Abstract
|
|
|
|
In order to turn Convallaria keiskei Miq., grown natively in Korea, into floricultural plants a forcing method was developed. Low temperature treatment and growth forcing temperatures required for natural dormancy breaking time were examined. The best low temperature treatment were 0-5℃ for more than 90 days. The longer the low temperature treatment period, the faster the time of flowering. When Convallaria keiskei Miq. is naturally grown, the dormancy is broken spontaneously after November 30. For commercial purposes, the growing temperatures were 14-30℃. The leaves and flower stalks of those grown at 27±1℃ were generally grown unproductively, leaving them with no commercia value. The low temperature treatment at 5℃ or 10℃ required a longer period of the low temperature treatments than at 0℃.
