Most Australian native seeds have a dormancy mechanism which delays or interrupts germination until environmental conditions are favourable, or a disturbance event occurs. Dormancy occurs through physical or physiological means. Some seeds require no treatment at all, and germinate well naturally. Others require pre-treatment to replicate natural processes that break dormancy, and is usually undertaken prior to direct seeding or seedling propagation, assisting in the germination process, and increasing establishment rates.
We offer a range of in-house pre-treatment methods. Individual species respond differently to the various pre-treatments available, and must be matched to the optimum method to maximise germination rates. These include:
- Aerosol smoke – using custom-made smoke tents and cabinets;
- Scarification – by hand, or purpose built mechanical scarifier; and
- Hot water treatment regimes.
In addition to treating seeds as part of our own normal revegetation activities, we also undertake contract seed pre-treatment for various clients.
