青梅树叶片某些光合性能的研究

STUDIES ON SOME PHOTOSYNTHETIC CHARACTERISTICS IN LEAVES OF MEI TREE (PPRUNUS MUME)

  • 摘要: 六月上旬检测青梅树叶片光合作用对光照强度的反应、光合速率的日变化及其影响因素,表明青梅树叶片光合作用的光补偿点和光饱和点分别为2-3千勒克斯和35-40千勒克斯。在新梢旺盛生长期的晴天。叶片的光合速率于10时和15时出现两次高峰。叶片的光合生产能力直接受光照强度的制约,同时还受气温和空气相对湿度的影响。

     

    Abstract: Photosynthetic reactions by intensity of the sunlight, photosynthesis rate in a whole fine day and its affected factors were detected on leaves of Mei tree (Prunus mume) in early June, 1983 and 1984. The results showed that the light compensation point and light saturation point of Mei tree's leaves are 2-3klx and 30-40klx, respectively. Photosynthesis rate of the leaves reaches two peaks at 10 and 15 hour in a fine day during the growing season. Photosynthetic productivity of the leaves is affected by temperature and relative humidity of air as well as directly constrained by intensity of the sunlight.
