| Abstract: | The relationship between contents of free amino acids in tea shoots and resistance of tea varieties to tea pink mite Acaphylla theae Watt was investigated. The total free amino acid contents, especially the theaine (Thea), glutamic acid (Glu) ,alanine (Ala), glycine (Gly), asparatic acid (Asp), serine(Ser) and valine(Val), etc. in resistant varieties, were significantly higher than those in susceptible varieties. The average activities of glutamin dehydrogenase (GDH) and pheny-lalanine ammonia lyase (PAL) in the former were 2.3 and 3.2 times as many as those in the latter, respectively. Bioassay results showed that each/total of the amino acids mentioned above had inhibited the feeding behavior and reproduction of this mite. The contents of amino acids got from leaf surface of resistant varieties by water rinsing were more than those of susceptible ones. It was suggested that the resistance of tea tree to this mite might be increased after the content of free amino acid in tea shoot had enhanced by rational application of nitrogen fertilizer. |
