  • Experiment was performed to investigate the effect of light intensity on growth and flowering status of Korean native Dianthus superbus var. longicalycinus, Sedum middendorifianum, Hemerocallis aurantiaca, Iris ensata var. spontanea and Aquilegia buergeriana var. oxysepola for effective landscaping. Number of floret and flower stalk per a plant were markedly increased under full sun(about 100,000lux), and decreased with decreasing light intensity in all tested plants. This result indicate that it will be cultivated in the open for promote landscaping values. However, leaf area and plant height were more increased under half sun(22,000lux) than open(100,000lux) or shade(7,700lux) in all plants except Sedum middendorifianum. Especially, Hemerocallis aurantiaca had same number of shoot and leaf size, even if planted under shade condition to show a wide adaptation to various light intensities.

  • This experiment was carried out to find out proper culture soil for the flowerpot cultivation of Sedum kamtschaticum. Peatmoss was used for the culture soil. pH of the culture soils were adjusted to 4.5, 5.0, 5.5 and 6.0 using calcium hydroxide. Young plants of Sedum kamtschaticum were planted in the pots of 10cm in diameter. The experiment was conducted by the completely randomized design with 3 replications. Growth characteristics were investigated at intervals of 30 days after planting. As the pH of culture soil is lower, growth of Sedum kamtschaticum showed longer plant height and more number of leaves and branches. pH 4.5 to 5.0 appeared to be optimum range as soil reaction of Sedum kamtschaticum cultivation.
