Fig. 2. Concentration of condensed tannin (CT) in leaves, flowers, and stems of ARS-2620, ARS-1221, and ARS-1207 grown in the field. Values are means of CT concentration combined over 2 yr. For each species, bars having the same letter are not significantly different at P = 0.05. Line bars represent standard error among species within a plant part. CE, catechin equivalent.
