天然无咖啡碱茶叶资源的开发利用研究

Studies on Natural Non Caffeine Tea Resources

以天然无咖啡碱南昆山毛叶茶为材料，通过染色体数目和组型分析，证明其是一种进化程度较高的乔木型、大叶类茶树；生物碱组成和含量的单株测定结果表明：南昆山毛叶茶在有性群体品种中低咖啡碱含量单株比例可达 81.82％；低咖啡碱单株的理化成分与一般茶树品种没有显著差异。

Nankun shan tea leaf variety was a world rare tea resource not containing caffeine.The chromosome number and karyotype analysis showed that it was a kind of evolutionary arboreous macrophyllous tea phant.In the variety,81.82％ of the single plant were non－ caffeine or of low caffeine content. But the rest biochemical compositions besides alkaloid were of no greater shan different than the high caffeine content plant.
