| 摘 要： | 通过测定同一生态环境下生长的31份茶树材料春、夏、秋3季1芽2叶时茶叶的主要生化成分,同时制作烘青茶样进行感官审评,并对测定数据进行统计分析,以揭示影响绿茶品质季节间差异的主要生化因子。结果表明,有27份材料的茶叶品质呈现出春季高于夏、秋季的变化趋势。对27份材料生化成分与品质总分的逐步回归分析、相关分析和通径分析表明,氨基酸、花青素和叶绿素含量对茶叶品质的影响最大,是导致绿茶品质季节间差异的主要生化因子。其中氨基酸表现为正向影响,在季节间呈现春季高、夏秋季降低的规律;花青素和叶绿素表现为负向影响,在季节间呈现春季低、夏秋季升高的趋势。

| Abstract: | In order to find the major biochemical components which affect the green tea quality among different seasons,biochemical components of two leaves and a bud of 31 cultivars in different seasons,which growth at the same ecological field,were analyzed,and basket-fired green teas were processed at the same time for organoleptic evaluation.The results showed that the quality of spring tea of 27 cultivars was better than that of summer and autumn.Stepwise regression analysis,correlation analysis and path analysis... |
