叶面喷施氨基酸对茶叶中γ-氨基丁酸含量的影响

doi:10.13305/j.cnki.jts.2006.04.001

Abstract

Abstract: Vacuum and anaerobic treated fresh tea leaves which sprayed by different kind or concentration of amino acid were investigation. The influence on theγ-aminobutyric acid (GABA) biosynthesis by different treatments were analyzed. The result showed that the content ofγ-aminobutyric acid was enhanced obviously after foliage-sprayed and vacuum treatment. The influence of six types of amino acid on the ability ofγ-aminobutyric acid biosynthesis was Glutamic Acid>Asparticacid>Glutamine>Phenylalanine>Glycine>Alanine. The content of Glutamic acid, Aspartic acid and Thenine in tea fresh leaves may be the criterion of synthesizing ability forγ-aminobutyric acid. The total content of Glutamic acid, Aspartic acid and theanine has reached the peak on the fifth day in tea fresh leaves. 0.5% Glutamic acid sprayed on tea leaves for 5 days is the best method.

Key words: tea, γ-Aminobutyric acid;, amino acid foliage spray, glutamic acid
