Relationships between pollen transfer and body size of
pollinators
Pearson correlation analysis showed that there were significant positive
correlations between the body length of five pollinator species and
pollen removal, pollen deposition, and pollination efficiency (P< 0.05) (Table 2),
suggesting that the body length increased the amount of transferred
pollen. When the moth species was excluded, the intertegular distance of
four bee species was significantly and positively correlated to pollen
removal and pollen deposition (P < 0.05) (Table 2),
suggesting that the larger bees tended to remove more pollen from
anthers and deposit more pollen on stigmas. However, there was no
correlation between the intertegular distance and pollination efficiency
(Table 2).
