Descripción
The global seed industry is worth 51 trillion won, and the Korean seed industry is 800 billion won. Among them, the seed industry in the forest sector accounts for 2.5% of the total, but information on plants used for forest restoration is insufficient. Currently, the supply of seeds for plant material for forest restoration is insufficient. However, the number of important plant seeds being imported continues to grow. Therefore, a lot of research and development of the forest restoration material industry are needed to secure the seeds of native plants for forest restoration. In particular, for systematic seed production and supply, a species selection strategy and seed germination characteristics analysis are required for plant material for forest restoration. This study was carried out in accordance with the 'Notice on the Supply of Native Plants and Natural Materials for Forest Restoration (20.09.07; Korea Forest Service). We collected native plant seeds to restore damaged forests and conducted a characterization study on the collected species. As a result of seed collection, 138 points of 49 species were collected from Jeollanam-do, Gyeongsangnam-do, and Jeju. Among them, 5 gymnosperms and 133 angiosperms were included. Voucher specimens and image data information of the collected species were accumulated. As a result of seed characterization, <i>Quercus acuta</i> Thunb. and <i>Carpinus turczaninowii</i> Hance. showed a lot of abortive grains, but most showed high full seed rate. According to the results of the tetrazolium test, most species except for <i>Quercus acuta</i> Thunb, <i>Machilus</i><i> thunbergii</i> S. et Z. and <i>Carpinus turczaninowii</i> Hance had vitality. In particular, <i>Mallotus</i><i> japonicus</i> (L.f.) Müll.Arg. and <i>Raphiolepis indica</i> var. umbellate showed the highest vitality as both the full seed rate and germination rate were over 50%. This study will be useful as data for collecting native plant resources and establishing a seed supply system for restoration of damaged forests.
