농업계는 농업정책자금과 보조금 유용 문제가 발생하지 않도록 주의해야 할 것이다. 불경기에는 다른 사람을 배려하는 마음이 약해지고, 자신의 이익을 챙기는 마음이 강해진다. 쌀 직불금의 부당수령이나 면세유 불법유통과 같은 세금 유용 행위에 사람들은 더 분노하게 된다. 몇 사람이 저지른 잘못으로 농업계가 매도당하지 않도록 해야 할 것이다. 사람들은 불경기에서 빨리 벗어날 수 있다면 영혼이라도 팔려고 할지 모른다. FTA가 불경기 탈출에 도움이 된다면 마다하지 않을 것이다.

그 동안 우리나라 조경수목의 생산현황에 대한 자료는 현재 산림청, 조달청, 한국조경수협회와 발주처별로 매년조사 되고 있으나 통계조사치의 정확성과 신뢰 등이 낮았고 또한 규격별 조사가 행하여 지지 않고 수목의 수령별, 경급별로 조사되어 실용상의 활용가치가 적었다. (중략)

This paper introduces the elaboration of official documents, archival organizations, and the tradition of records in Mongolia from 1694 to 1921. Modern records management began in 1912. Back then, Mongolians had special rules to send and receive official documents, and to register the sent and received official documents. Official documents were used to deliver decrees and policies of the Khan and were used to deal with internal affairs. After their independence in 1911, the traditional documents were collected and preserved. Records managers and archivists were trained by decrees in Mongolia.

Though mulberry fruit is known to a by-product that was produced from mulberry tree after harvesting leaves for silkworm rearing, as a yield and consumption of mulberry fruit was increased, it has been fixing to a new income crop. But, a stable production of mulberry was issued on damage by the weather disaster, so it is requires that agricultural disaster insurance import. So, in this study as a basic research for a importation of agricultural disaster insurance, the cultivation of mulberry for the production of mulberry fruits, the shape of tree, the number of a bearing fruit from each cultivar, the occurrence of mulberry fruit sclerotic disease, and a yield and the market price of mulberry fruits were investigated and that results obtained were as follows; The number of mulberry tree each 10a was abundant in Buan and Jeongeup region that cultivated a suitable cultivar on low cut shape, however, a large cultivated Gochang region was little. The number of a bearing fruit per 1m on the branch was highest in the variety of Cheongilppong at Gochang. Yield of mulberry fruits each 10a was Cheongilppong at Gochang, followed by Iksuppong at Sangju. Average sale price of the mulberry fruits was high in the order of Gwasang No. 2, Suwonppong, Iksuppong, and Cheongilppong.

The fructification characteristics, fruit quality, and yield of the 'Hwangsil' jujube tree were analyzed at various stages of growth age (3-8 years old) to obtain basic data for developing high-quality jujube production technology. The average height, crown area, stem diameter near the root, stem clear length, the number of the main branches, and the distance between any two main branches were 230.8 cm (224.4~247.2 cm), 3.0 m² (2.1~3.8m²), 4.8 cm (2.4~6.2 cm), 69.1 cm (46.6~78.0 cm), 12.9 (8.6~19.6), and 8.1 cm (7.4~9.0 cm), respectively. Tree age was positively correlated with the crown area, stem diameter near the root, but stem clear length negatively correlated with the number of main branches. The average number of fruits per mother bearing shoot and tree was 20.0 (14.3~26.3) and 302.8 (257.3~373.5), respectively. There was no correlation between tree age and fructification characteristics, such as the number of fruit-bearing mother shoots per the main branch, the number of fruit-bearing shoots per fruit-bearing mother shoot, and the number of fruits per fruit-bearing shoot. Since the shape of the jujube tree is constantly managed based onthe growing area and type of greenhouse where the tree grown. The average fruit weight, fruit hardness, and soluble solid content were 24.2 g (22.4~26.8 g), 28.4 N (27.3~30.0 N), and 19.0% (17.1~19.8%), respectively, with no correlation between the tree age and fruit quality. The average yield was 7.4 kg per tree (5.7~9.1 kg), with significantly high quantities were produced in six and seven years old trees.

This study aimed at more precisely estimating the age of big old trees using dendrochronological method. Gesan-gun in Chungbuk (CBGS), Gurye-gun in Jeonnam (JNGR) and Uljin-gun in Gyeongbuk (GBUJ) were study areas and Zelkova serrata (ZS) and Pinus densiflora (PD) selected as protected trees therein were used as experimental tree species. The increment cores were extracted from 12, 8, and 6 ZSs and 10, 3, and 9 PDs in CBGS, JNGR, and GBUJ, respectively, using an increment borer (${\phi}5.2mm$). In order to clearly distinguish tree-ring boundary, the surface in the transverse section was cut for ZS using a sliding microtome and sanded for PD using a sand paper. Ring widths were measured in the resolution of 0.01 mm. Based on the measurement values, 203-year long (1813-2015) ZS local master tree-ring chronologies were successfully established and 175-year long (1841-2015) ZS local master tree-ring chronology for JNGR was also successfully established. In the case of PD, 154-, 175-, and 250-year long local master tree-ring chronologies for CBGS, JNGR, and GBUJ were successfully established, respectively. In the comparisons between local master tree-ring chronologies, they showed low t-values and Glks. According to the comparisons of the local master tree-ring chronologies with 50-year (1950~2000) average temperature and precipitation distribution maps, the annual variations of local master tree-ring chronologies seem to be determined by not temperature but precipitation. For such cross-dating therefore more local master tree-ring chronologies have to be established at the least based on the distribution map for precipitation.

The physico-chemical characteristics of core sediment, community dynamics of Salix species during the sedimentation were investigated in 1990~1997 for the purpose of inquiry to reveal the effects of terrestrialization on the environment and plant community in a natural wetland. The study site, Paksil-nup wetland was a valley blocked lake located near Hwang-River, Hapcheon-gun, Gyeongsangnam-do, Korea. The values of conductivity, organic matter, total nitrogen, exchangeable K, and exchangeable Ca were higher, and pH was lower in the upper layer of the core sediment. Soil properties such as available phosphorus, exchangeable Ca, exchangeable Na increased, and organic matter, total nitrogen, exchangeable K decreased during the sedimentation. Salix nipponica was the dominant species, and Salix glandulosa was subdominant among 10 Salix species. Sahx species were supposed to be the pioneer plants in shrub and tree layers during the succession in Paksil-nup wetland. Age class of SaliX species community from the epilittoral zone to the infralittoral zone were low, and age of Saljx species distributed from 2 years to 11 years. DBH, height, mean number of branches, number of herb species, and light intensity were increased, whereas density was decreased from a lower age to a higher age community. Salix nipponica was superior than Sahx purpurea var. japonica and other Salix species during the interspecific competition among Salix species.

Studies were carried out to compare from the viewpoint of peroxidase isoenzyme patterns by ages, locations and organs. In addition, the relationships among six cultivars peroxidase isoenzyme patterns were compared and the relationships between cultivars and their hybrids were examined. The results are summarized as follows. 1. The zymogram was not affected by the ages of 'Fuji' cultivar. 2. There was no locational difference in zymogram among Suwon, Taejon and Yesan in 'Fuji' and 'Tsugaru' cultivars. 3. Significant difference in isozyme patterns was found between stems and leaves in 'Fuji' and 'Tsugaru' cultivars. 4. There were some differences in zymogram among 'Ralls Genet', 'Fuji', 'Jonathan', 'Starking', 'Golden Delicous' and 'Tsugaru' cultivars. 5. Classification was made by the peroxidase isozyme development between cultivars and their hybrids. 1) The type showed both parent's isozyme pattern. 2) The type showed a loss of a part of parent's isozyme bands. 3) The type developed new isozymes which were not detected in parent plants.
