摘　　要：采摘绥阳县贵州芸清湘茶旅养综合开发有限公司茶园种植的黄金叶、白叶1号茶树的一芽二叶,以福鼎大白茶一芽二叶为对照,对遵义地区引进的黄金叶和白叶1号茶树品种进行化学功能成分研究,分析2个品种在遵义种植的可行性。结果表明,黄金叶和白叶1号水浸出物含量与福鼎大白茶没有显著差异;总灰分和花黄素高于福鼎大白茶;茶多酚和咖啡碱含量低于福鼎大白茶;游离氨基酸总量表现为白叶1号显著高于福鼎大白茶,而黄金叶与福鼎大白茶没有显著差异。黄金叶、白叶1号的鲜爽甜味氨基酸在总游离氨基酸中占比低于福鼎大白茶,苦味氨基酸在游离氨基酸中占比大于福鼎大白茶,而人体必需氨基酸含量较高的是白叶1号。化学功能成分分析表明,遵义地区引进黄金叶和白叶1号种植没有降低其高品质的特点,可生产优质绿茶,适合在遵义地区种植。One bud and two leaves of tea trees in spring in tea garden of Guizhou Yunqingxiang Tea,Tourism and Health Comprehensive Development Co.,Ltd.in Suiyang County were used as materials,and Fuding Dabaicha was used as control.The chemical functional components of Huangjinye and Baicha No.1 introduced from Zunyi were studied to analyze the feasibility of planting the two varieties in Zunyi.The results showed that there was no significant difference between the water extract contents of Huangjinye and Baiye No.1 and Fuding Dabaicha.Total ashe and anthoxanthin were higher than that of Fuding Dabaicha.Tea polyphenols and caffeine contents were lower than that of Fuding Dabaicha.The total free amino acid content of Baiye No.1 was significantly higher than that of Fuding Dabaicha,while the free amino acid content of Huangjinye was not significantly different from that of Fuding Dabaicha.The proportion of fresh sweet amino acids in total free amino acids of Baiye No.1 was lower than that of Fuding Dabaicha,and the proportion of bitter amino acids in total free amino acids was higher than that of Fuding Dabaicha,while Baiye No.1 had higher essential amino acids content.The analysis of chemical functional components showed that the introduction of Huangjinye and Baiye No.1 planting in Zunyi area did not reduce its high quality characteristics,and it could produce high quality green tea,which was suitable for planting in Zunyi area.
