Abstract
Seed priming is an useful technique for increasing germination and early establishment of seedlings. In this experiment, the conditions for priming of pasture seeds (tall fescue, orchardgrass, alfalfa and white clover) have been optimized to ensure an early germination and more uniform growth of seedlings. The experiment was conducted in a split plot design with three replications. The main plots consisted of four different priming duration such as 2, 4, 6 and 8 days for grass, and 1, 2, 3 and 4 days for legume. The subplots were consisted of three priming temperature such as 10, 15 and $20^{\circ}C$. Effects of priming duration and temperature were different in all four pasture seeds examined. The germination of primed grass (tall fescue and orchardgrass) was the highest on 6 days in priming duration, whereas that of legume (alfalfa and white clover) was the highest on 2 days. In priming temperature, the germination of primed orchradgrass increased as decreasing temperature, however that of legume increased as increasing temperature. These results suggest that seed priming induced earlier and higher germination for all four pastures tested. However, the degree of priming effectiveness on pasture species depending on the priming duration and its temperature.
