摘要
Abstract
[Objective] The regularity of net photosynthesis rate of Pingguoli leaves was studied,and the causes of midday rest phenomenon of Pingguoli were analyzed.[Method] Pingguoli tree in Yanbian area was chosen as the material to study all kinds of photosynthesis parameter of Pingguoli leaves using LCi portable photosynthesis system which was produced in Britain.[Result] On the sunny day during growth season,Pn of Pingguoli leaves showed bimodal curve in day variation and annual variation which had the obvious midday rest phenomenon in summer.The daily variation regularity of Pn was similar with those of the one year news shoots,the non-fruit short shoots and bear fruit short shoots.[Conclusion] Pn of Pingguoli kept at a relatively higher value from July to September.Fruits could promote photosynthesis of leaves.Pn value of bear fruit short shoots was higher than those of one year new shoots and non-fruit short shoots from July to September.关键词
