| 摘 要： | 研究结果表明,优选1号、6号、11号、13号等4个杂交选育的高咖啡碱品种属小乔木,大叶种,树姿半开张,生长势强、萌芽早,芽叶粗壮,色泽黄绿,多茸毛,产量特高,比云南大叶种高62%以上,移植成活率达97%以上,栽培适应性强;一芽二叶生化成分含量丰富,咖啡碱、茶多酚、儿茶素、氨基酸及水浸出物均高于云南大叶种,其中咖啡碱含量尤为特出,春茶达5.11%～6.15%,比对照种高25.86%～51.47%,生化变化规律,咖啡碱、氨基酸含量春茶夏茶秋茶,茶多酚、儿茶素、水浸出物含量夏茶秋茶春茶,适制高档红茶。滋味浓强鲜爽,汤色红艳,香气高爽,部分品种花香明显,其品质表现与生化物质含量相吻合。高咖啡碱茶树品种的育成为开发天然植物咖啡碱,茶树资源多用途开发提供了新的途径。

| Abstract: | Study shows that the breeding of hybrid varieties of high-caffeine was Small tree, and Belongs large-leaved species. The production than large-leaved species in Yunnan high above 62%, the transplant survival rate more than 97%,and the cultivation adaptability was very high. the caffeine content was 5.11%～6.15%, It compared to compares high 25.86%～51.47% .The high caffeine tea tree variety nurtured into the development natural plant caffeine, the tea tree resources multipurpose development has provided the new way. |
