分蘖期是大麦最重要的发育阶段之一,对于产量有决定性的影响(Kirby等,1972).分蘖数和分蘖成穗数取决于分蘖期的环境条件.单株分蘖数有时在幼苗定株之后才能达最高值,它们在抽穗之前开始迅速减少,此后直到收获时,几乎没有变化(Watson等,1958;Cannell,1969).
The tillering stage is one of the most important stages of barley development and has a decisive influence on the yield (Kirby et al., 1972). The number of tillers and the number of tillers depend on the environmental conditions at the tillering stage. The number of tillers per plant is sometimes Reaching the highest value, they began to decrease rapidly before heading, and thereafter there was almost no change until harvest (Watson et al., 1958; Cannell, 1969).
