摘要
以１６个农艺性状不同的小麦品种为材料，研究了不同类型小麦品种的灌浆特性。结果表明：籽粒增重表现慢－－快－－慢３个时期，其变化规律可由三次多项式进行拟合；不同品种的灌浆速率和最大灌浆速率差别较大，而灌浆持续期无明显不同；品种成熟期与籽粒灌浆持续期无相关性。
With 16 winter wheat cultivars which had different kinds of agronomy characteristics, the characters of grain filling were studed. The main results showed that the grain development could be divided into 3 periods in which the dry matter showed slow-fast-slow accumulation, and this dynamic patterns could be simulated by acubic polynomial regression equation Y=a+bx+cx 2 +dx 3 . The significant varietal differences were observed in filling rate and maximum filling rate in different cultivars,but not in filling period. There were no correlation between grain filling period and ripening time of plant.
