【摘要】 采用喷雾接种法对梨4个种28个品种的果实进行了轮纹病抗性鉴定，结果表明：不同品种果实抗性不同，水红宵、金梨、八月酥、栖霞小香水、居里、黄县长把、秋子表现抗果实轮纹病；不同品种群间抗性差异显著，白梨系统中存在着丰富的抗性资源；不同品种感病程度不同，西洋梨品种三季单果侵染点数最多，感病最重；不同品种贮藏期发病速度不同；套袋对控制果实轮纹病的发生起显著作用。更多还原

【Abstract】 The fruit resistance to ring-rot disease(Physalospara piricola Nose) of 28 pear varieties were studied by spray-inoculation. Results showed: Shuihongxiao,Jinli,Bayuesu,Qi xia Xiaoxiangshui,Cure,Huangxian Changba and Qiuzi were resistant. The resistant ability of the varieties of 4 species was distinctly different, the more resistant resources of P. bretschneiderderi Rehd. were likely to be found. The infection level among varieties was different, P. communis L. Cultivar,Dr Julio Guyo was seriously infected. Fruit-bagging could obviously reduce the occurrence of ring-rot.更多还原
