摘　　要：为了明确大麦籽粒灌浆期β-淀粉酶动态与气象因子的内在联系,对两年间5个大麦品种籽粒灌浆期β-淀粉酶动态与气象因子进行了相关分析。结果表明,大麦籽粒灌浆期的β-淀粉酶活性呈升-降-升的动态过程,在成熟期达到最大值。偏相关分析和多元回归分析表明,大麦籽粒灌浆期β-淀粉酶活性与总积温呈极显著正相关,与总日照时数和日均日照时数的互作呈显著相关,与日均温、日均日照时数呈显著负相关,与总积温和日均温的互作、总雨量和日均日照时数互作呈极显著负相关,偏相关系数从大到小依次为总积温、总雨量和日均日照时数交互作用、总积温和日均温交互作用、总日照时数和日均日照时数交互作用、日均日照时数、日均温。In order to determine the relationship between the accumulation dynamic of β-amylase in barley grain during filling stage and the meteorological factors, the correlation analysis was carried out using five barley varieties in two years. The results showed that the activity of β-amylase in barley grain showed the change of increasing, decreasing and increasing during filling stage, and the maximum value occurred at maturity stage. Partial correlation analysis and multiple regression analysis showed β-amylase activity in barley grain was significantly positively correlated with total accumulated temperature, significantly correlated with interaction of total sunshine and average daily sunshine, significantly negatively correlated with the daily average temperature and average daily sunshine, extremely significantly negatively correlated with the interaction of total accumulated temperature and daily average temperature and the interaction of total rainfall and daily average sunshine. The partial correlation coefficients from big to small in order is total accumulated temperature, interaction between total precipitation and daily average sunshine, interaction between total accumulated temperature and daily average temperature, interaction between total sunshine and daily average sunshine interactions, daily average sunshine, and daily average temperature.
