the 8th day after treatment. Comparatively, nickel nitrate was th e best chemical inducer.
