After 60 days of layering,the germination rates of Black-fruit Berberis seeds without seed coat of Huocheng population, Xinyuan population and Tekesi population were 85.00%, 83.33%, and 86.67% respectively after treated with GA3 solution of 200 mg·L-1 for 2 hours;When the Red-fruit Berberis seeds were layered for 15 days,the germination rates of Red-fruit Berberis seeds without seed coat of Tekesi population were 86.67% after treated with GA3 solution of 200 mg·L-1 for 2 hours.The results will provide technical support and scientific basis for the introduction and breeding of wild Berberis. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2018.06.013
