研究了水稻品种内种子大小的变异程度及其对发芽和幼苗活力的影响。通过称量随机选择的一百个穗的单个谷粒来确定种子大小。将谷物分成四个大小类别：11-15、16-20、21-25和25-30 mg。最小和最大的种子之间的变异几乎是三倍，范围从11到30毫克。发芽率和幼苗活力指数值随着种子大小的增加而增加，这表明选择较大的种子建立良好的林分。
The extent of seed size variations within a rice variety and its effect on germination and seedling vigour were investigated. Seed size was determined by weighing individual grains of randomly selected one hundred panicles. Grains were sorted into four size classes : 11-15, 16-20, 21-25 and 25-30 mg. There was nearly a three-fold variation between the smallest and the largest seeds, which ranged from 11 to 30 mg. Germination rate and seedling vigour index values increased with the increase of seed size suggesting the selection of larger seeds for good stand establishment.
