Fig. 9. Specific mass transfer in the pedicel of fruits from untreated control (open circles), 2,4‐D‐treated (closed circles) and 2,4‐DP‐treated (triangles) trees. Values calculated from the rate of accumulation of dry matter in a random sample of 100 fruits from 20 trees, and the anatomical characteristics of 15 pedicels from average‐sized fruits. Vertical bars show the lowest significant difference (P ≤ 0·05) on each date.
