We explored the temporal effects of fruit consumption on the subsequent seed germination
pattern of a fleshy-fruited tree, the Chinese hackberry (Celtis sinensis). Via nursery-based
sowing experiments, we investigated (1) how pulp removal affected seed germination
patterns at the different stages of fruit maturation, and (2) how the timing of seed dispersal
(August, October, and December) affected the germination patterns of seeds from ripe fruits
after the removal of pulp. We found that the removal of pulp from around the seeds of ripe …

Abstract
We explored the temporal effects of fruit consumption on the subsequent seed germination pattern of a fleshy-fruited tree, the Chinese hackberry (Celtis sinensis). Via nursery-based sowing experiments, we investigated (1) how pulp removal affected seed germination patterns at the different stages of fruit maturation, and (2) how the timing of seed dispersal (August, October, and December) affected the germination patterns of seeds from ripe fruits after the removal of pulp. We found that the removal of pulp from around the seeds of ripe fruit had no effect on the percentage and timing of germination. In contrast, the removal of pulp from seeds of unripe fruits largely reduced the germination percentage. The time of sowing did not affect the germination percentage, whereas the timing of germination was delayed for seeds that were sown later or under shaded environments.
