Dormancy mechanisms of Australian native plant species

Rehabilitation of post-mined sites in Australia depends on the effective and efficient use of native seed. Typically two-thirds of native plant species have mechanisms in the seeds that prevent germination unless the seeds are treated. Some of these mechanisms are very complex. This project, sponsored by several companies through AMIRA and ACMER, is collaborative between the University of Queensland and Kings Park and Botanic Gardens in Perth. It has the two basic objectives:
 

• Define the structural and biochemical mechanisms by which dormancy occurs in seeds of nominated Australian native species.

• Devise practical and efficient methods for breaking dormancy that can be applied to seeds broadcast on mine sites.
