我们可以做这祥的试验:把一个枝条基部的果实都去掉,使其在上部结果,第二年可以看到该枝条上部成花不到1％,下部没结果的枝段成花也不到1％;相反,如果把枝条顶部的果实去掉,让基部结果,则第二年该枝条上部芽有80％成花,基部有20％成花。可见,枝条顶部的果实可以抑制其基部成花,而基部的果实并不抑制上部的花芽形成。如果进一步试验,在枝的中部进行环 We can do this auspicious test: to remove the fruits of the base of a branch, so that in the upper results, the next year you can see the upper part of the branches into less than 1% of the flowers, the lower branches of the results did not result in less than 1% ; On the contrary, if the top of the branches of the fruit is removed, so that the base results, the next year the branches of buds 80% into flowers, the base of 20% into flowers. Visible, the top of the branches of the fruit can inhibit the base into flowers, and the base of the fruit does not inhibit the formation of the upper flower buds. If further testing is carried out, the ring is made in the middle of the branches
