Abstract


CHONG, Hyon Pae (Chunchun Agricultural College) Studied on the Bamboo in Korea Ⅵ. On precreation of up-land Bamboos. Kor. Jour. Bot. Ⅶ(2):9-13. 1964.
As to the up-land bamboos. I have rerorted, in my previous works, that Korea has two species in the genus or Pseudosasa, four in Pleioblastus, and other four in Sasa. In the present work, I dealt with Sasamorpha Purpurascens Nakai var. Borealis Nakai which proved the strongest vitality of all up-land bamboos yet found in various up-lands of Korea, and which might be most important from the utility view-point. This report is chiefly on its procreation. Sasamorpha Purpurascens Nakai var. Borealis Nakai can be found almost everywhere throughout the country, and its leaves and stems are much used in farms in various forms of manufacture. It is aiso welcomed as the feed for livestocks and as cover plants for aforestation, especially as the excellent means of errosion control on devastated hill sides. It is also widely accepted that it will provide, in the immediate future, abundant sources for the up-land bamboo pulp. As the first phase of my research plan on the subject, I undertook to determine the possible best way of its procreation, for which were included the experiments of inducing the growth of subterranean stems, the entire stand cutting, transplanting, reclaimed planting after burning etc. in order to observe the plant elongation, growing condition, climatical effect etc. What has been found out so far given here as follows: 1) Of the various sections of the country, Mt. Odae area gives out the most excellent Sasamorpha Purpurascens Nakai var. Borealis Nakai (the leaf weight of which is 450 gr.) and Taekwanryong area comes the next class. This species can be transplanted anywhere in the South Korea. 2) The elongation of S. p. Nakai var. Borelais begins at around the middle of May and almost completely stops by the 20th of August. 3) The best suited transplanting season is supposed to be Feb. -April, for those trantplanted during that period proved 100% of success. The next best transplanting season may be October. Rain fall does not have so much effect on transplanting as the growing season does. 4) In inducing the subterranean stems, the frowing season can be ignored. The root expansion is most amimated during the months of April-June, the most active season for water absorption. Those stems induced during the winter proves more rapid growth. 5) The entire stand cutting shows greater growth than the reclaimed planting after burning and that, the growth is most vigorous during May-July, whereas during the hottest months of Aug-Sept the growth shows only 5 ㎝. The new shoots grow slower both in the field of entire stand cutting and in the field of reclained planting after burning than in the otherwise fields.
