| 摘 要： | 在田间系统观察了土传小麦黄色花叶病对小麦植株影响的基础上,测定了不同病级单株产量损失,并提出了以株高、花叶程度及推迟生育期为主的病情分级标准。通过小区试验,导出了病情指数对产量的回归方程((?)(%)=99.458-0.836x)及相关系数(r=-0.997~(**))。

| Abstract: | Soil-borne wheat yellow mosaic disease is a virus disease of winter wheat in Ya'an District,Sichuan province,China.Effects of the virus on plants were systematically observed in the field.The yield losses for each level of the disease intensity were determined.The standard for the classification of diseased plants with reference to influences on plant height,mosaic and growth stages was put forward.The regression equation and correlation coefficient of the yield on disease intensity were calculated from the plot experiments. |
