이명종,한상섭,김정제,Yi, Myong Jong,Han, Sang Sup,Kim, Jeong Je 한국산림과학회 1985 한국산림과학회지 Vol.69 No.1

Forest soils mixed with organic matters (green needle, flesh needle litter and needle litter in F layer of Pinus koraiensis, and green leaf of Quercus dentata and Q. variabilis) were incubated under a constant $30^{\circ}C({\pm}1)$ for 53 days to measure the changes of inorganic nitrogen and $CO_2$ evolution rate. The results obtained were summarized as follows; 1) In the early incubation period the amounts of total inorganic nitrogen in soils by mixture of organic matters decreased rapidly because of immobilization by microbial uptake, and thereafter their amounts increased with further incubation. 2) The rate of immobilization of organic nitrogen in mixed organic matters was the highest in green needle among green needle, flesh needle litter and needle litter in F layer of P. koraiensis, but lower than that of green leaf of Q. variabilis and Q. dentata. 3) The rates of $CO_2$ evolution from soils mixed with organic matters increased sharply in the early time, and then decreased slowly with increasing time. The order of the $CO_2$ evolution rate was green leaf of Q. variabilis > green leaf of Q. dentata > green needle of P. koraiensis > flesh needle litter of P. koraiensis > needle litter of P. koraiensis in F layer from the largest to the least. 4) Nitrate nitrogen concentrations showed a tendency to increase throughout incubation time, so that their concentrations after 53 days were higher than that of ammonium nitrogen. 잣나무의 녹엽(綠葉), 낙엽(落葉), F층(層)의 엽(葉)과 떡갈 및 굴참나무의 녹엽(綠葉)을 각각 토양(土壤)에 혼합(混合)하여 53일간 $30^{\circ}C({\pm}1)$로 항온배양(恒?培養)하는 동안 토양중(土壤中)의 무기태(無機態) 질소(窒素) 및 $CO_2$ 방출속도(放出速度)의 변화(變化)를 측정(測定)하여 다음의 결과(結果)를 얻었다. 1) 배양초기(培養初期)에는 무기태(無機態) 질소(窒素)의 유기화(有機化)로 무기태(無機態) 질소량(窒素量)의 감소(減少)가 강(?)하게 일어났고, 시간(時間)의 경과(經過)에 따라 점차 증가(增加) 하였다. 2) 혼합(混合)한 엽중(葉中)의 유기태(有機態) 질소(窒素)의 유기화속도(有機化速度)는 잣나무의 엽중(葉中) 녹엽(綠葉)에서 가장 컸으나, 굴참 및 떡갈나무의 녹엽(綠葉)보다는 작았다. 3) $CO_2$ 방출속도(放出速度)의 크기는 굴참나무녹엽(綠葉), 떡갈나무녹엽(綠葉), 잣나무녹엽(綠葉), 잣나무 낙엽(落葉), F층(層)의 잣나무엽(葉)을 혼합(混合)한 토양(土壤)의 순(順)이었고, 시간의 경과(經過)에 따라 점차 감소했다. 4) 질산태(窒酸態) 질소량(窒素量)은 점차 증가(增加)하여 배양(培養) 53일 후에, 암모니아태(態應) 질소량(窒素量)을 상회(上?)하였다.

이 연구(硏究)는 우리 나라 주요(主要) 낙엽(落葉) 관엽수(關葉樹) 21종(種)에 대하여 수목(樹木)의 줄기, 가지, 분기부분(分技部分)과 정단부(頂端部) 1년생(年生) 주간(主幹)과 측지(側枝) 등의 상대수분통도성(相對水分通導性)을 측정(測定)하여 수분통도성(水分通導性)의 부위별(部位別) 특성(特性)을 비교(比較)하였다. 1. 관엽수(關葉樹) 21종(種)의 상대수분통도성(相對水分通導性)은 $3.18{\times}10^{-15}{\sim}1.23{\times}10^{-10}m^2$의 폭넓은 범위 내에 분포하였고, 수종별(樹種別), 수체(樹體)의 부위별(部位別)로 다르게 나타났다. 2. 산공재(散孔材) 8수종(樹種)의 부위별(部位別) 평균(平均) 상대수분통도성(相對水分通導性)은 줄기가 $3.49{\times}10^{-13}{\sim}6.35{\times}10^{-11}m^2$, 가지가 $4.89{\times}10^{-13}{\sim}2.99{\times}10^{-11}m^2$, 분기부분(分技部分)이 $1.33{\times}10^{-13}{\sim}9.42{\times}10^{-12}m^2$였고, 환공재(環孔材) 13수종(樹種)은 줄기가 $7.14{\times}10^{-13}{\sim}4.76{\times}10^{-11}m^2$, 가지가 $2.93{\times}10^{-13}{\sim}3.91{\times}10^{-11}m^2$, 분기부분(分技部分)이 $1.14{\times}10^{-13}{\sim}9.20{\times}10^{-12}m^2$의 범위를 나타냈다. 3. 줄기의 직경별(直徑別) 상대수분통도성(相對水分通導性)에 있어서, 산공재(散孔材) 8수종(樹種)은 줄기의 직경(直徑) 크기와 상대수분통도성(相對水分通導性)과의 상관관계(相關關係)가 없는 것으로 나타났으며 다릅나무와 들메나무를 제외한 환공재(環孔材) 11수종(樹種)은 모두 줄기의 직경(直徑)이 작아질수록 상대수분통도성(相對水分通導性)이 커지는 경향이 뚜렷하였다. 4. 관엽수(關葉樹) 5종(種)에 있어서 정단부(頂端部) 1년생(年生) 주간(主幹) 및 측지(側枝)의 상대수분통도성(相對水分通導性)은 주간(主幹)이 $4.87{\times}10^{-13}{\sim}8.41{\times}10^{-11}m^2$이고, 측지(側枝)가 $7.93{\times}10^{-14}{\sim}2.01{\times}10^{-11}m^2$의 범위를 보였으며, 정단주간(頂端主幹)(leaders)이 정단측지(頂端側枝)(adjacent laterals)보다 1.5~8배 정도로 크게 나타나, 수목(樹木)의 정단주간(頂端主幹)은 정아우세(頂芽優勢)와 같은 수력(水力) 적(的) 우세(優勢)(hydraulic dominance)를 보였다. This study was carried out to compare the characteristics of relative conductivity(RC) in the twenty-one deciduous broad-leaved species. The results obtained were summarized as follows : 1. The RC ranged from $3.18{\times}10^{-15}$ to $1.23{\times}10^{-10}m^2$ in deciduous broad-leaved species, and appeared different values in various portions of a tree and species. 2. In eight diffuse-porous species, the ranges of average RC were $3.49{\times}10^{-13}$ to $6.35{\times}10^{-11}m^2$ in stems. $4.89{\times}10^{-13}$ to $2.99{\times}10^{-11}m^2$ in branches, and $1.33{\times}10^{-13}$ to $9.42{\times}10^{-12}m^2$ in junction part between stem and branch. In thirteen ring-porous species, the RCs were $7.14{\times}10^{-13}$ to $4.76{\times}10^{-11}m^2$ in stems, $2.93{\times}10^{-13}$ to $3.91{\times}10^{-11}m^2$ in branches, and $1.14{\times}10^{-13}$ to $9.20{\times}10^{-12}m^2$ in junction part. 3. The RC and diameter of stem have no interrelation in eight diffuse-porous species. The RC of stem increased with decreasing diameter of stem in eleven ring-porous species except Fraxinus mandshurica and Maackia amurensis. 4. In five deciduous broad-leaved species, the RC of 1-year-old shoots(the leader and adjacent laterals ) ranged from $4.87{\times}10^{-13}$ to $8.41{\times}10^{-11}m^2$ in the leaders, and $7.93{\times}10^{-14}$ to $2.01{\times}10^{-11}m^2$ in the adjacent laterals. The RCs were much greater in the leaders than in the adjacent laterals because of the hydraulic dominance of the leader shoot.

This study was performed to compare the characteristics of hydraulic conductivity such as relative conductivity(RC), leaf specific conductivity(LSC), Huber value(HV), specific conductivity(SC), and diameter of vessels(㎛) and number of vessels(No./㎟) in branch junctions of the twenty-one deciduous broad-leaved species. The hydraulic conductivities of branch junctions decreased with increasing junction angle between stem and branch, and with decreasing diameter of branch. The RC and LSC of branch junctions related to branching types( ㅏ , Y, Ψ type) were much lower in ㅏ and Ψ types than in Y type. The diameter and number of vessels remarkably reduced in branch junctions as compared with the stem and branch.

이 연구는 우리나라 주요 산채 수종인 두릅나무에 대하여 기건 보관한 종자와 냉장 보관(4℃)한 종자의 발아율 특성을 여러 광 조건(상대조도 0%, 30%, 50%, 70%, 100%)하에서 비교하였다. 조사 결과 모든 처리구에서 발아율이 70% 이상으로 나타났으며, 상대조도 0%에서 기건보관한 종자가 88%, 냉장보관한 종자가 82%로 가장 높은 발아율을 나타냈다. 그러나 발아된 종자 중 유근의 생존율은 각각 16%와 21%로 낮은 반면, 상대조도 100%의 처리구에서는 기건보관종자가 90%, 냉장보관한 종자가 99%로 높은 생존율을 보였다. This study was carried out in various light treatments(relative light intensity 0%, 30%, 50% , 70% and 100%) to compare the characteristics of germination of Aralia elata seeds that were kept under room air temperature and refrigerator storage (4℃) . The germination percentage was equal to or more than 70% in all light treatments. The maximum germination percentage of seeds stored in room air temperature and refrigerator were 88% and 82% at the dark condition, respectively. The survival rates of radicle of the germinated seeds were 16% and 21% at the dark condition but were 90% and 99% at the 100% light condition.
