The 2019 IPCC report approved that global warming of 1.5℃ will be exceeded between 2021 and 2040 if the current level of greenhouse gas emissions is maintained until the middle of this century. As global warming accelerates, climate change rapidly and frequently occurs. It also contributes to the plant extinction and loss of biodiversity. Recently, Diabelia spathulata is a critically endangered (CR) species designated by The National Arboretum of the Korea Forest Service and the habitat of D. spathulata is Cheonseongsan Mountain in Yangsan-si, Gyeongsangnam-do, where is the only native habitat site in Korea. In addition, the number of populations is very small, so it is necessary to conserve their habitats and germplasm. Various ecological researches including environmental conditions, distribution range, and vegetation structure of D. spathulata have been conducted. However, there are few reports of propagation by cuttings and micropropation of D. spathulata. Development and establishment of propagation and in vitro regeneration systems is essential for clonally and mass propagation. Thus, the purpose of this study was to find and optimize the best cutting propagation and regeneration conditions of an endangered D. spathulata.
