摘要：

通过对同一环境内生长的100株江华苦茶群体品种单株进行一年三季的基本生化成分分析。结果表明:江华苦茶资源整体表现为一个优质的试制红茶的茶树资源。基本生化成分的季节性表现为春季氨基酸及茶氨酸含量最高,水浸出物、茶多酚和含量为三季最低;秋季茶多酚含量为三季之最,其余各生化成分表现居中;夏季水浸出物和生物碱含量为三季最高,氨基酸及茶氨酸含量最低。同时对三季基本生化成分进行显著性差异分析,结果表明:在水浸出物、咖啡碱、茶氨酸方面春季资源与夏秋季间存在显著差异;在茶多酚方面秋季与春夏季间存在显著差异;在氨基酸、可可碱、酚氨比方面春、夏、秋三季间存在着显著差异。

摘要：

100 individuals of Camellia sinensis var. assamica cv. Jianghua within the same environment were used as materials to analyze the basic biochemical composition of the monoclonal in summer,autumn and winter,to explore the seasonal variations of the basic biochemical composition of tea. The results showed that,Camellia sinensis var. assamica cv. Jianghua was top quality tea germplasm. The amino acid content and theanine content in spring tea were the highest and water extracts,tea polyphenol content and alkaloid content in spring tea were the lowest; The tea polyphenol content was the highest. The water extracts and alkaloid in summer tea were the highest and the amino acid content and theanine were lowest. The significant difference analysis results showed that,the water extract,caffeine,theanine between autumn tea and spring and summer tea had significant differences. The tea polyphenol between autumn tea polyphenols and spring and summer had significant differences. The amino acids,theobromine,phenol ammonia among spring,summer and autumn tea had significant differences.
