摘　　要：系统评估了云南省内广泛栽培的16个草莓品种对拟盘根腐病的抗性表现,并运用分光光度法测定了不同品种草莓叶片的生理生化指标,旨在探究这些指标与其对拟盘根腐病抗性的潜在关联.试验结果显示,不同草莓品种在抗性上展现出显著的差异,具体表现为:有3个品种(占18.75%)展现出高度抗性,以建德红为代表;5个品种(占31.25%)表现为中等抗性,以天仙醉为代表;有4个品种(占25%)为中感品种,以红颜为代表;有4个品种(占25%)为高感品种,以甜查理为代表.高抗品种建德红、越秀、蒙特瑞的拟盘根腐病病情指数分别仅为4.55、6.37和9.09;高感品种甜查理、宁玉的病情指数高达50.30和55.76.接种棒状拟盘多毛孢后,抗性品种叶片可溶性蛋白和脯氨酸含量均显著高于感病品种,丙二醛含量显著低于感病品种,而叶绿素含量与抗病性无显著相关性.高抗品种建德红、越秀、蒙特瑞可在云南进一步推广种植.The resistance performance of 16 strawberry varieties widely cultivated in Yunnan Province were evaluated systematically to the root rot of N.clavispora.The differentiated strawberry variety leaves were determined by the spathered optical method for the physiological and biochemical indicators,which intended to explore the potential correlation between these indicators and their resistance performance to the root rot of N.clavispora.The experimental results showed significant differences in resistance performance among different strawberry varieties,and the specific manifestations are 3 varieties accounting for 18.75%,showing high resistance performance with the representative of Jiandehong,5 varieties accounting for 31.25%,showing middle resistance performance with the representative of Tianxianzui,4 varieties accounting for 25%,showing middle sense with the representative of Hongyan and 4 varieties accounting for 25%,showing high sense with the representative of Tianchali.The root rot of N.clavispora disease indicators of high resistance varieties,including Jiandehong,Yuexiu and Monterey were only 4.55,6.37 and 9.09,respectively,but the disease indicators of the high sense varieties were as high as 50.30 and 55.76.After inoculation with spore of N.clavispora,the soluble protein and proline concentrations in the leaves of resistant varieties were significantly higher than those of susceptible varieties,while the malondialdehyde concentration was significantly lower than that of susceptible varieties.However,there was no significant correlation between chlorophyll concentration and disease resistance.High-resistant varieties Jiandehong,Yuexiu and Monterey can further widely planted in Yunnan.
