Abstract

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