| 摘 要： | 应用75个水稻品种(系),研究了生育期冷水灌溉对寒地水稻主要农艺性状的影响.结果表明,在主要农艺性状中,结实率的冷水反应指数(CRI)值相对较小,受低温冷害程度较大,穗粒数和秆长的CRI值相对较大,低温冷害对其影响较小;相关分析表明:穗颈长和结实率的CRI值与秆长的CRI值均呈极显著正相关,穗长的CRI值与秆长的CRI值呈显著正相关;穗颈长的CRI值与结实率的CRI值呈极显著正相关;穗粒数的CRI值与穗长的CRI值呈显著正相关. |

| Abstract: | 75 varieties or lines were studied on effect of irrigation in growth duration on some agronomic traits of rice in cold region.The results showed that value of cold water response index(CRI) of seed setting rate was low,but CRI of seed spike lets per panicle and CRI of culm length were high.Correlating analysis indicated that CRI value of culm length was very significant positively correlated to that of panicle neck length and seed setting rate,and was significant positively correlated to that of panicle length;CRI value of panicle neck length was very significant positively correlated to that of seed setting rate;CRI value of grains per panicle was significant positively correlated to that of panicle length. |
| Keywords: | rice cold tolerance agronomic traits |
