摘 要: 研究结果表明,病情指数的倒数与培育年数的回归方程为:Y=0.01056+0.01601X。感病品种转变为抗病品种,过氧化物酶同功酶谱由多到少,过氧化物酶、多酚氧化酶活性由强至弱,抗坏血酸氧化酶活性由弱变强。 The authors give a regrssion equation between reciprocal of disease index and breedingvears number is Y =1/y=0.01056+0.1601x ,and we also found that peroxidase isoenzymezymogrames are decreased and the active peroxidase and polyphenol oxidase are weakened aswell as the active ascorbic acid oxidase is enhanced as converted the original susceptible vari-eties into high resistance ones.
