3.2 Effects on reproductive success
Fruits in control plants produced significantly more seeds (mean = 823.6 ± 48.98 SD; N = 87 fruits) than those in robbed plants (mean = 510.7 ± 71.18 SD; N = 72; P < 0.001; Fig. 4a), with robbed plants producing 25% fewer seeds on average compared with control plants. In contrast, export of pollen grains was not significantly different between the robbed (149,167 ± 72,742 SD pollen grains, N = 50) and the control (178,329 ± 57,904 SD, N = 43) treatments (P = 0.141; Fig. 4b).
