Abstract

To find optimum temperature on growth after dormancy release of variegated Solomon's seal for forcing and retardation culture, different temperatures (forcing: 15/5, 20/10, 25/15, and $30/20^{\circ}C$, day length 12/12 h) (retardation: 28/18, 32/22, 36/26, and $40/30^{\circ}C$, day length 12/12 h) were treated on dormancy broken rhizomes. As the temperature for forcing culture rose, days to sprouting (DTS), days to flowering (DTF) and days to flower abscission (DTFA) were significantly decreased in the former temperature treatments. However, percent sprouting and flowering, plant height and leaf numbers were not affected by temperatures. Stem length under $15/5^{\circ}C$was relatively shorter than the other treatments. This result demonstrated that when bud sprouted, the temperature above $20/10^{\circ}C$should be recommended. As the temperature for retardation culture increased, DTFA, plant height and leaf numbers were decreased in latter temperature treatments. However, DTS, DTF, percent sprouting and flowering were not affected by temperatures. Stem length under $40/30^{\circ}C$was relatively shorter than the other treatments. Thus, below $36/26^{\circ}C$ should be maintained for normal dormancy release and growth of variegated Solomon's seal in summer season.

휴면이 타파된 무늬둥굴레의 촉성재배와 억제재배시 생육 적정온도 범위를 알아보았다. 촉성재배를 염두한 낮과 밤의 온도가 15/5, 20/10, 25/15, $30/20^{\circ}C$의 처리, 억제재배를 염두한 28/18, 32/22, 36/26, $40/30^{\circ}C$ 처리에서 무늬둥굴레를 생육시켰다. 촉성재배을 위한 생육온도 실험에서 온도가 올라갈수록 맹아소요 일수, 개화소요일수, 낙화소요일수가 줄어들었다. 그러나 맹아율, 개화율, 초장, 엽수에서는 온도에 따른 유의적인 차이를 보이지 않았다. 다만 초장이 $15/5^{\circ}C$ 처리에서 상대적으로 작았다. 이 실험의 결과로 촉성재배시 $20/10^{\circ}C$ 이상의 온도를 유지하는 것이 권장할 수 있다. 억제재배를 위한 생육온도 실험에서는 재배온도가 높아질수록 낙화소요일수, 초장, 엽수에서 감소하였다. 그러나 맹아소요일수, 개화소요일수, 맹아율, 개화율에서는 온도간유의적 차이가 없었다. 초장이 $40/30^{\circ}C$ 처리에서 상대적으로 줄어드는 현상이 나타났다. 그러므로 무늬둥굴레의 억제재배시 $36/26^{\circ}C$ 이하의 온도로 재배할 것을 권할 수 있다.
