摘要
对核桃光合特性与座果率关系的研究结果表明：相对光强与核桃座果率呈显著正相关（ｒ＝０．９３＊）。核桃叶片的叶绿素含量与光合速率相关显著。同一品种树姿不同的结果枝座果率差异显著。核桃的光饱和点为６０ｋ｜ｘ。不同品种座果率有显著差异。核桃不同部位叶片光合速率差异显著。
In this paper,the photosynthetic characteristics and fruit setting rate of English walnut ( Juglans regia L.) were studied.The main results were:The fruit setting rate was potisively correlated to relative light density.The photosynthetic rate was positively correlated to the content of chlowophyll.There was a significant difference in fruit setting rate of fruitbranch with different tree form.The light saturation point in English walnut was bokix.
