수태에 심은 도자기 분화 식물의 온도 및 차광처리가 생장에 미치는 영향 Effect of Temperature and Shade on the Growth of Pottery Plants Planted in Sphagnum Moss
pp.337-344
This study aimed to evaluate the growth of Ilex cornuta Lindl. & Paxton, Cotoneaster dammeri, Ardisia pusilla ‘Variegata’, and Ilex aquifolium 'Silver Queen' when sphagnum moss was used for media, and the pottery plants were submitted to different temperatures and shade levels. After transplantation to pottery pots with Sphagnum Moss, the growth of I. aquifolium 'Silver Queen' at 25℃ of soil was the highest with 16.8 cm in plant height, 75.0 in leaf number, 256.5 cm2 in leaf area, 18.9 g in fresh weight. I. cornuta Lindl. & Paxton and A. pusilla ‘Variegata’ were in the same range but soil temperatures of 15℃, 20℃, or 30℃ had no effect and the survival rate remained 100%. On the other hand, when I. aquifolium ‘Silver Queen’ was submitted to night temperatures of 4℃, 8℃, 12℃, or 15℃, the following results were obtained: 14.1 cm in plant height, 70.0 in number of leaf, 221.1 cm2 in leaf area, and 18.9 g in fresh weight at 15℃; C. dammeri showed similar results. The survival rate at night temperature 4℃ or 8℃ was 100%, but the plant growth was sluggish. In shading 30% or 60%, the fresh weight of I. aquifolium ‘Silver Queen’, I. cornuta Lindl. & Paxton, and A. pusilla ‘Variegata’ was increased at shading 60% as the plants became taller. Non shading increased the leaf number and leaf area of plants compared with shading. In conclusion, the quality of small woody plants in pottery can be improved when the plant is grown before shipping at a soil temperature of 25°C and a greenhouse night temperature of 15°C, at 30% shading after acclimation
