This study was conducted to elucidate the mid-growth of Norway spruce at the age of 27 and select the superior provenances in Korea. Growth performance of twenty-four provenances from Germany and Rumania were investigated in four plantations. Significant differences were found in growth (height, DBH, volume) with plantations. Maximum growth were detected on plantation Chuncheon which located in most northern area, and minimum growth were detected on plantation Wanju located in most southern area. The rank of height in provenances has fluctuated, but superior/inferior groups have been almost fixed. 840-23, 840-10, 840-19 in Germany, G1-64-57, G1-64-54 in Rumania proved excellent provenances. Height in early stage positively correlated with that in late stage. The growth was positively correlated with latitude and altitude of plantations, but negatively correlated with temperature.

We investigated antioxidant capacity in leaves of 14 coniferous trees under field conditions. We focused on understanding the species characteristics on antioxidant systems and screening the coniferous tree species with the best antioxidant systems using their characteristics. The antioxidant capacity of 14 coniferous trees was divided into three groups. First group was Thuja orientalis and Chamaecyparis obtusa and those species had the highest content of ${\beta}$-carotene and xanthophyll. Second group, C. obtusa and Juniperus chinensis, used antioxidant enzymes to mitigate stress. C. obtusa represented high activity at superoxide dismutase (SOD), glutathione reductase (GR), and peroxidase (POD), and J. chinensis exhibited high activity at SOD, POD, catalase (CAT). Third group employed antioxidant such as ascorbic acid and ${\alpha}$-tocopherol. The antioxidant content of T. orientalis was the highest while that of Pinus parviflora and C. obtusa were the lowest. Few species belonged in three groups simultaneously, and most species belonged in at least one or two groups. In summary, we proposed that C. obtusa and T. orientalis had the highest antioxidant capacity while P. parviflora and P. desiflora for. multicalus had the lowest antioxidant capacity.

As Dr. Ogawa visited to Korea for joint research on Tricholoma matsutake, authors travelled 15 main producing districts of Tricholoma matsutake and had field survey on sample areas in these districts from September 23 to October 3 1981. The object of this investigation were to understand the actual conditions of pine forest and growing Tricholoma matsutake in Korea so as to find out relevant treatment of pine forest where the Tricholoma matsutake were growing. As a results, present environmental conditions such as weather, topography, soils, pine forest, vegetations, pine mushrooms(Tricholoma matsutake), other fungi and the relationship between Tricholoma matsutake and the diseases of pine forest were investigated. Model figures of topography and forest type on surveyed area have been drawn up. Some countermeasures to improve pine forest conditions in the aspect of producing Tricholoma matsutake were suggested through the prediction on the transition of pine forest.

This study was conducted to estimate carbon stock and uptake for Larix kaempferi Lamb., the single species, which is the most widely distributed one following Pinus densiflora, using data from 6th national forest inventory and forest type map of 1:5,000. Overall distribution area of Larix kaempferi in South Korea was shown as 272,800ha, in detail, Gangwon-do was the most widely distributed region with 39.6% (108,141 ha) of the whole forest area, and Gyeongsangbuk-do was 18.6%(50,839 ha), Chungcheongbuk-do was 15.1%(41,205ha) in order. As the results of analysis in carbon stock and uptake for each province, the values were high with Gyeonggi-do 109.0 tC/ha, $10.3tCO_2/ha/yr$, Gangwon-do 349.1 tC/ha, $9.7tCO_2/ha/yr$ in order, and Jeollabuk-do was the lowest with 78.3 tC/ha, $7.6tCO_2/ha/yr$. Also, the results of estimation in total carbon stocks and uptakes by year (1989~2015) were turned out that total carbon stocks and uptakes were 24,891 thousand tC, $2,428thousand\;tCO_2$ in 2015, increasing about 4.8 times and 3.8 times each compared with 5,238 thousand C/ha, $640thousand\;CO_2$ in 1989. Although forest area was decreased 26.6% with 371,884 ha in 1989 to 272,800 ha in 2015, carbon stocks and uptakes were increased in 2015 in that forest stock was increased 126% compared to 1989.

Total forest land in Bangladesh is about 2.5 million hectare which is 17% of total land area. Bangladeshi forest is mainly classified into three categories- 1) Hill forest 2) Sal forest and 3) Mangroves. This forest land area is decreasing day by day. But in past decayed due to some policies, the total forest land area is increasing slowly. By this planning both government and the local people in the community are being benefited. This paper mainly discussed about the past, present and future trend of forest condition, forest land uses, sustainable forest planning and forest management.

최근 기후변화로 인해 산불 발생이 빈번해지고 있으며, 산불의 크기도 대형화가 되고 있다. 우리나라 산불은 매년 100 ha 이상 산불피해가 지속적으로 발생하고 있다. 최근 5년간 강원도에서 발생한 대형산불의 90%는 동해안 지역을 중심으로 집중된 것으로 나타났다. 동해안 지역은 건조한 대기, 양간지풍 등 산불에 취약한 기후와 침엽수림의 산림 조건을 지니고 있다. 이와 관련하여 산불 발생 위험성 예측, 산불 위험도 산정 등 다양한 산불 분석과 관련된 연구들이 추진되고 있다. 기상 및 산림 관련 인자를 고려하여 산림지역에 대한 위험 분석에 관련된 연구는 많이 추진되고 있으나, 산림 인접 지역을 대상으로 위험도 분석을 수행한 연구는 아직 부족한 실정이다. 산림 인접 지역에 대한 관리는 인명과 재산 보호를 위해 중요한 일이다. 산림 인접한 주택 및 시설물들은 산불에 의해 큰 위협을 받게 된다. 이에 본 연구에서는 국가지점번호를 활용하여 산림 인근 지역에서 영향을 받는 인자들을 활용하여 격자기반 산불 관련 재난위험지도를 작성하고 강릉 산불 사례 기반으로 산림 지역과 산림 인접 지역을 대상으로 위험등급 차이를 비교하였다.

A optimal procedure for plant production via repetitive secondary somatic embryogenesis in Tilia amurensis is described. Somatic embryos were induced directly from the culture of zygotic embryos on medium with 1.0 mg/l 2,4.-D. Repetitive secondary somatic embryos formed on the surface of the cotyledons and hypocotyls except for the radicles when explants of somatic embryos were cultured on medium with 4.0 mg/l 2,4-D. The highest frequency of secondary embryo-genesis was obtained in the cotyledons (90%) and hypocotyls(83.33%) on MS medium with 1.0 mg/L 2,4-D. The average number of secondary embryos per explant was 25.74 in cotyledon and 24.92 in hypocotyl. When the cotyledon and hypocotyl segments from somatic embryos at different developmental stages were cultured on MS medium with 1.0 mg/L 2,4-D, the highest frequency of secondary embryogenesis was obtained from late cotyledonary secondary embryos. Somatic embryos were transferred to MS basal medium and then they germinated within 2 to 4 weeks of culture. Germinated somatic embryos grew normally into plantlets on WPM medium, producing new shoots. The converted plantlets were acclimatized on artificial soil mixture. These results indicate that the repetitive secondary somatic embryogenesis in T amurensis can offer the possibility to use in vitro culture system for the micropropagation.

Korea is a small country with extremely high population density. Industrialization of the nation resulted GNP per capita of over 2,000$ in 1986 with an inevitable by-product, high level of pollution in many areas. Forest land is now acknowledged as not only a wood production site but also an origin of much more important intangible values, water and clean air, soil conservation, and recreational and scenic values. Mostly devastated forest land from Korean War has been recovered under the strong afforestation drive from the government. The first Forest Development Plan was mostly reforestation phase and the second Forest Development Plan is foundation establishment phase. The third and later Plans are to enlarge economical forest and to maintain sustatined yield phase. Forestry administration as well as forest research certainly played a great role in successful accomplishment of two Forest Development Plans. For effective planning and accomplishment of the third Forest Development Plan close cooperation among policy makers, forest managers and research workers are mostly required.
