Self pollination and fruit setting of fruit trees

With the flowers, and the same cross between monoecious cultivars with different pollination between plants called self pollination. The most typical self pollination is that the pollen grains are mature before the flowers are in bloom, and the process of pollination is completed in the same flower. In the case of some grape varieties, the anthers have been cracked before the cap is off. Self pollination can be fertilized by a strong, known as the self - strong, since the flower - bearing fruit trees have full flower. The most common development of male and female, such as grape, peach, apricot varieties, part of the cherry, plum varieties. Since the phenomenon of self pollination can not be the result of self - flower is not strong. Most of the apple, pear, cherry, peach and plum cultivars, self pollination rate is very low, need cross pollination production. Self pollination but cannot produce viable seeds phenomenon called self sterility, such as grape, self pollination, but the seed abortion.
