Abstract
Daphne pseudomezereum var. koreana is native to Korea and is distributedin Kangwon-do, Jeollabuk do, and Gyeongsang-do. This economically valuable species has experienced a dramatic decrease in natural habitat due to climate change and is difficult to cultivate. In this study, we investigate a mass propagation method for D. pseudomezereum through in vitro culture and genetic resource preservation.WPM medium was better than the MS medium for shoot growth. As a result, we compared the shoot number and length of apical (W/AP) and non-apical shoots (W0/AP) with BA and GA3 treatments in WPM medium. Their shoots and length grew well in both BA 8ìM + GA38ìM-treated apical shoot and without-apical shoot. NAA did not effectively induce rooting of the in vitro plantlet.
