摘要为了探究氟铝交互处理对茶叶主要化学成分的影响,以福建水仙茶苗为试验材料,不同浓度下氟铝交互处理水培30 d后,测定茶苗嫩叶和老叶（成熟叶片）中茶多酚、氨基酸、、黄酮和水浸出物含量.结果表明：老叶和嫩叶在氟铝交互处理下,茶多酚、氨基酸、黄酮、、水浸出物等成分含量呈现一定的规律性.在高氟处理（12 mg/L）下,随着铝的加入,老叶茶多酚、老叶含量和嫩叶水浸出物,B4>C4>D4,逐渐降低；老叶氨基酸和老叶水浸出物含量,B4D3>D4,逐渐降低.黄酮含量的变化则未发现明显的规律.铝和氟的不同交互比例处理产生不同程度的交互效应,氟铝交互处理对茶树叶片中主要化学成分含量影响差异显著.

Abstract In order to explore the influence of interaction of aluminum（Al）and fluorine（F）on the main chemical components of tea, Fujian Shuixian tea seedlings were used as the test materials, and five indices（polyphenols, caffeine, free amino acids, flavonoids and water extracts concentrations）in tender and old leaves were investigated after 30 d in hydroponic culture. The results showed as the follows： In the process of aluminum and fluorine interaction, the contents of above components in tender and old leaves showed a certain regularity. In the treatment of high fluoride（12 mg/L）with the addition of aluminum, the content of polyphenol and caffeine in old leaves, water extract in tender leaves was in the order B4>C4>D4, and the content of amino acid and water extract in old leaves was in the order B4D3>D4. The rule of flavonoids chang was not obvious. The variance effect of interaction was correlated to different proportion of A1/F, the effect of aluminum fluoride interaction on the contents of main chemical components in tea leaves was significantly different.

氟、鋁是茶树中2种特殊的元素,在茶树中的含量水平远远超过其他植物.茶树具有很强的氟、铝积累能力,被称为富氟植物、聚铝植物.氟、铝不是茶树生长的必需元素,但能对茶树产生重要影响.有研究表明,茶树氟的累积是以F/Al络合形态存在[1],氟可能和铝等金属元素、细胞壁中淀粉酶和蛋白质生物大分子等以特定的比例络合形式存在[2],再吸收运转到叶片特别是成熟叶片中.目前已有不少学者对氟铝单因素对茶叶化学成分的影响进行相关研究.于翠平[3]等研究发现,铝处理增加茶树叶片叶绿素的含量.唐茜[4]等发现,随氟处理浓度增加,叶绿素含量降低,同时氨基酸、儿茶素组分和含量也降低.但氟铝综合研究相对较少,近年来,王小平[5-7]等学者开始将氟铝结合起来,研究氟铝交互处理对茶树生长、生理生化特性、茶叶品质等方面的影响.但尚未见到氟铝交互处理下,对茶树嫩叶和老叶主要化学成分变化规律分别进行研究的报道.本试验通过茶苗水培试验,设计不同浓度下氟铝交互处理组合,分别测定各处理下茶叶嫩叶及老叶主要化学成分含量,分析其含量变化规律,探讨氟铝交互处理对茶叶主要化学成分的影响,为茶树栽培提供一定的科学依据.
