| 摘 要： | 针对贵州省生产上大面积栽培的5个水稻品种进行稻纵卷叶螟抗(耐)性研究。结果表明:5个品种对稻纵卷叶螟的抗(耐)性存在显著差异,试验条件下T优618和黔优568的长势最好,卷叶率低,抗性级别表现为抗(R);B优811和奇优894表现为中抗(MR);金优431卷叶率最高,抗性级别为感虫(S)。对5个品种叶片和叶鞘等进行了物理性状的测定及对比,发现稻纵卷叶螟趋于危害植株低矮、主脉狭窄、叶片含水量高、硅化细胞含量低的品种。

| Abstract: | The results from studying leaf roller resistance of 5 main cultivation rice varieties showed that there was significant difference in rice leaf roller resistance between 5 tested varieties.Tyou618 and Qianyou568 with best growth vigor and lower leaf roll rate are of high resistance to rice leaf roller.B you811 and Qiyou 894 are of middle resistance to rice leaf roller and Jinyou431 with highest leaf roll rate is susceptible to rice leaf roller.The varieties with short plant height,narrow main vein,high wate... |
