  • 제주도 한라산 낙엽수림에서 우리나라 미기록속인 난초과 영아리난초속의 영아리난초가 채집되었다. 본 종은 대만과 일본의 열대 및 아열대에 주로 분포하는 것으로 알려져 왔다. 영아리난초속은 식물체가 흔히 녹색이며 잎은 단생이고 주름이 있으며, 화아가 성장하기 전에 발달하고 낙엽이 되며, 줄기는 분지하지 않고, 화분괴는 2개이며, 대부분 점착체가 없는 점에서 난초과 Nervilieae족의 다른 속과 뚜렷하게 구분된다.

  • In vitro conservation is one of the most effective strategies for rare plant protection, especially for orchid species. To maximize the success rates of in vitro explant establishment (stage I) in conservation programs, the application of tissue culture additives such as Plant Preservative MixtureTM (PPMTM) should be emphasized. In this study, we used Dendrobium thyrsiflorum Rchb.f. (1875) seeds and seedlings as a model for the evaluation of PPMTM's phytotoxicity in the meristematic tissues of epiphytic orchids. PPMTM had no observable inhibitory effect on protocorm, shoot, or root development when it was supplemented at 0.1%. PPMTM supplementation caused adverse effects on D. thyrsiflorum explants at concentrations > 0.2%. At high concentrations, young in vitro seedlings showed damage, especially at the root tissue level. Based on this model, supplementation of 0.1-0.2% PPMTM to culture media was successfully implemented to establish in vitro cultures of other rare orchid species in our conservation program.
