水稻饱满粒率是平均每穗可成为糙米的饱满粒数占平均每穗总粒数的百分数。它是衡量水稻源库流是否协调的重要指标,与产量的高低有密切关系,近年来,辽宁省推广的水稻品种单位面积穗数或粒数均有所提高,而饱满粒率则似有下降的趋势。本文从品种的穗形及源库关系入手,对品种间和品种内饱满粒率的差异及其形成原因进行了初步研究,以为水稻高产育种和高产栽培提供参考。一、材料与方法试验于1983～1985年在沈阳农业大学稻作研究室试验田进行。供试材料为穗型不同的粳
The full grain rate of rice is the percentage of full grains per panicle that can be brown rice on average. It is a measure of rice source and sink flow is an important indicator of coordination, and the level of production is closely related to Liaoning Province in recent years, rice varieties popularized per panicle area or grain number has increased, while the full grain rate seems to decline the trend of. This article starts with the relationship between the spike shape and the source and sink of the cultivars, and makes a preliminary study on the difference of the full grain rate among cultivars and cultivars and the reasons for their formation, in order to provide reference for the high-yield breeding and high-yielding cultivation of rice. First, the material and method test in 1983 to 1985 in Shenyang Agricultural University, Rice Research Laboratory experimental field. The tested materials were different japonica type
