在相同生态、栽培条件下,对相同树龄的福建省40个通过国家、省级审(认、鉴)定的茶树品种进行连续2年的春梢物候期调查、生化成分检测及遗传多样性分析。结果表明,在26个乌龙茶品种中,31%为早生种,46%为中生或中晚生种,23%为晚生种;在14个绿茶品种中,29%为特早生种,7%为晚生种,其余64%为早生或中生种;各品种间存在显著的芽期差异,为生产用种芽期搭配提供了有利条件。参试品种的水浸出物含量为40%~52%,茶多酚9.8%~20.8%,游离氨基酸3.0%~6.8%,咖啡碱2.9%~5.0%,说明各成分含量在品种间具有较大差异。参试的40个品种遗传多样性较丰富,其中早春毫、政和大白茶、霞浦元宵茶和悦茗香4个品种的遗传距离较远,其他36个品种聚类可分为铁观音类群、闽南类群、福鼎大白茶类群和黄旦类群等4类。本研究结果为茶叶生产用种的多样性选择提供了重要的数据参考和理论指导。
在相同生態、栽培條件下,對相同樹齡的福建省40箇通過國傢、省級審(認、鑒)定的茶樹品種進行連續2年的春梢物候期調查、生化成分檢測及遺傳多樣性分析。結果錶明,在26箇烏龍茶品種中,31%為早生種,46%為中生或中晚生種,23%為晚生種;在14箇綠茶品種中,29%為特早生種,7%為晚生種,其餘64%為早生或中生種;各品種間存在顯著的芽期差異,為生產用種芽期搭配提供瞭有利條件。參試品種的水浸齣物含量為40%~52%,茶多酚9.8%~20.8%,遊離氨基痠3.0%~6.8%,咖啡堿2.9%~5.0%,說明各成分含量在品種間具有較大差異。參試的40箇品種遺傳多樣性較豐富,其中早春毫、政和大白茶、霞浦元宵茶和悅茗香4箇品種的遺傳距離較遠,其他36箇品種聚類可分為鐵觀音類群、閩南類群、福鼎大白茶類群和黃旦類群等4類。本研究結果為茶葉生產用種的多樣性選擇提供瞭重要的數據參攷和理論指導。

The spring phenophase, biochemical composition and genetic diversity analysis of the 40 tea cultivars with same age, which passed the national and provincial examination or approval from Fujian, were surveyed and identified under the same ecological and cultural condition for two years. The results showed that among the 26 tested oolong tea cultivars, 31% of those were early sprouting cultivars, 23% were late sprouting cultivars and 46%were medium or medium-late sprouting cultivars, among the tested 14 green tea cultivars, 29% of those were extra-early sprouting cultivars, 7% were late sprouting cultivars, and the rest 64% were early or medium sprouting cultivars. Significant differences on bud stage among tea cultivars provided a strong basis for reasonable collocation on bud stage in production. In the tested cultivars, water extracts was from 40%to 52%, tea polyphenols from 9.8%to 20.8%, free amino acids from 3% to 6.8%, and caffeine from 2.9% to 5.0%. The results showed that the contents of each biochemical component among different cultivars had a relatively significant difference. The genetic diversity of tested cultivars was relatively higher, genetic distances of Zaochunhao, Zhenghe-dabaicha, Xiapu-yuanxiaocha, and Yuemingxiang were relatively farther away, and the rest 36 cultivars could be divided into 4 main groups:Tieguanyin type, Minnan type, Fuding-dabaicha type, and Huangdan type. This study provided important data reference and theoretical guidance for diversity of choice in production cultivars.
