Lacquer (Toxicodendron vernicifluum) is expected to be used as a tree in abandoned cultivated lands. However, seedling production is challenging due to its low germinability under natural conditions. In this study, we aimed to improve the germination of lacquer by examining the conditions for breaking dormancy and germination characteristics. The seeds received 0-60 minutes of sulfuric acid scarification and were exposed to 0-100 days of cold-moist stratification prior to being germinated at different temperature and light conditions. The germination percentage improved with acid scarification for more than 15 minutes together with cold-moist stratification for more than 30 days, achieving a maximum at 90%. Light was not required for germination. There was clear temperature dependence of germination and the germination was found to be maximum at around 21 ºC. The seedling production of lacquer is expected to improve by applying appropriate germination treatments.
