The effect of ethylene treatment on the germination of tweezers-harvested seeds was examined in two strawberry cultivars, 'Sachinoka' and 'Asuka- ruby'. In both cultivars, seeds treated with 100, 200, 500 and 1,000 ppm ethephon solution exhibited significantly higher germination rates than those of seeds treated with 0 ppm solution. However, almost all seeds treated with ethephon solution exhibited abnormal root growth. In 'Asukaruby', the germination rates of tweezers- harvested seeds treated with 1,000 ppm ethylene gas for 24 and 48 hours were significantly higher than those of control seeds. From these results, it can be considered that short- term incubation with ethylene gas is effective for increment of the seed germination rate, while the germination of tweezers- harvested strawberry seeds without any treatment remained poor.
