느티나무는 우리나라 전국에 조림 가능한 향토수종으로 앞으로 산림의 다목적 기능에 부응하기 위하여 시대적으로 많은 조림이 요구되는 수종이다. 느티나무는 심근성이며 내음성은 강하나 건조에 약하여 조림적지는 입지에 대한 요구도가 높기 때문에 계곡, 산록, 마을주변의 배수가 잘되고 통기성이 양호한 곳에 식재하여야 한다. 유시생장이 신속한 속성 활엽수로써 용도가 다양한 고급용재 조림수종이다.

This present study was conducted to investigate photosynthetic responses and chlorophyll fluorescence performances of Cornus controversa, Fraxinus rhynchophylla, Betula schmidtii, Prunus leveilleana, and Acer mono seedlings growing under four different light intensity regimes (full sun, and 65~72%, 29~40%, 7~12% of full sun). As result, Cornus controversa, Fraxinus rhynchophylla, and Betula schmidtii showed outstanding photosynthetic capacities in full sun and showed low shade tolerance. Prunus leveilleana showed good photosynthetic capacity in three treatment levels except for 7~12% of full sun and showed common shade tolerance. While, Acer mono showed good photosynthetic capacity and chlorophyll fluorescence in 29~40% of full sun. Acer mono showed the highest shade tolerance compared to the other four species.

To seek for proper regeneration methods with under-planting, Photosynthetic rate and chlorophyll contents of three broad-leaved species seedlings, Kalopanax pictum, Fraxinus rhynchophylla and Cornus controversa, were measured and compared between growing sites, below the canopy of Larix kaemferi and open land in the forest. Nursery stocks was planted in open nurs- ery in the forest in late April, 1997, and under-planting below the canopy of Larix kaemferi was conducted in late April, 1998. This experiment examined the relationships between shade-tolerance and physiological response to different light environment by tree species. To adapt the shade environment, leaves of Kalopanax pictum might be increased the more chlorophyll con- tents and photosynthetic ability than other species. From these results, shade-tolerance of the tree might be ordered Kalopanax pictum, Fraxinus rhynchophylla, and Cornus controversa.

중부이남 특히 남부해안지역에서 흔히 볼수 있는 상록성활엽관목으로 내음성이 강하여 수하에도 잘자란다. 6월에 백록색의 작은 꽃과 열매는 동양의 아름다음을 간직한 옥구슬처럼 은은한 아름다움이 피어난다. 그리고 상록의 잎은 광택이 있고 질감이 좋아서 관상수로 많은 사람들의 사랑을 받고 있는 나무이다. 또한 예로부터 우리의 집안을 지켜주는 생울타리로 많이 사용하여 우리의 전통가옥과도 잘 어울어지는 나무이다. 또한 요즘에는 다채로운 원예종으로 개발되고 있기도 하다. 이처럼 우리의 사랑을 받고 있는 꽝꽝나무에 피해를 주는 몇몇 해충 종에 대해서 생태 및 방제법을 소개하고자 한다.

This present study was conducted to investigate photosynthetic characteristics, chlorophyll fluorescence, chlorophyll contents of Betula platyphylla var. japonica, Prunus leveilleana, Magnolia sieboldii, growing under four different light intensity regimes (full sun, and 64~73%, 35~42%, 9~16% of full sun). As result, Betula platyphylla var. japonica showed outstanding photosynthetic capacity and apparent quantum yield in full sun and showed low shade tolerance. Prunus leveilleana showed good photosynthetic capacity and apparent quantum yield in 64~73% or 35~42% of full sun and showed common shade tolerance. However, Magnolia sieboldii showed good photosynthetic capacity and apparent quantum yield in 35~42% of full sun, while the lowest in full sun. Magnolia sieboldii showed the highest shade tolerance compared to the other species. As the shading level increased, the total chlorophyll contents of all species increased with significant difference.

Demand for dwarf mondo grass (DMG; Ophiopogon japonicus 'Nanus') as an ornamental garden plant is expected to grow in the future. The purpose of this study was to investigate the levels of shade tolerance and ground cover by growing DMG under a variety of shade conditions for 18 months (May 2015~October 2016). DMG plants grown in bare ground for 3 years in Jangheung-gun, Jeonnam were used for testing. In an experimental site created in Naju city in Jeonnam, the DMG was planted in planters ($70cm{\times}70cm{\times}24cm$) and covered with a shading curtain to block natural light. Shaded conditions were then arranged under different levels of shade (0%, 55% and 75%). When the plants were grown, growth (leaf size, the number of leaves, fresh weight and dry weight) and ground coverage of DMG were analyzed. According to the results, DMG growth in terms of leaf size and the number of leaves was statistically higher under zero shade (full sunlight), when compared to other shaded conditions. DMG's fresh and dry weights were significantly greater under 0% and 55% shade, compared to those under 75% shade. The degrees of shade tolerance required for normal growth of DMG were found in the range of 0~50%, meaning that more than 50% shade may decrease plant growth. There were no statistical differences in ground coverage rates of DMG under different levels of shade. When 220 tillers were planted per $1m^2$ of plot, up to 80% of the area was covered by DMG after 18 months. Since DMG requires nutrient-rich soil to grow, sufficient nitrogen fertilizers are proposed to accelerate the ground cover of DMG. As DMG remained alive over the winter in the experiments, this study also suggests that DMG can be planted in the southern temperate region.

In this study, three tree species (Populus euramericana, Kalopanax pictus and Quercus serrata) exhibiting different levels of shade tolerance were employed to investigate photosynthetic responses to the lower light condition on forest floors. Chlorophyll contents, spectral properties and photosynthetic characteristics were examined by using the tree species grown under high light intensity (PPFD $920{\mu}mol\;m^{-2}s^{-1}$) or low light intensity (PPFD $80{\mu}mol\;m^{-2}s^{-1}$). Plants grown under the low light intensity tended to have reduced leaf area, chlorophyll content per unit leaf area, light absorption and respiration in the shade intolerant tree species of P. euramericana. However, the shade tolerant species K. pictus and Q. serrata showed increased leaf area, chlorophyll content and net apparent quantum yield. Therefore, light absorption and light utilization efficiency were improved under the low light intensity. Also shade tolerant species maintained activities of photosystems and $CO_2$ fixation systems with little changes in low light intensity condition.

This experiment was conducted to investigate the effect of different levels of shading (0, 35, 55, 75, 95% to incident sunlight) on the growth of Hedera rhombea Bean and Pachysandra terminalis Sieb. et Zucc. in order to determine optimum light intensity for ground cover plants. H. rhombea showed a upright growth type under 95% shading and P. terminalis was highest under 35% shading. Number of branches was not significantly affected by shading levels. Stem diameter and length were reduced under shading from 35% to 95%. Leaf growth was vigorous under 35% and 55% shade condition. Leaves became longer with decreasing light intensity, but shorter in 95% shading than control. There was a slight trend that total chlorophyll and chlorophyll a, b contents increased with decreasing light intensity, and so did chlorophyll a/b ratio. Fresh and dry weight of both plants were higher under 35, 55, and 75% shading than control and 95% shading. Specific leaf weight tended to decrease with reduction of light intensity. Thus, optimum light intensity for growth of them may be 35 and 55% shading of incident sunlight. In addition, it is possible to grow them under even 75% shading of incident sunlight.
