【摘要】 通过对茶树留养叶光合速率与新梢生育、采摘、打顶、花蕾发育,以及留养叶的着生部位等关系的研究,结果表明,留养叶的光合速率随新梢生育而回升,在新梢长到1芽2叶时达到高峰,采摘能促进新梢萌发,扩大库容量,发挥留养叶的光合潜力,但休止前打顶会降低留养叶的光合效率;采摘时留养鱼叶的光合功能与正常叶相近,留2叶与留1叶光合源能力相近,主梢留叶比侧梢留叶光合能力强;着蕾可提高留养叶的光合速率,着蕾越多,增加越大。更多还原

【Abstract】 Relations among the photosynthetic rate of maintenance foliage and developmentof the new-buds and flower-buds,the plucking and toping of a shoot,the position ofthe maintenance foliage on the tea plant were studied.The photosynthetic rate ofmaintenance foliage rises with the germinating of the bud and growing of the shoot.There is the highest photosynthetic rate in two and a bud stage.The plucking makesphotosynthetic rate rises because the germination of the new-bud is stimulated.Thephotosynthetic rate of leaves decreases after the main shoot bud is plucked before beingdormant.The photosynthetic rate of the fish leaf is similar to the normal leaf.Thecapacity of the photosynthetic soures of left leaves is similar between leaving twoleaves and leaving one leaf.The photosynthetic rate is higher in the state whichleaving leaf in the main shoot than leaving leaf in the lateral shoot.The photosynthticrate of the leaf rises as the flower-buds grow,the more they grow,the more it rises.更多还原
