4.2.1.51 additional information a decrease in catechins content, 2-phenylethanol, and PDT activity is observed in the tea shoots infested by Exobasidium vexans over healthy shoots. Drought stress induced by withholding water for a period of 8 days causes initial increase in the contents of the catechins and 2-phenylethanol, and in PDT activity, but decreases with 3 day onwards with an increase in the severity of water stress, detailed overview Camellia sinensis
