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℃, day length 12/12 h) (retardation: 28/18, 32/22, 36/26, and 40/30℃, 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℃ was relatively shorter than the other treatments. This result demonstrated that when bud sprouted, the temperature above 20/10℃ 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℃ was relatively shorter than the other treatments. Thus, below 36/26℃ should be maintained for normal dormancy release and growth of variegated Solomon’s seal in summer season.
