【摘要】 以江西省铅山县主栽并主产的河红茶的品种福鼎大白茶为对照，研究了从浙江、福建引进江西的国家级茶树良种中茶108、金观音的河红茶适制性和制茶品质。结果表明：中茶108、金观音的春、夏、秋季鲜叶的水浸出物含量范围为42.09%～46.10%，氨基酸含量范围为3.07%～4.91%，茶多酚含量范围为24.53%～29.60%，均显著高于对照福鼎大白茶；酚氨比（茶多酚与氨基酸的比值）范围为5.42～9.65，也高于对照福鼎大白茶，具有红茶适制性；所制红茶内含物丰富，其特征成分氨基酸含量范围为2.90%～3.96%，茶多酚含量范围为15.51%～26.48%；茶汤的茶黄素、茶红素含量均较高，分别为0.54%～0.74%、6.85%～9.03%，且茶红素/茶黄素范围为10.98～12.65，因此其具有滋味浓强、汤色红亮的物质基础。感官评价结果显示，引进的2个品种所制红茶品质较优异且相当，均优于对照福鼎大白茶所制红茶的品质。更多还原

【Abstract】 The Fudingdabaicha, a dominant cultivar mainly used for producing black tea in Yanshan County, was taken as the control. The suitability for processing black tea of the state-level excellent tea cultivars Zhongcha 108 and Jinguanyin which were introduced from Zhejiang Province and Fujian Province to Yanshan County, Jiangxi Province was studied. The results showed that spring and summer shoots of two cultivars contained abundant water soluble substances(42.09%～46.10%),amino acids(3.07%～4.91%) and tea polyphenols(24.53%～29.60%), which were higher than those of the control. The ratio of polyphenols to amino acids ranged from 5.42 to 9.65, which was higher than that of the control, suggesting that both introduced cultivars are suitable for processing black tea. Black tea produced from the two cultivars contained abundant quantities of internal substance with characteristic components including amino acids(3.07%～4.91%) and tea polyphenols(15.51%～26.48%).Moreover, the contents of theaflavins(TFs) and thearubigins(TRs) in the tea infusions were high, ranging from 0.54% to 0.74%and from 6.85% to 9.03%, respectively, and the ratio of TR to TF ranged from 10.98 to 12.65, providing the material basis for the strong taste and red color of tea infusion. The sensory quality of Zhongcha 108 was similar to that of Jinguanyin, and both were significantly better than Fudingdabaicha.更多还原
