Abstract: Annual grasses are important components of vegetation, especially where perennial grasses have declined from overgrazing. Panicum laevinode is an annual grass that occurs in large numbers in grassy Eucalyptus victrix L. Johnson and K. Hill coolibah woodland in Pilbara, Western Australia. Little is known about the seed germination pattern and requirements of this grass. Our aim was to examine the effect of heat pre-treatment on seed germination of P. laevinode. Only 12% germination was observed from seeds pre-treated at 60oC for periods ranging from 1 to 8 weeks. However seed viability study showed that 61.5% and 71.5% of seeds were viable from 3 and 17 months respectively. Germination study did not reflect results of the viability test.
