| Research Abstract |
Black locust shows seed heteromorphism that produce both non-dormant and dormant seeds. To produce non-dormant seeds at younger stage would be advantageous, since they can expand population rapidly by immediate germination and establishment on the newly created open sites. On the other hand, most of elder trees tend to shed dormant seeds which form soil seed bank which contribute to recover following disturbance destroyed mature stands. Consequently, seed hetromorhism in Black locust attributes to its rapid expansion of this species at river basin.
