Gentiana scabra Bunge var buergeri Max, can be widely used such as cut-flower, ornamental and medicinal plant among the native plants. Microscopic and Scanning electron microscopic pbservation plant were carried out to estimates the chracteristics correlated with germinability and germination process, and the results were as follows. The seeds were germinated just after harvest, and it means that there is on or little dormancy of the seeds. Matured seeds showed higher germinability than those of matured. The average longevity was about 190 days. According to the observation results of morphological changes during the germination, seed coat was expanded with water absorption immediately after seeding, and radicals were observed 2 days after seeding. Root hairs were formed behind the growing tip of the root on 4 days after seeding and cotyledon were unfolded on 6 days after seeding. In the microscopic observation of leaf tissues, it could be easily disinguished between midrib, and leaf blade, and also observed upper epidermis, palisade parenchyma and spongy parenchyma consisted as a single layer. Palisade parenchyma was consisted of a single layer of cell. Sttomata were restricted lower surface, arranged as anamocytic type, and surrounded by gurad cells. In the microscopic anatomy of wtem were consisted of cortical layer, forming a single layer of epiderms and parenclyma, and vascular bundle which was consisted of continuous cylinder of vascular tissues.
