摘要 以5个水稻品种为试材,研究了不同品种的产量特性和灌浆特性。研究结果表明,参试的不同水稻稻品种的产量差异达到显著水平,其中辽粳294、辽优20、辽粳326和沈稻3号的产量较高,奥羽316的产量最低。沈稻3号、辽粳294和辽优20等3个品种的灌浆特性表现为明显的同步灌浆型,而奥羽316和辽粳326的灌浆特性表现为异步灌浆型。强、弱势粒间在起始灌浆势、最大灌浆速率和平均灌浆速度上都存在明显差异。水稻籽粒的灌浆速率和充实度在品种间以及同一品种的不同粒位间存在着较大的差异,即强、弱势粒同步灌浆型品种灌浆快、充实好,而强、弱势粒异步灌浆型品种则相反。 With five rice cultivars as entries, the yields, grain filling characters, and physiological characters during the period of grain filling were studied, and the relationships between different characters were analyzed. The results showed that the yield differences among rice cultivars reached significant level. The yields of Liaojing 294, Liaoyou 20, Liaojing 326 and Shendao 3 were higher than that of Oou 316, Shendao 3, Liaojing 294 and Liaoyou 20 filled synchronously in superior and inferior grains and Oou 316 and Liaojing 326 filled asynchronously. There were apparent differences between the superior and inferior grains in terms of initial filling power, maximum filling rate and mean filling rate. There also existed differences in the seeds' filling rate and grain plumpness between rice varieties or between different grain positions in the same cultivar. The cultivars with synchronous filling property filled rapidly and got plump grains, but the situations of cultivars with asynchronous filling property were the opposite.
