光照对柿树结果及果实品质的影响

The Influence of the Sunlight on the Fruiting and the Fruit Quality in Persimmon Trees

以磨盘柿为试材对光照与柿树结果的关系进行了研究,结果表明:光照强度与结果母枝及结果枝数量成正比,与长度成反比,与果实数、总产量、单果重、果实横径及果实中可溶性固形物含量成正比,而与着色无显著相关。

The results of this study on th relationship between the sunlight and the fruiting of persimmon trees(Diospyros kaki L.)are summarised as follows: 1.The number of the mother bearing branch and the number of the fruiting branch are in direct proportion to the sunlight intensity,but the lengh of these two kinds of branchs is in inverse proportion to the sunlight intensity. 2.The number of fruit,total output,the weight of average fruit, the transverse diameter of fruit,and the soluble solids content of fruit are in direct proportion to the sunlight intensity,but the colouring of the fruit is out of proportion to the sunlight intensity.
