摘要
为了探究气象因子对油菜籽含油量的影响,试验将连续5 a的气象因子与6个油菜品系含油量进行相关分析和逐步回归分析。结果表明,花期至成熟期日平均气温(D1)对品系NH610含油量有显著负向影响;花期至成熟期日相对湿度(D4)对品系NH273、NH160含油量有显著负向影响;花期日相对湿度(H4)对品系NH931含油量有显著负向影响;角果期日相对湿度(P4)对品系NH330含油量有显著负向影响;角果期日平均气温(P1)对品系NH605含油量有显著负向影响。
To explore the influence of climate factors on the oil content of rapeseed,the correlation analysis and stepwise regression analysis were carried out between several meteorological factors and oil content of six rapeseed varieties in Yuncheng from 2015 to 2019.The results showed that the daily average temperature at blooming to maturity period(D1)had a significant negative effect on the oil content of NH610 variety.The daily relative humidity at blooming to maturity period(D4)had a significant negative effect on the oil content of NH273 and NH160 variety.The daily relative humidity at blooming period(H4)had a significant negative effect on the oil content of NH931 variety.The daily relative humidity at pod period(P4)had a significant negative effect on the oil content of NH330 variety.The daily average temperature at pod period(P1)has a significant negative effect on the oil content of NH605 variety.
