果树的产量与果实的品质,除决定于各种栽培管理措施外,是否有良好的授粉树,能否顺利完成授粉、受精过程也是一个十分重要的因素。大多数果树,特别是仁果类的果树通常是自花不实或微量结实的,即栽植单一品种的果树是不会有经济产量的。但自花结实的树种配置不同品种的授粉树后,也可显著增产。影响授粉受精的因素很多,主要有以下几方面。 (一)亲和力首先要考虑授粉品种与主栽品种要有良好的亲和力。花粉落到柱头上后,要经过二者的互相识别和选择,并非落到柱头上的花粉都能萌发。如果二者亲合,花粉吸水膨 Fruit tree yield and fruit quality, in addition to a variety of cultivation and management measures, whether there is a good pollination tree, can successfully complete the pollination, fertilization process is also a very important factor. The fruit trees of most fruit trees, especially pomes, are usually self-primed or traceable, meaning that there is no economic yield for planting a single variety of fruit trees. However, self-pruned tree species with different varieties of pollination trees can also be significantly increased. There are many factors that affect pollination and fertilization, mainly in the following aspects. (A) Affinity Must first consider the varieties of pollination should have good affinity with the main cultivars. Pollen fell to the stigma, to go through the mutual recognition and choice between the two, not falling on the stigma of pollen germination. If the two affinity, pollen absorbent swelling
