화아가 형성된 숙근성 자생식물 14종을 대상으로 광도를 달리하여 개화에 미치는 반응을 조사한 결과, 평균 개화율은 33.3~100%, 평균 개화소요일수는 2.7~25.3일, 평균 개화기간은 3.7~21.8일로 종에 따라 차이가 컸다. 개화율은 무늬둥굴레, 병아리난초, 복수초, 좀 비비추, 좀양지꽃, 한라구절초와 한라돌창포의 경우 광도에 관계없이 100%였다. 감자난초, 분홍노루발과 분홍할미꽃은 2,500lux에서, 금새우난초, 앵초와 황금두메냉이는 10,000lux에서 높았다. 개화소요일수의 경우, 무늬둥굴레와 한라돌창포는 2,500~5,000lux에서, 감자난초, 금새우난초, 깽깽이풀, 병아리난초, 복수초, 분홍노루발, 분홍할미꽃, 앵초, 좀비비추, 좀양지꽃, 한라구절초, 황금두메냉이는 10,000 lux에서 짧아졌다. 개화기간의 경우 병아리난초와 감자난초는 2,500lux에서, 금새우난초, 분홍할미꽃, 좀비비추, 좀양지꽃, 황금두메냉이, 한라구절초는 10,000lux에서 가장 길었으며, 특히 앵초는 3.5배나 연장되었다. 금새우난초, 깽깽이풀, 병아리난초, 복수초, 분홍할미꽃, 좀양지꽃과 한라구절초는 개화소요일수와 개화기간간에 부의 상관관계 즉 개화가 빨라지면 개화기간이 연장되었는데 비해, 한라돌창포는 정의 상관관계 즉 개화가 지연되면 개화기간이 길어졌다.

The result of this study shows that the average flowering percent was 33.3 to 100%, days to flowering was 2.7 to 25.3 days and flowering period was 3.7 to 21.8 days in 14 species of perennial Korean native plants at the stage of flower bud formation under different light intensity condition contribu...
The result of this study shows that the average flowering percent was 33.3 to 100%, days to flowering was 2.7 to 25.3 days and flowering period was 3.7 to 21.8 days in 14 species of perennial Korean native plants at the stage of flower bud formation under different light intensity condition contributing to significant differences according to species. Flowering percent was 100% regardless of light intensity in Polygonatum odoratum var. pluriflorum for. variegatum, Amitostigma gracilis, Adonis amurensis, Hosta minor, Potentilla matsumurae, Chrysanthemum zawadskii var. coreanum, and Tofieldia fauriei. It was enhanced at 2,500 lux in Oreorchis patens, Pyrola incarnata, and Pulsatilla davurica and at 10,000 lux in Calanthe discolor for. sieboldii, Primula sieboldii, and Cardamine resedifolia var. morii. Effective light intensity for shortening days to flowering was 2,500 to 5,000 lux for Polygonatum odoratum var. pluriflorum for. variegatum and Tofieldia fauriei, and 10,000 lux for Calanthe discolor for. sieboldii, Pulsatilla davurica, Hosta minor, Potentilla matsumurae, Cardamine resedifolia var. morii, and Chrysanthemum zawadskii var. coreanum. Flowering period was prolonged under 2,500 lux for Amitostigma gracilis and Oreorchis patens and 10,000 lux for Calanthe discolor for. sieboldii, Pulsatilla davurica, Hosta minor, Potentilla matsumurae, Cardamine resedifolia var. morii, and Chrysanthemum zawadskii var. coreanum, in particular, representing 3.5 fold of increased rate for Primula sieboldii. Correlation between days to flowering and flowering period was negative estimate representing prolonged flowering period led by shortened days to flowering in Calanthe discolor for. sieboldii, Jeffersonia dubia, Amitostigma gracilis, Adonis amurensis, Pulsatilla davurica, Potentilla matsumurae, and Chrysanthemum zawadskii var. coreanum. On the contrary it was positive estimate representing prolonged flowering period led by delayed days to flowering in Tofieldia fauriei. From above results, the most efficient light intensity was 10,000 lux for days to flowering promotion and flowering period prolongation in Calanthe discolor for. sieboldii, Jeffersonia dubia, Adonis amurensis, Pulsatilla davurica, Primula sieboldii, Hosta minor, Potentilla matsumurae, Chrysanthemum zawadskii var. coreanum, and Cardamine resedifolia var. morii. Meanwhile, the most effective light intensity was 2500 lux for flowering promotion and 10,000 lux for flowering period prolongation in Polygonatum odoratum var. pluriflorum for. variegatum and Tofieldia fauriei. And it was 10,000 lux for flowering promotion and 2,500 lux for flowering period prolongation in Amitostigma gracilis and Oreorchis patens.
