叶片是茶树进行光合作用、蒸腾作用和气体交换的主要营养器官,也是栽培茶树的目的物。叶片的解剖结构是茶树一系列生理活动的基础,与物质代谢有密切的关系,因此,研究茶树不同叶位的解剖结构及其变化规律,具有重要意义。一般红绿茶的采摘标准,是当新梢长至一芽三叶时,采一芽二、三叶。笔者于今年春季,当福鼎大白茶(11足龄)春梢长至一芽三叶时,取芽下第一叶、第二叶、第三叶、鱼叶,和去年秋梢第一叶、第二叶、第三叶。经石蜡切片后,在光学显微镜下进行观察研究。现将观察研究的初步结果整理成文,供参考。 The leaves are the main vegetative organs of photosynthesis, transpiration and gas exchange in tea plants, and are also the objects of tea tree cultivation. The anatomical structure of leaves is the basis of a series of physiological activities of tea tree, which is closely related to the metabolism of the material. Therefore, it is of great significance to study the anatomical structure and its variation of tea leaves at different leaf positions. General red and green tea picking standards, when the shoots grow to a bud clover, mining a bud two or three leaves. The author in spring of this year, when Fuding big white tea (11 feet old) spring shoots grow to a bud clover, take bud under the first leaf, the second leaf, the third leaf, the leaf, and the first leaf last autumn , The second leaf, the third leaf. After paraffin sectioning, observation was conducted under an optical microscope. Now observe the preliminary results of the study collated, for reference.
