  • 우리나라 황칠나무의 자생지인 전남 완도지방에서 황칠나무의 재배시 삽목번식법을 체계적으로 확립 하고자 시험을 실시한 결과는 다음과 같다. 1. 삽목의 종류로는 숙지삽과 녹지삽이 가능하였으며, 숙지삽 보다는 녹지삽이 캘러스형성이 양호하고 발근율이 높은 경향이었다. 삽목시기는 숙지삽은 2월${\sim}$3월 중순경 실시하고, 녹지삽은 2월${\sim}$3월경 실시하는 것이 발근율이 높아 적당한 시기로 판단된다. 2. 황칠나무의 경삽시 삽식형태는 관삽(normalcutting)보다는 단자삽(earthen-ball cutting) 이 캘러스 형성율이 높고 발근이 양호하였다. 3. 상토는 통기성과 보수성이 양호한 사양토가 발근에 효과적이었으며, 경제성이 있을 것으로 생각되어 적당한 상토로 생각된다. 4. 식물생장조절제는 IBA(indole butyric acid)를 100ppm처리할 경우 캘러스 형성율이 높고 발근이 촉진되는 경향이었다.

  • 삽목시기가 진달래의 발근에 미치는 영향을 알아보기 위하여 시기별로 삽목하여 본 결과 5월부터 6월에 걸쳐서 비교적 높은 발근율을 얻을 수 있었는데, 6월 12일에 실시한 삽목에서 92.5%의 발근율을 나타내었다. 그러나 생식생장이 시작되는 7월 이후에는 발근율이 현저하게 낮아졌다. 즉 진달래의 삽목 최적기는 6월 중순으로 판단되었다. 관행 녹지삽목(greenwood straight cutting)과 녹 종삼목(踵揷木)(greenwood heel cutting)간에는 발근율에 있어서 별 차이를 보이지 않았다. 5월 15일에 실시한 숙지삽 결과 45%의 발근율을 보였으며, 6월 12일에 흰진달래를 삽목하였을 때에도 85%의 발근율을 나타내었다. NAA, lBA 및 Rootone 의 처리효과 실험에서 일반적으로 $200mg{\cdot}L^{-1}$의 저농도에서 12시간 동안 처리하는 것에 비하여, 고농도($2,000mg{\cdot}L^{-1}$) 에서 수초간 처리하는 것이 발근촉진효과가 좋았는데, NAA $2,000mg{\cdot}L^1$에서 15초간 침지처리하는 것이 가장 효과적이었다.

  • This experiment was carried out to establish the optimum cutting time, plant growth regulator, and bed-soil for rooting by greenwood cutting of Schisandra chinensis. Approximately 7 cm long-shoots of greenwood cuttings were transplanted by various cutting times, plant growth regulators, and bed-soils in the plastic-film house. The rooting rate of greenwood cutting was 12.5% in the April 5th, 73.5% in the May 8th, and 75.5% in the August 5th. The number and length of primary root in greenwood cutting were more in the early May than those in the early August. For mass propagation of Schisandra chinensis. using greenwood cutting, shoots were treated with plant growth regulators on May to increase rooting rate. Rooting rate was 100% with IAA $50mg/{\ell}$, 92.9% with NAA $100mg/{\ell}$, and NAA $1,000mg/{\ell}$, for 60 min. To select effective media for rooting, various medias for bed-soil were treated by single and mixture form for 100 days after cutting. Rooting rate was 91.8% in the single treatment of peat moss or decomposition of granite soil, and this result was better than those in other treatment. The treatment by 1 : 1 mixture of peat moss and horticulture bed soil was rooting with 94.0% best rooting rate.

  • Tamarix chinenis blooms twice a you and its flowers, branches and leaves make the adjustment of tree shape. Propagation methods and growth characteristics of T. chinensis were studied in order to ascertain its potential use as one of vegetation resources for coast forestation and landscaping. The study results indicated that 1 or 2 you old hard wood cuttings showed higher rooting ratio than greenwood or semi hard wood cuttings. One to one mixture between vermiculite and pearlite appeared to be the best for bed soil, and sea sand and silt(loess) mixture was the next. Sea sand and granitic soil followed after. In terms of seasonal differences, spring cuttings showed the best rooting ratio, root number, and root length. Fall cuttings followed after spring cutting, and summer cuttings showed worst results regarding rooting ratio, root number, and root length. The best rooting promotion effects of growth regulators were observed with sea sand bed soils. There was no significant difference among growth regulators in terms of rooting and shoot growth. Low concentration below 100 ppm of growth regulators was enough for rooting promotion effect. In general, the number and mean length of roots and shoots were showed the excellent records in the sites with high rooting ratio. The study result strongly showed that T. chinensis can be considered as a suitable tree for coast forestation and landscaping because of its easy cutting propagation and rapid growth on saline lands.

  • Rhododendron mucronulatum for. albiflorum, native species is a shrub that has white flowers on May to June, and rare species endangered by people's rash digging or cutting. But its physiological ecological characteristics and propagation method are not being known at all. Therefore, this study was executed to utilize this species as the planting material for landscaping by analysing its habitat environment and growth form, and also experimenting its seed and vegetative propagation, and it field culture and utilization. The results are as follows; 1. The elevation, gradient and direction of this species were 295-1,350m, 10-36$^{\circ}$, northwest respectively. It was found that the species is shade-liking plant that grows under forest cover of average 51.33%. 2. The soil pH and water content of its habitat were 5.4, 25.41% respectively. The organic matter content was 6.29% that was higher than 3.2%, the average organic matter content of forest soil in Korea. 3. Representative plant community within which this species was living was Quercus mongolica community, and its main neighboring species were Lindea obtusiloba, Fraxinus sieboldiana, Rhus trichocarpa, Rhododendron Schlippenbachii, Rododendron mucronulatum. 4. The leaf length and width of this species were 39.18mm, 12.60mm respectively. This result showed that generally its leaf size was larger than that of R. micranthum, R. yedoense var. poukhanense and R. mucronulatum var. ciliatum and smaller than that of R. mucronulatum and R. schlippenbachii. 5. The whole size of its pollen was, as 59${\times}$61$\mu\textrm{m}$, the largest of plants of Rhododendron family including R. mucronulatum and R. mucronulatum var. ciliatum. 6. The result of seed germination experiment at intervals of 5$^{\circ}C$ from 15$^{\circ}C$ to 30$^{\circ}C$ presented the highest germination rate of 94.7% at 20$^{\circ}C$ numerically, but high percent germination at all temperature levels without significant difference. And the seed of this plant proved to be sun-liking seed at requiring dormancy in germination. 7. Through seed germination experiment by treatment of growth regulators such as GA. Thiourea and Kinetin under dark condition, it was found that the effect of GA treatment on germination increase and acceleration was the highest. 8. In greenwood cutting, rooted rate by treatment of various concentration of IBA and NAA on clay and vermiculite bed was not wholly high, but 100ppm plots of both IBA and NAA of clay bed showed relatively good rooted rate. 9. As result of field culture experiment for finding out optimum growth temperature and light intensity, growth conditions such as height, number of leaves, fresh weight and chlorophyll contents were the best at night/day temperature of 20/25$^{\circ}C$ and under 1/2sun. Also, the photosynthetic rate was the highest at 25$^{\circ}C$. Accordingly, it was found that optimum temperature and light intensity for growth of this plant are 25$^{\circ}C$ (day temperature), 50% of natural light respectively.
