摘要

白化现象在植物界普遍存在,茶叶作为一种叶用植物,白化变异植株中关键化学成分如叶绿素、类胡萝卜素、儿茶素类、氨基酸类、黄酮类等物质含量发生了显著变化,这些变化对茶树生长发育、抗逆性、茶叶制作工艺、口感等有重要影响。叶色变异作为一种突变性状对于茶树新品种选育有着重要的应用价值,对研究茶树光合作用机制、叶色调控机理、叶片发育调控等也有重要理论价值。本文综述了国内近几年关于茶树白化突变体化学成分叶绿素、类胡萝卜素、氨基酸、儿茶素的研究及茶树白化突变分子机制的研究进展,旨在为茶树白化突变体分子机制的深入研究提供参考。

Abstract

Leaf albino is a common phenomenon in the plant kingdom. As a kind of leaf-used plant, the key chemical ingredients in albino tea cultivars such as chlorophyll, carotenoids, catechins, amino acids, flavonoids are significantly changed as compared with normal tea cultivars, which largely affect the growth, stress resistances, production process and taste of tea. Leaf color mutation, as a special mutation, has important application value for tea breeding. It is also useful for our understanding of the photosynthesis system, the regulation mechanism of leaf color and the regulation of leaf development in tea plants. This article reviewed the research progress on the chemical compositions such as chlorophyll, carotenoids, amino acids and the mechanism of the mutation in the albino tea cultivars, which aimed to provide a foundation for further study of the molecular mechanism in albino tea cultivars.

Key words： tea plant (Camellia sinensis (L.) O. Kuntze); albino variation; review
