摘要：为打破省沽油种子休眠，获得可供推广利用的优质实生苗，对解除种子休眠的措施和育苗技术进行探讨，结果表明：持续低温层积处理是打破种子休眠的必要措施，以层积105～120d为宜；种子经200mg／LIAA溶液浸泡30h后低温层积处理120d，发芽率和出苗率分别为82．43％和60．35％；安徽石台县、湖北大悟县和河南桐柏县3个地点种子的播种出苗率、幼苗移栽成活率及田间保存率分别为48．08％～53．62％，91．07％～98．28％和84．26％～90．20％，1年生幼苗的苗高和地径可达74．84～86．70cm，9．96～10．34mm。
A study was conducted on the technical measures for breaking the seed dormancy of Staphylea bumalda and sapling breeding so as to raise superior seedlings for extension of the tree species. The results indicated that persistent low-temperature stratification was the essential treatment to break the seed dormancy, and the optimal stratification duration time was 105 - 120 d. The study also showed that the germination rate and seedling emergence rate was 82.43% and 60. 35% respectively after the seeds had been treated with 200 mg/L IAA for 30h and then stratified at low temperature for 120 d. The seedling emergence rate, transplanting survival rate of seedlings and the seedling preservation rate in the field were 48.08% - 53.62%, 91.07% -98.28% and 84.26% - 90. 20% respectively among the three provenances from Shitai County, Anhui Province, Dawu County, Hubei Province and Tongbai County, Henan Province. The average height and basal diameter of one-year-old seedlings reached 74. 84 - 86. 70 cm and 9.96 - 10. 34 mm respectively.
