茶树(Camellia sinensis)为多年生叶用植物,其叶色变异具有易观察、易鉴别、易利用的特点,对茶树新品种选育和改良具有重要的参考价值;叶色变异茶树是研究叶绿素代谢途径和发育调控、叶片呈色机理以及鲜叶适制性等的理想材料。茶树的特征性化学成分茶多酚、氨基酸、色素类物质(叶绿素和类胡萝卜素)等在叶色变异茶树中的含量均会发生显著变化,这些变化对茶树光合作用、抗逆性、鲜叶适制性、成茶品质有重要影响。研究表明,茶树叶色变异的发生与色素类物质合成降解、叶绿体发育、核-质信号转导等因素密切相关。本文主要从茶树叶色变异分类、重要化学成分变化、影响叶色变异的环境因素及分子机制等方...

Tea plant (Camellia sinensis) is a kind of perennial leaf-used plant. Its phenotypic variation of leaf color has characteristics in observation, identification and utilization, which is of great value to breeding and improvement of new varieties. Besides, it is also the ideal material for researching chlorophyll metabolic pathway, regulation mechanism of chloroplast development and leaves coloration, as well as the adaptability of fresh tea leaves. The contents of characteristic chemical components in tea plant, such as polyphenols, amino acids...
