Abstract
The investigation was carried out to evaluate the effects of soaking and wetting treatments on the dormancy breaking and enhancement of germination of green panic seed. The results obtained were as follows ; 1. Soaking both in running water and in water in a cup increased germination percentage in the test soon after soaking, and the seed soaked in running water germinated faster. 2. Soaking and drying treatment a month after harvest when the seed exhibited deep dormancy improved germination markedly in the tests a year or more after the treatment. In this experiment soaking treatment of 77 hours was more effective than the treatment of 3 or 24 hours. While the soaking and drying treatment 3 or 5 months after harvest when the seed exhibited shallow dormancy deteriorated germination in the tests 3 or more months after the treatment. 3. As the results of wetting treatment, enveloping ears in vinyl film for 3-7 days immediately after harvest, dormancy breaking of the seed slowed down for some time, but a year later germination percentage increased markedly and germination was nearly finished within 5 days after setting. 4. When soaking and drying treatment was done 3 months after harvest to the seed from ears enveloped in vinyl film for 7 days, germination was better than that of the seed without soaking and drying.
