摘要
分析不同绿豆品系的产量和光、温反应,确定不同绿豆品系对光、温反应的敏感性。以2012—2014年国家绿豆区域试验14个参试品系为试验材料,于全生育期记录各品系平均温度、平均降水和光照时间,并干成熟期分期采摘,全区计产,分析不同绿豆品系对产量和气象因子的敏感性。试验结果表明,不同品系的产量高稳系数存在差异,品系10(维绿8号)高稳系数最高,较对照品系增加54.3%;不同绿豆品系的光、温、水反应特性差异显著,其中有9个品系(品系1,2,3,6,7,8,10,11,12)的光稳系数高于对照(P<0.05),7个品系(品系1,2,3,6,7,8,11)的温稳系数高于对照(P<0.05),8个品系(品系1,2,3,6,7,8,10,11)的水稳系数高于对照(P<0.05);以光稳系数、温稳系数和水稳系数为基础对14个绿豆品系进行划分,其中对环境反应稳定的品系4个、敏感的品系有4个和中间类型的有6个。夏播绿豆不同品系对环境反应的敏感程度分为稳定型、中间类型、敏感型,其中属于中间类型的绿豆品系10能够获得更高更稳定的产量。
In order to obtain the responses of different mungbean varieties to climate factors,we analyzed the relationship between the factors,including light,temperature,rainfall,and yields of different mungbean varieties.Mungbean varieties from region test in 2012—2014 were used as test materials in the present study.We recorded average temperature,average rainfall,and light time every day during the entire growing season,harvested and analyzed their yields at different stages during the maturation period in all plots.The results indicated that YHSCs of different varieties were different;YHSC of the variety 10 was the highest with the increase by 54.3% compared to the CK.The responses of different mungbean varieties to climatic factor were different;Light stalilization coefficient（LSC,） of 9 varieties（1,2,3,6,7,8,10,11,12） were much higher than that of CK（P 〈0.05）;Temperature stabilization coefficient（TSC_i） of 7 vari-eties（1,2,3,6,7,8,11） were much higher than that of the CK（P 〈0.05）;Rainfall stabilization coefficient（RSC_i） of 8 varieties（1,2,3,6,7,8,10,11） were also much higher than that of CK（P 〈0.05）.According to the factors inclusive of LSC,TSC and RSC,different mungbean varieties responding to environment change can be divided into 3 categories,such as stability response,intermediate response,and sensitivity response.To the tested varieties,4,6,and 4 varieties belong to stable response,intermediate response,and sensitive response,respectively.In addition,the variety 10,as an intermediate response,had high and stable yield.
