摘    要:以目前河南省生产上大面积推广的高肥小麦品种和洛阳市农科院新培育的小麦品种为材料,用Logisitic方程对不同习性小麦品种的籽粒灌浆过程进行了拟合,用相关分析研究了灌浆参数与粒重的关系。结果表明:对所有参试品种来说最大灌浆达到时间Tmax、最大灌浆速率Rmax、平均灌浆速率R和各阶段灌浆速率是影响粒重的主要因素,而且R对粒重的影响达极显著水平;而对春性品种,与粒重显著相关的灌浆参数为Rmax、R、R2;半冬性品种,平均灌浆速率R、R1和T2与粒重显著相关。

关 键 词:小麦  灌浆参数  灌浆速率  粒重  相关分析

Abstract:The popular wheat varieties in Henan and the cultivars bred by Luoyang Academy of Agricultural Sciences were used to study the relationship between the filling parameter and grain weight.The Logisitic equation was used to simulate the filling course in different wheat varieties.The result showed that the maximum filling time Tmax,maximum filling rate Rmax,average filling rate R and the filling rate at each stage were the main factors which affected the gain weight,and R mostly affected the grain weight.For spring characteristic wheat,the grain filling parameters had extreme correlation with Rmax,R and R2;For semi-winterness wheat variety,R,R1 and T2 were extremely related to grain weight.
Keywords:Wheat  Filling parameter  Filling rate  Grain weight  Correlation analysis
