植物开花是一个很复杂的生理过程,它需要具备多种条件才能完成。矿质元素中的硼对开花有重要的作用,是植物开花不可缺少的条件之一,没有它就会出现“花而不实”的现象。那么硼在开花过程中起什么作用呢?现在已经知道,在植物体的各器官中,硼含量以花中为最多,硼可促进花粉粒的萌发和花粉管的生长。花的各部位中以雌蕊含硼量较多,其中又以柱头和花柱中最多。有人作过分析,花粉中的含硼量仅占雌蕊中含硼量的46％,这是为什么?原来,植物在开花的时候,柱头上的分泌物
Plant flowering is a very complex physiological process, which requires a variety of conditions to complete. Boron mineral elements on the flowering has an important role in the flowering of plants indispensable one of the conditions, without it there will be “flowers and not real” phenomenon. So what is the role of boron in the flowering process? It is now known that in the organs of plants, the content of boron is the largest among the flowers, while boron promotes the germination of pollen grains and the growth of pollen tubes. In various parts of the flower, the amount of boron in the pistil is more, of which the stigma and the style are the most abundant. Someone made an analysis of the amount of boron in pollen, accounting for only 46% of the pistil content of boron, which is why? It turned out that when plants flowering, stigma secretion
