ตัวอย่าง pollination

• The first external manifestation of developmental differences during seed maturation occurred about 20 d after pollination as siliques were beginning to ripen.

• The morphology of the capitula suggests they are not well adapted for pollination by other nocturnal vectors such as bats or moths.

• Since the nocturnal canopy is relatively unexplored, the phenomenon of pollination by nocturnal bees may be commoner than these limited observations suggest.

• We compared the efficiency of foraging habit of one of the major pollinators in effecting pollination.

• In this study, considerable interspecific overlap of flowering periods was found within each pollination guild.

• Unopened inflorescence buds were removed at this stage and the number of flowers which received assisted pollination recorded.

• The final treatment was unmanipulated female inflorescences exposed to both wind and insect pollination modes (open pollination).

• Seed production from experimental flowers was then contrasted with those naturally exposed to pollination and nectar removal.
