The exploration of Korean spontaneous flora for introducing some interest species in Romania.
Republic of Korea enjoys similar climatic conditions as Romania, there are wide variations of temperature and precipitation. The mean temperature throughout the 4 seasons ranges from 5°C to 16°C and rainfall from 500 to 1 500 millimeters. Such an environment makes the land a diversified floral region. Lee Woo-tchul's Lineaments Florae Korea (1997) listed 190 families, 1 079 genera, 3 129 species, 8 subspecies, 627 cultivars, 1 subvariety and 306 forms of higher plants, including pteridophytes. This means that more than 4 000 kinds of vascular plants, including about 570 endemics currently grow in the country. To study the diversity of flora in Romania and Korea, a team of researchers from the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, and a team of researchers from the National Horticulture Research Institute Suwon, involved in the research project "Investigation of ornamental plant germplasm and exchange of breeding technology" initiated sharing of knowledge and collection of spontaneous flora in the both countries, enabling them to conserve the novelties in collections and to recommend for use in some breeding programs. The present paper shows some areas of South Korea that have been explored and important species from this area. Exchange of biological materials include: 30 cultivars of Gladiolus, introduction of a new floral species (Leucocoryne ixioides), and 4 species of orchids multiplied in vitro (Cymbidium virescens, cultivars Emperor's Crown, Golden Flower; Calanthe syboldii [Calanthe sieboldii]; and Lyparis).
