The germination responses of 10 species (Acacia blakelyi, A. pulchella, Allocasuarina humilis, Beaufortia elegans, Conostylis neocymosa, Eucalyptus tetragona, Kennedia prostrata, Leptospermum spinescens, Melaleuca acerosa and Xanthorrhoea drummondii) to constant temperatures ranging from 5 to 35� C were studied. These Western Australian perennial species had optimum germination percentages between 15 and 20�C, except Eucalyptus tetragona which had an optimum at 25�C and Leptospermum spinescens which had an optimum at 10�C. Seeds were transferred from high and low temperatures to 15�C to determine whether high or low temperatures induced dormancy. Low temperatures tended not to affect subsequent germination but high temperature decreased subsequent germination for some species. Wetting and drying stimulated the germination of Acacia blakelyi, A. pulchella and Kennedia prostrata seeds.

Improve Seed Germination

Primula poissonii, an attractive wild plant growing in the subalpine/alpine region of southwest China, has low seed germination in cultivation. This study attempted to improve seed germination by testing the effect of several treatments including dry after-ripening (DAR), light, cold stratification (CS) and temperature gradient treatments. DAR increased germination at 15/5 and 25/15°C, as compared with fresh seeds. DAR seeds germinated significantly better (> 80%) at higher temperatures (20-28°C) than at lower (10°C, < 20%; 15°C, < 30%) and extreme high temperatures (30°C, < 55%; 32°C, 0%). Incubation at alternating temperature (25/15°C) did not significantly improve germination; whereas at 15/5°C germination increased significantly, compared with the corresponding constant temperature (20 and 10°C, respectively). DAR seeds had a strict light requirement at all temperatures. As DAR and CS are sufficient to break seed dormancy, the seeds of P. poissonii appear to have non-deep PD. For non-dormant cold-stratified seeds, the estimated Tb and thermal time (θ50) were 2.3°C and 74.1°Cd, respectively.
