Abstract

The effect of different degrees of drought stress on the aromatic constituents and their relative contents in fresh leaves of Lingtou Dancong tea plants was studied in this paper. The results showed that drought stress could evidently increase the kinds of aromatic components in the fresh leaves. The largest number of kinds (58) of the aromatic constituents was detected when soil relative water content was 53.90%among all the designed treatments, while the lowest number was found under a soil relative water content of 99.75%. The total amount of relative contents of 17 kinds of aromatic components such as linalool etc., increased with drought stress, whereas 12 kinds of aromatic components such as tetradecanoic acid etc., decreased with drought stress. Linalool, linalool oxide, tetradecane, 10-methylnonadecane, and dodecanal showed high contents under the soil relative water content of 53.90%; Cyclohexane, 1-hexadecene, and 1tricosanolonly were induced in the soil relative water content of 53.90% and 29.25%; while drought stress could inhibit the synthesis of constituents of 7 kinds such as nonanedioic acid monomethyl ester, etc. Different degrees of drought stress could induce various kinds of aromatic constituents, and the number of aromatic constituents induced in fresh leaves increased with the strengthening of drought stress.
