该文研究了茶树品种对红茶茶汤色素含量、色差值L*、a*、b*的影响。结果表明TF、TR、TB含量与L*、a*、b*之间呈显著相关;不同采摘标准下色素含量为一芽二叶>一芽三叶,色差值a*、b*为一芽二叶>一芽三叶,L*为一芽三叶>一芽二叶,且其差值随品种而异,采摘标准不当可掩盖品种的品质潜力;基于鲜叶中茶多酚量(GTP)、茶多酚消耗量/鲜叶中茶多酚量(CTP/GTP)、色素生成量/茶多酚消耗量(GP/CTP)三个指标,六个茶树品种可被分为四组,分别为高GTP低CTP/GTP低GP/CTP品种,如凤庆3号;低GTP高CTP/GTP低GP/CTP品种,如梅占;GTP、CTP/GTP、GP/CTP同时高(或低)品种,如云抗10号、凤庆9号、清水3号;高GTP低CTP/GTP低GP/CTP品种,如群体种。其中群体种GP/CTP最高而CTP/GTP极低,且成品茶茶汤具有高a*、b*值、低L*值,表现出极佳的红茶适制性。通过选择适当的茶树品种与采摘标准可保证成品红茶的优质。
該文研究瞭茶樹品種對紅茶茶湯色素含量、色差值L*、a*、b*的影響。結果錶明TF、TR、TB含量與L*、a*、b*之間呈顯著相關;不同採摘標準下色素含量為一芽二葉>一芽三葉,色差值a*、b*為一芽二葉>一芽三葉,L*為一芽三葉>一芽二葉,且其差值隨品種而異,採摘標準不噹可掩蓋品種的品質潛力;基于鮮葉中茶多酚量(GTP)、茶多酚消耗量/鮮葉中茶多酚量(CTP/GTP)、色素生成量/茶多酚消耗量(GP/CTP)三箇指標,六箇茶樹品種可被分為四組,分彆為高GTP低CTP/GTP低GP/CTP品種,如鳳慶3號;低GTP高CTP/GTP低GP/CTP品種,如梅佔;GTP、CTP/GTP、GP/CTP同時高(或低)品種,如雲抗10號、鳳慶9號、清水3號;高GTP低CTP/GTP低GP/CTP品種,如群體種。其中群體種GP/CTP最高而CTP/GTP極低,且成品茶茶湯具有高a*、b*值、低L*值,錶現齣極佳的紅茶適製性。通過選擇適噹的茶樹品種與採摘標準可保證成品紅茶的優質。

Effects of varieties on the content of tea pigment, L*, a* and b* value of chromatic aberration of black tea infusion was studied. The correlation relationship between content of TF, TR, TB and L*, a*, b* value was extremely significant at P<0.05. Fresh tea leaves with plucking standard of 1 bud and 2 leaves could man-ufacture black tea with higher content of tea pigment, higher a* and b* value but lower L* value, than those of plucking standard of 1 bud and 3 leaves. But the discrepancy of certain parameter of the two plucking standards changed with vari-eties. Varieties’ quality potential could be concealed by improper plucking standards. Six varieties were divided into four groups on the basis of gross tea polyphenols in fresh tea leaves (GTP), consumption of tea polyphenols to gross tea polyphenols ratio (CTP/GTP) and gross tea pigment to consumption of tea polyphenols ratio (GP/CTP). Hybrid performed the very suitability of black tea manufacturing. To en-sure high quality of made black tea, suitable variety should be chosen and reason-able plucking standard also should be taken into consideration.
