近年来依照植物阶段发育的理论,由于一系列的研究确定了,在不同发育阶段(Этап)植物对于光线强度的需要是不一样的。我们用大麦的工作曾指出,从穗中部花的花药中花粉母细胞的四分体形成时开始,降低光缐强度延迟植株抽穗5天及引
In recent years, according to the theory of plant stage development, due to a series of studies, the light intensity needs of plants at different developmental stages are not the same. Our work with barley has pointed out that starting from the time of tetrad formation of pollen mother cells in the anthers of the mid-spike, the light intensity is reduced to delay plant heading for 5 days
