主要造林樹種의 凍害의 原人과 그의 Mechanism에 關한 硏究
KIM CHUNG SUK(金鼎錫),SUK KOO LEE(李錫求),SANG BUNG LEE(李相鵬),CHI MOON KIM(金智文) 한국육종학회 1979 한국육종학회지 Vol.11 No.2
The stem temperature, cold damage, frost damage of tissues and seasonal variation of sugars in cortex were measured on Populus alba × glandulosa, Populus × euramericana, Alnus inokumai, Pinus rigida ×taeda and Cryptomeria japonica, The results abtained are as follows. 1. In Populus alba × glandulosa, Populus × euramcricana and Alnus inokumai, the lowest minimum temperature and the highest maximum temperature occurred in cortex of 20cm above soil surface. 2. Super cooling in cortex of Populus alba × glandulosa, Populus × euramericana and Alnus inokumai was broken at 0~-2℃, at -2℃, and at -1~-2℃, respectively. 3. The minimum temperature in cortex of Populus alba × glandulosa and Populus × euramericana occurred early in the morning and its maximum temperature occurred early in the afternoon. This was not related to either season or direction. 4. The stem frost damage of Populus alba × glandulosa occurred mostly in the lower part of stems and to the south. Its damage rate shown below 30cm of stem height amounted to 42 percent. 5. Alnus inokumai and Pinus rigida × taeda showed weak frost hardiness in stems while Populus alba × glandulosa and Populus × euramericana showed strong frost hardiness. 6. All trees used in this study showed greater frost hardiness in stems than that in buds. 7. The stem cold-damage of Populus alba × glandulosa and Populus × euramericana increased with increasing wind velocity and with increasing length of treatment time at the same low temperature. 8. The amount of total or reduced sugars in cortex increased with decreasing temperature.

Mt. Kyeryong(828 meters in height) is located at 36°18'∼36°23' N.L. and 127°10'∼127°17' E.L., and also occupies three districts: Gongju-Gun, Nonsan-Gun, Daedeok-Gun. Authors surveyed the flora of the areas ten times from May to October, 1979. Variability of floras is rather high and dominant species are such as Pinus densiflora, Quercus mongolica, Quercus serrata, Quercus variabilis, Lindera erythrocarpa, Carpinus cordata, Acer pseudo-sieboldianum var. koreanum, Strax japonica, Sapium, japonicum, Euonymus oxyphyllus, Sorbus alnifolia, Stephanandra incisa, Weigela subsessilis, Rhododendron mucronulatum, Lespedeza bicolor, Sasa borealis, Celastrus orbiculatus, Arundinella, hirta, Miscanthus sinensis var, purpurascans, and so on. There are 105 families, 355 genera, 679 species. According to the use of floras, they can be classified as follows; 69 familia and 287 species for edible source, 83 familia and 227 species of medicinal, 60 familia and 253 species for forage, 44 familia and 132 species for ornamental and 12 familia and 39 species for timber source.
