Ecological Implications of a Flower Size/Number Trade-Off in Tropical Forest Trees
Figure 2
Effects of calyx tube diameter (flower size, mm) on estimated flower and fruit production in 11 dipterocarp tree species.
Effects of calyx tube diameter on estimated (a) maximum per capita flower production, (b) maximum per capita flower production scaled to basal area and mean species tree height, (c) maximum per capita fruit production, (d) maximum per capita fruit production scaled to basal area and mean species tree height, (e) mean percentage of flower styles with pollen tubes and (f) mean number of pollen tubes per pollinated flower for four canopy (open symbols) and seven emergent (closed symbols) dipterocarp species growing in Sepilok Forest Reserve, Sabah. Maximum flower and fruit production were estimated from the mean of the upper quartile of values per species (n = 2 to 14 individuals per species).
