Seed
dormancy for Australian native species for sustainable minesite
rehabilitation
Many native species can be very difficult to germinate and establish from
seed. This project aims to understand why selected native species do not
readily germinate and how these problems can be overcome. Methods
investigated include scarification (abrasion to the seed surface), smoke
treatments, artificial ageing of the seeds, heat shock, and hormone and
enzyme treatments. In the last phase of the project, practical treatments
for nursery and field use are being developed. The expectation is that these
results will provide valuable insight into the development of practical,
cost-efficient methods to stimulate germination of difficult to establish
yet important revegetation species.
