(A) Pollination schedules significantly influenced floral longevity in C. heterophylla. Each bar represents the average days to corolla abscission (± s.d.). Bars with different letters indicate significant differences in floral longevity among pollination treatments by a Tukey post-hoc comparison at P < 0·05. (B) Interactive effect of soil water and pollination schedules on longevity. The x-axis refers to different soil water treatments and individual bars refer to different pollination treatments described in Table 1 and indicated in the key: early (E), middle (M), late (L) hand-pollinations, emasculated (Em) and unmanipulated (U) controls. Bars with different letters indicate statistically significant differences across pollination schedules within a soil water treatment by a Tukey post-hoc comparison at P < 0·05.
