The optimum temperature for seed germination of Allium victorialis L. subsp. platyphyllum Hulten was 17 to 21℃, and the germination occurred slowly at 25℃, little at 13℃. The germination at 21℃ have only a slight influence on lighting, but the germination at 17 and 25℃ were partially inhibited by lighting. The mature seeds were in a state of endogenous dormancy at the time of seed harvesting, and were released from this dornlancy by being exposed to 25℃ or higher temperatures for 2 weeks (the effect was low in 33℃). The dormancy was also released when the seeds were treated for 2 weeks at temperature regimes of 25/17, 29/17 and 33/17℃ alterI1ating at half-day or one-day intervals. The dry storage of secds at 9℃ or lower temperatures for 6 months did not decline germinability. However, the dry storage for 9 months induced secondary dormancy in the seeds, and considerably delayed germination. The plant growth regulator, ethephon accelerated the germination of seeds. When the seeds were hawested after the time when the black seeds came to be viewed with circa 1/3 of the whole inflorescence, those seeds had the high germinability. Rinsing the seeds with running water for two days accelerated the germination.　キーワード：ギョウジャニンニク，種子発芽，種子休眠　Key words : Allium victorialis, seed germination, seed dormancy.
