| 摘 要： | 通过3批播种试验,在自然条件下观察了始穗期降雨对不同水稻品种穗颈瘟发生的影响。结果表明:始穗期降雨对穗颈瘟发生的影响与品种的抗瘟性有关。根据始穗期与降雨相遇时各品种穗颈瘟的发病率,将供试的14个品种分为4个类群:第一类为中抗品种,第二类为中感品种,第三类为感病品种,第四类为高感品种。

| Abstract: | The field experiments with three batches of sowing were conducted to observe the influence of rainfall at the initial heading stage on the occurrence of neck blast of different rice cultivars in natural conditions.The results revealed that the effect of rainfall at the initial heading stage on the occurrence of neck blast was related to the blast resistance of rice cultivar.On the basis of neck blast morbidity of different cultivars under the condition of rainfall at the initial heading stage,the 14 tested ... |
