Abstract
The concentration of flavanols in fresh apical shoots of tea was highest during the cold season. Shoots plucked during slow growth conditions contained a higher proportion of simple catechins to catechin gallates, (−)‐epigallocatechin being most significantly affected. The predominant effect of nitrogen fertiliser was to depress the concentration of (−)‐epigallocatechin in the shoot. The significance of these findings with respect to tea quality is discussed.Keywords
