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.
