  • 채종원관리를 효율적으로 관리하기 위하여 시설되는 저 규격도로는 대부분 비포장상태로 이용되는 경우 많다. 이는 강우에 의한 침식붕괴로 하류의 산림식생환경 및 수질환경 오염으로 연결될 위험성이 내포되어 있어 적절한 방법으로 사전에 방지할 필요가 있다. 본 연구에서는 환경과 친화적인 재료를 최대한 이용하여 개발된 목배수로를 내구성 강화를 검토하였던바 섬유질 포의 조절과 고무질의 성능 조절에 의한 검토로 현장에의 적용이 가능하였다.

  • This report describes the damage caused by gypsy moths (Lymantria dispar) and stick bugs (Ramulus mikado) to forests and host plants in 2020. Severe tree-crown defoliation was found in central parts of Korea, especially Gangwon (1,638 ha), Gyeonggi (1,134 ha), Chungbuk (726 ha) and Seoul (476 ha). Stick bug outbreaks occurred in hilly areas, such as Mt. Bongsan, located between Seoul and Goyang.

  • Background: We measured the weight characteristics, intercellular space volume as a proportion of root volume, and quantities of the functional component in Angelica gigas Nakai, collected from four cultivation areas in Pyeongchang, including Tapdong-ri and SangjinBu-ri, and tested the results for correlations. Methods and Results: Dry weight was the highest in the Tapdong-ri group ($13.37{\pm}0.13g$) and the lowest in the SangjinBu-ri group ($11.90{\pm}0.57g$). The percentage of intercellular spaces within the roots, determined by micro-CT camera, was the highest in the Tapdong-ri group ($6.44{\pm}0.76%$) and the lowest in the SangjinBu-ri group ($9.01{\pm}2.15%$). The quantity of functional components were the highest in the Tapdong-ri group ($116.13{\pm}9.53mg/g$) and the lowest in the SangjinBu-ri group ($99.77{\pm}23.23mg/g$). Conclusions: The dry weight of A. gigas significantly correlated with the volume and percentage of intercellular space. An increase in the dry weight resulted in a negative correlation between the volume and ratio of the intercellular spaces. The volume of intercellular space correlated negatively with levels of the functional components, this was significant in the case of the nodakenin, decursin and decursinol angelate content (p < 0.016).
