摘要
分析了九江地区2001~2008年油菜产量性状与其生育期的平均气温、降雨量、日照3个气候因子的关系,结果表明：油菜荚果主要由第一分枝产生,与千粒重呈显著正相关;实际产量与单株荚果数呈极显著正相关,实际产量与苗期气温、营养生长气温、蕾薹期降雨量、蕾薹期日照、蕾薹期气温、开花期气温、开花期日照、灌浆期日照、灌浆期气温、灌浆期降雨量之间呈极显著相关。
The relationships between rape yield characters and some meteorological factors（average air temperature,rainfall and sunshine） in rape growth and developmental period from 2001 to 2008 in Jiujiang area were analyzed.The results indicated that the pod of rape was mainly produced from the first branch,and its number was significantly positively correlated with 1000-grain weight（P0.05）.The actual yield was significantly positively correlated with the number of pod per plant（P0.01）.There were significant correlations between the actual yield of rape and the air temperature at seedling,vegetative growth,bolting,flowering and milk stage,the rainfall at bolting and milk stage,and the sunshine at bolting,flowering and milk stage（P0.01）.
