채종원(採種園) 관리를 위해 개발된 여러 수종의 다양한 수형 조절 방법의 검토 및 이미 수형 조절 작업을 받은 16년생 접목 잣나무의 성장 조사와 I영급~III영급 조림지 임목의 성장 조사를 통하여 잣나무 인공림에서 잣과 목재를 생산할 수 있는 수형과 그 조절 방법을 제시하였다. 제 1형은 I~II영급에 잣 생산만을 위해 적용할 수 있는 방법으로 지상 1m 정도의 힘센 생지(生枝)를 포함하여 1m 정도 간격으로 4~5마디까지 남기고 단간(斷幹)하되 각 마디에 3~4개의 일차지(一次枝)를 윤생(輪生)으로 배치하는 변칙주간형(變則主幹型)이고, 제 2형은 잣과 목재 생산을 함께 도모하는 II영급~III영급에 적용이 가능한 방법으로 힘센 첫 생지 (지표에서 4m~8m)의 아래 부분은 무절(無節) 주간(主幹)으로 성장시키고 그 위는 1m 정도 간격으로 최고 4~5마디까지 남기고 단간하되 각 마디에 3~4개의 일차지를 윤생으로 배치하는 변칙주간형이며, 제 3형은 목재 생산만을 위해 지하고(枝下高)가 9m를 넘는 잣나무를 강도(强度)의 가지치기로 주간형(主幹型)을 이루게 하여 곧고 빠른 주간의 성장을 도모하는 방법이다. To improve nut production and timber quality in a plantation, crown shape controls were suggested for Korean white pines (Pinus koraiensis) under age class III through the analyses of the crown shape controls for seed orchard trees in several species, of crown status of controlled and uncontrolled trees in a Korean white pine seed orchard, and of growth characteristics of plantation trees under age class III. For nut production from the small trees less than 8 m, modified leader type can be applied by cutting the central leader and all branches below 1 m and keeping 4~5 nodes with 3~4 whorled branches a node locating 1 m apart. Trees with a 4~8 m long trunk below the first living branch are shaped into trees for nut and timber production, which have a 4~8 m long knotless stem and a modified leader type crown with 4~5 nodes with 3~4 whorled branches a node at a distance of 1 m. Trees, showing the first living branch at or above 9 m from the surface, are pruned severely for timber production and result in a central leader type containing two fifths of the initial crown. It is advisable to remove the leader and the branches when collecting cones or after/during October to take advantage of easy labor and little resin while cutting. After stem cut, branches showing apical dominance are to be cut to control height when necessary. The removal of the uppermost node may be needed to control the crown shape several years after the initial stem-cut.

목본식물(木本植物)의 재유령화(再幼齡化)

Without scientific understanding of the phase change and the rejuvenation in woody perennials, many tree breeders have successfully rejuvenated and multiplied mature trees of some tree species, i.e., Eucalyptus, Pseudotsuga menziesii Sequoia sempervirens, Pinus radiata, Pinus pinaster, Quercus virginiana, Hedera helix, Juglans, apples, grapes, and so on. Practical techniques discussed to rejuvenate the old trees include grafting to younger stock, growth regulator treatment, pruning, repeated cutting, and in vitro culture. However, a combination of skills mentioned is recommended for rejuvenation of the mature propagation material. It is strongly required to develop a morphological and/or biochemical indicator system to judge the juvenility.

For nut production from the small trees less than 8 m, modified leader type can be applied by cutting the central leader and all branches below 1 m and keeping 4∼5 nodes with 3∼4 whorled branches a node locating 1 m apart.

The embryos of Pinus taeda, P. rigida, and P. taeda × rigida were cultured for adventitious shoot regeneration in vitro. Culture media were modified from Gresshoff and Doy (MGD), Murashige and Skoog (MMS), Lloyd and McCown (MLM), and Schenk and Hildebrandt (MSH). NAA was added to initiation media at a concentration of 0.1 or 0.01 ㎎/ℓ. BAP was used at the concentrations of 0.1. 0.5, 1, 2, or 5㎎/ℓ. Each explant was induced for 3-4 weeks on solid medium. All explants were cultured up to 16 weeks. Illumination was about 1506±540 lux at the level of the tissues in the growth room with a temperature of 25±2℃. A 16-hour photoperiod per 24 hours was used. Half-strength medium was used for all the subcultures. For shoot production by loblolly pine, MMS, MLM, or MSH is preferred with 5 ㎎/ℓ BAP with either 0.1 or 0.01 ㎎/ℓ NAA. For shoot production by pitch pine, MMS, MLM, or MSH is recommended with 2 or 5 ㎎/ℓ BAP with 0.1 ㎎/ℓ NAA. For shoot production by the hybrid pine, MMS or MLM is more effective with 1, 2 or 5 ㎎/ℓ BAP with 0.1 ㎎/ℓ NAA. There were no differences recognized among the species tried in the patterns of bud formation and shoot development. Different composition of media, in major and minor salts or possibly in vitamins, should be tested for the two developmental stages of adventitious shoots ; the induction of shoot buds and the elongation of them into shoots.

제벌(除伐) 및 그 간단년수(間斷年數)가 잣나무림(林)의 성장(成長)에 미치는 영향(影響)을 조사(調査)하기 위해 1975년(年)에 설정(設定)한 시험림(試驗林)에 있어 각형질(各形質)의 성장(成長)을 처리별(處理別)로 비교(比較)한 결과(結果) 다음과 같은 결과(結果)를 얻었다. 1. 총재적량(總材積量)에 있어서는 설정시(設定時)부터 2위(位)이던 무처리구(無處理區)가 5년후(年後)인 1980년(年)부터 가장 많은 재적(材積)을 보여 1982년(年) 현재(現在) $83.27m^2/ha$를 보이고 있다. 2. 수고(樹高), 흉고직경(胸高直徑), 단목재적(單木材積)에 있어 설정(設定) 당시(當時)의 그 값과 비교(比較)한 성장율(成長率)에 있어서는 3년(年)마다 제벌구(除伐區)가 가장 높은 값을 나타내고 있다. Through 7-year experiment in Korean pine stand since 1975, the followings are obtained as the results of investigation in several characters: 1. In total volume, the highest value after 1980 was shown in the control plot, which was the second one for 4 years, 1975 to 1979. 2. In the increment ratios of height, diameter at breast height(D. B. H.), and individual volume, the plot with the intermittent period of 3 years showed the higher values than any other plot.

잣송이의 채취(採取)를 기계화(機械化)하기 위한 기초연구(基礎硏究) (I)

잣송이 수확기계의 개발을 위한 기초자료를 얻기 위하여 강원대학교 임과대학 부속연습림에서 7영급 및 4영급의 착과한 잣나무의 정단부위 성장특성과 착과특성을 1992년 8월 말부터 9월 중순까지 조사하였다. 1. 당년 성장한 가지의 길이는 4영급에서 주지는 27~56cm이고 측지는 18~47cm로 7영급보다 훨씬 왕성하였다. 2. 측지의 분지각은 $24{\sim}89^{\circ}$이었고, 2년 성장한 주지의 직경은 10~30mm로서 두 특징에 있어 영급간 유의적인 차이가 없었으나, 1년생 주지의 직청은 4영급에서 9~18mm로서 7영급보다 생장량이 더 높았다. 3. 착과수는 평균 5개, 구과 생중량은 평균 272g으로 영급간 유의적인 차가 없었다. 4. 2년 자란 주지의 착과위치는 그 마디 아랫 쪽으로부터 7영급에서는 9.7~33.0cm, 4영급에서는 18.0~51.0cm의 범위인 곳으로 평균위치는 각 마디의 1/2과 4/5되는 위치였다. 5. 착과한 나무에 있어서 구과, 1년생지 및 2년생지를 합한 총생중량의 범위는 1.0~7.4kg이었다. In the fall of 1992, growth characteristics and cone-bearing behaviour of crown top shoots were investigated on Pin us koraiensis trees, belonging to age class VII and IV, in the School Forests, College of Forestry, Kangwon National University to obtain basic information for the design of Korean pine cone harvesting machine. The results were summarized as follows. 1. The length of terminal main shoots and lateral shoots of the trees in age class IV was 27~56cm and 18~47cm, respectively, both of which were significantly higher than those of the trees in age class VII. 2. There was no significant difference between two age classes in the branching angle ($24{\sim}89^{\circ}$) of lateral shoots and in the diameter (10~30mm) of two-year-old main shoots. However, one-year-old terminal main shoots of age class IV showed the higher diameter (9~18mm) than those of age class VII. 3. Mean cone number per tree was 5, and mean fresh weight of cone was 272g. No significant difference was found in these traits between both age classes. 4. Cones, on an average, hung on the two-year-old main shoots 15cm above the basal ends in age class VII and 33cm above in age class IV. Both lengths are equivalent to one half and four fifths of the shoots, respectively. 5. The fresh weight range of crown-top shoots containing cones was 1.0~7.4kg.
