Treatment with gibberellic acid induces more germination in a number of Pilbara grass species than does stratification. Eriachne flaccida is the most suitable perennial grass for rehabilitation trials (particularly on heavy soils). It germinates successfully without pre-treatment. Germination percentage of Chrysopogon fallax is also reasonably high without pre-treatment. For short-term plant cover, Iseilema membranaceum is most suitable as mature seed is readily collected and viable. Germination is enhanced with pre-treatment by high temperature storage and gibberellic acid.
