摘　　要：从2021年开始,项目组连续三年对安吉‘白叶1号’捐苗种植地的贵州普安、雷山、沿河,湖南古丈,四川青川三省五县和安吉原产地的茶树生长习性和品质进行跟踪研究。本文总结2023年春浙江、贵州和湖南茶鲜叶品质主要成分,按安吉白茶采摘标准采一芽二叶,分析了鲜叶中水浸出物等主要理化成分的含量以及异地生长的‘白叶1号’茶鲜叶品质差异。结果显示,2023年春茶‘白叶1号’异地与原产地鲜叶理化成分在水浸出物、游离氨基酸和茶氨酸含量方面存在显著性差异,原产地的水浸出物总量>42%,游离氨基酸含量>4.5%,茶氨酸含量>2.5%;茶苗受捐地水浸出物含量>37%,游离氨基酸含量>5.5%,茶氨酸含量>3.0%;非基地水浸出物含量>36%,游离氨基酸含量>4.0%,茶氨酸含量>1.5%。Since 2021,the growth habits of tea cultivar‘Baiye 1’and it tea quality grown in various tea areas including Puan,Leishan,Yanhe in Guizhou,Guzhang in Hunan,Qingchuan in Sichuan were tracked and investigated for three consecutive years,with that grown in Anji,its origin area,for control.This paper summarizes the comparative study of the main quality related components in spring tea leaves in Zhejiang,Guizhou and Hunan in 2023.According to the picking standard of"Anji Baicha",shoots with two leaves and a bud were collected and major quality related indicators including water soluble extracts and chemical components were determined.The results showed that the physical and chemical components such as water soluble extracts,total free amino acids and theanine content in fresh leaves of spring shoots in 2023 were significantly different among various producing areas as compared to Anji.The content of water soluble extracts was more than 42%in Anji,with free amino acids more than 4.5%,and theanine content more than 2.5%.The content of water soluble extracts in the other areas was more than 37%,with free amino acids more than 5.5%and theanine content more than 3.0%.The content of water soluble extracts in teas grown in non-base areas was more than 36%,with total free amino acids more than 4.0%and theanine content more than 1.5%.
