摘要: 以安吉白茶和智仁早茶为实验材料,营养液栽培条件下,研究不同铝氟浓度交互处理对茶叶品质的影响,30 d后测定茶多酚、咖啡碱等主要品质成分的含量。结果表明,单铝处理时,随着铝(30 mg/L)加入,茶多酚、咖啡碱、氨基酸、维生素C和叶绿素含量均上升,当铝浓度增加到90 mg/L,含量却下降;单氟处理时,茶叶品质的主要成分均表现为低浓度(4 mg/L)的促进生成和高浓度(12 mg/L)的抑制产生;铝氟交互作用下,在铝氟比例分别为30/4、30/12和90/4、90/12两个过程中,安吉白茶鲜叶中各品质成分含量均呈现上升趋势,表现为协同作用,而智仁早茶呈现下降趋势,拮抗对方的促进效应。结果说明,茶叶在低浓度的铝、氟时表现出较好的品质,而铝和氟的不同交互比例产生不同程度的交互效应,减弱本身毒性,且安吉白茶和智仁早茶之间的不一致现象,体现品种之间存在差异。

Abstract: In this research, quality of tea leaves to aluminum (Al) and fluorine (F) interaction were studied, and five indices (polyphenols, caffeine, free amino acids, vitamin C and chlorophyll concentrations) in tea leaves (variety Anji Baicha and zhirenzaocha) were investigated after 30 d in hydroponic culture. The nutrient solution was treated by the interaction of Al (0, 30, 90 mg/L) and F (0, 4, 12 mg/L). The results were summarized as follows: With 30 mg/L of the single Al, the contents of polyphenols, caffine, free amino acids, vitamin C and chlorophyll in tea leaves were increased. But when the concentration of Al was 90 mg/L, the contents of above components in tea leaves were decreased. These components in tea leaves were increased under the treatment of 4 mg/L of the single F and decreased with the treatment of 12 mg/L of the single F. In the process of aluminum and fluorine interaction, the contents of these components in tea leaves of Anji Baicha were increased during the treatments of Al/F ratioin 30/4, 30/12, 90/4 and 90/12. However, zhirenzaocha were decreased. The results showed that tea quality improved in low concentration of aluminum or fluorine. Meanwhile, the variance effect of interaction was correlated to different proportion of Al/F and the proportion of Al/F for better quality of Anji Baicha and zhirenzaocha was different indicating there existed a varietal difference.
