| 摘 要： | 以江苏地区生产上常用的水稻品种武粳15、武运粳7号、扬辐粳7号和扬粳9538为材料,探讨了水稻品种对灰飞虱若虫发育进程的影响。研究表明,灰飞虱若虫取食武粳15、武运粳7号、扬辐粳7号和扬粳9538后的发育历期分别为17.30d、15.69d、21.14d和20.87d。经方差分析与多重比较,灰飞虱若虫总历期在扬辐粳7号与扬粳9538之间不存在显著差异,这两个品种上若虫的发育历期与武粳15和武运粳7号之间均存在显著差异,同时,武粳15与武运粳7号之间灰飞虱的若虫历期也存在明显差异。这表明水稻品种不同,灰飞虱若虫的发育进度不同。

| Abstract: | Four rice varieties,wujing 15,wuyunjing 7,yangfujing 7 and yangjing 9538,popularly used in Jiangsu Province,were conducted to evaluate their effects on the nymph development.The results showed that the nymph development durations on wujing 15,wuyunjing 7,yangfujing 7 and yangjing 9538 were 17.30d,15.69d,21.14d and 20.87d,respectively,and that of yangfujing 7 and yangjing 9538 were significantly later than that of wujing 15 and wuyunjing 7.It is indicated that wujing 15 and wuyunjing 7 are more susceptible to the nymph than yangfujing 7and yangjing 9538. |
