| Zusammenfassung: | Copyright © 2016 Elsevier Masson SAS. All rights reserved. Tea [Camellia sinensis (L.)], is an aluminum (Al(3+)) hyperaccumulator plant and grows well in acid soils. In the present study, roots of two tea cultivars, JHC and YS were treated with different concentrations of Al(3+). After treatments, the root length, dry matter, root activity and chlorophyll content (SPAD value) of JHC had greater increase than that of YS. We also detected metabolic changes of two varieties using GC-MS method. Comparison between two cultivars indicated that shikimic pathway was more enhanced in YS roots by Al(3+) with higher levels of catechine, quinic acid and shikimic acid. While, more active amino acid synthesis was found in JHC roots and JHC leaves remained the higher level contents of metabolites related to cysteine synthesis. The comparison also showed that a large amount of sugar alcohols were accumulated in roots of two varieties, whereas most of them were reduced in YS leaves. Other well-known ligands, such as phosphoric acid and malic acid were observed in two cultivars that showed significantly altered abundances under Al(3+) treatments. The results indicated that Al(3+) adaptation of two cultivars may be correlated with their differential metabolism of amino acids, sugars and shikimic acids |
