摘要: [目的]研究旨在了解莽山茶区13个野生茶树单株的优势组分,从而根据育种目标进行大量培育繁殖,为莽山茶区选育新的适制性强的专属优良品种奠定基础。[方法]通过对13个莽山茶区野生茶树单株表型性状的观测统计,以及运用紫外分光光度计法、全自动氨基酸分析仪和HPLC法测定其内含成分中水浸出物、可溶性糖、游离氨基酸、茶多酚含量以及儿茶素组分、氨基酸组分。[结果]结果表明13个试样内含成分总体表现为高水浸出物、高可溶性糖、高茶多酚、低氨基酸、低酚氨比。[结论]推测其中一个资源有望成为红茶适制性品种,四个有望成为绿茶适制性品种,尤其以MS-9单株茶多酚和茶氨酸含量均较高,推测其为提取茶多酚和茶氨酸的特异性优质资源。

Abstract: The paper aims to find out the dominant components of 13 wild tea plants in Mangshan tea region for large quantity of cultivation and propagation according to the breeding objectives, and lay a foundation for breeding new varieties of tea plants with strong adaptability. By observing the phenotypic characters of the 13 samples and using UV spectrophotometer method, automatic amino acid analyzer and high performance liquid chromatography (HPLC), we determined the contents of water extracts, soluble sugar, free amino acids, tea polyphenols and catechins. The results showed that: the 13 samples contained high water extract, high soluble sugar, high tea polyphenol, low amino acid and low phenol ammonia ratio. It is speculated that one of the resources is expected to be suitable for black tea and four for green tea, especially MS- 9 tea has high polyphenols and theanine which could be a special and high quality resource for the extraction of tea polyphenols and theanine.
