选择具有不同抗病性水稻品种 -稻瘟菌小种组合 ,在室内、田间分别设 7个、3个不同氮肥水平 ,测定不同组合不同氮肥水平下品种 -小种相对寄生适合度 ,方差分析结果表明 ,施氮量对品种小种相对寄生适合度的影响较小。相对寄生适合度可以作为一项较为稳定的参量用于水稻品种与稻瘟病小种互作研究。
In order to determine the relative parasitic fitness and relative parasitism of different races with different nitrogen levels, the results of analysis of variance (ANOVA) The results showed that the effect of nitrogen application on the relative parasitism fitness of races was small. Relative parasitic fitness can be used as a more stable parameter for the interaction of rice varieties and rice blast interplants.
