小麦产量及其构成因素的关系,不同栽培条件影响产量的变异主要是穗数的变异,每穗实粒数的变异次之,粒重的变异较小;穗数受栽培条件的影响最大,粒重受气候因素的影响较大。在小麦生产中,穗数的决定先于每穗实粒数的决定。穗数的多少势必会影响到每穗的粒数。
The relationship between the yield of wheat and its components is that the variation of yield under different cultivation conditions is mainly the variation of spike number. The variation of grain number per panicle is second to that of grain weight. Spike number is the most affected by the cultivation conditions Heavy subject to climate factors. In wheat production, the determination of the number of spikes precedes the determination of the number of spikes per panicle. The number of spikes is bound to affect the number of grains per spike.
