摘要
对来自不同地区的多个水稻品种进行芽期耐冷性试验,结果表明:15份优质水稻品种发芽期14℃、7 d处理,耐冷性均表现为极弱;14℃、14 d处理,龙稻18、通禾66耐冷性表现为极强,九稻68、吉粳511耐冷性表现为强。在芽期试验中,所有品种芽期耐冷性为强。
The cold tolerance of rice is an important index to resist low temperature injury.Among them,cold tolerance in bud stage is an important period of cold tolerance in rice.In this study,a number of rice varieties from different regions were tested for cold tolerance at budding stage.The results showed that 15 high-quality rice varieties showed extremely weak cold tolerance at 14℃for 7 days."Longdao 18"and"Tonghe 66"showed extremely strong cold tolerance,while"Jiudao 68"and"Jigeng 511"showed strong cold tolerance.In the bud stage test,all varieties had strong cold tolerance at bud stage.
