| 中文摘要: |
| 鉴于国内至今尚无水稻条纹叶枯病品种抗性鉴定标准的现状，本文分别研究了接种时间、接种强度与水稻接种苗龄3因素对抗性鉴定的影响。结果表明水稻条纹叶枯病的适合抗性鉴定方法应为：接种时间48～72 h, 接种强度2～6头/株和水稻接种龄期0.5～1.5叶龄。以本研究结果为基础制定了水稻条纹叶枯病品种抗性鉴定的江苏省地方标准。 |
| 英文摘要: |
| The influences of inoculation time, inoculation intensity and inoculation stage of the seedlings on the resistance identification of rice cultivars to rice stripe disease were investigated, since there have been no standard methods in China so far.The results revealed that 48-72 hours after inoculation, 2-6 insects/seedling and 0.5-1.5 leaf age were the optimal conditions for resistance identification.Based on the results of the studies, the local standards were formulated in support of quality and technical supervision for Jiangsu Provincial Bureau. |
