영문 초록

This research was conducted to develop a seed propagation protocol for the use of Broussonetia kazinoki Siebold ex Siebold & Zucc, which native to East Asia. Light and temperature conditions, GA3 treatment, and low-temperature stratification were performed to evaluate the germination characteristics. The germination percentage at 4, 15/6, 20/10 and 25/15℃ was 0, 42. 5, 44. 4 and 91.7%, respectively. Thus, the optimal germination temperature of the B. kazinoki seeds was 25/15℃. Although germination was delayed by relatively low temperature conditions, GA3 treatment allowed for increased germination rates even under the low temperature conditions. Cold stratification reduced time to germination. Relatively low germination percentages at 20/10℃ and 15/6℃ indicated that the seeds had been under the state of conditional dormancy. Through this study, B. kazinoki seeds have conditional dormancy because they can be germinated through GA3 treatment even under relatively low temperature conditions and it is judged that it will support the commercial propagation practice in the future.
