Abstract
This experiment was carrid out to develop a culture method by sequential highland-lowland cultivation for year-round production of fresh leaves in Ligularia stenocephala. Rootstocks of Ligularia stenocephala cultivated in Daegwallyeong openfield were digged up on late October 2007 and then stored in $-2^{\circ}C$ refrigerator. The rootstocks were monthly transplanted in protected greenhouse in Gangneung from November 2007 to June 2008 for lowland cultivation, and also they were monthly transplanted in rainshelter in Daegwallyeong from June to August 2008 for highland cultivation. The early growth of Ligularia stenocephala transplanted on January 2008 was faster. Most plant of Ligularia stenocephala regardless of transplanting time of rootstock grew over 30cm at the time of first harvesting of leaves till May, while the yield decreased during the summer season. The average plant height of Ligularia stenocephala transplanted on July and August in Daegwallyeong highland was lower than that cultivated in Gangneung lowland during spring season. Using of rootstock stored made it possible to produce in highland from Apr. to Oct. during summer season, and also to produce in lowland from Nov. to May next year. Therefore, the results indicates that sequential highland-lowland cutivation by using of stored rootstock will be capable of yearround production of fresh leaves in Ligularia stenocephala.
