초록

제주에서 무가온 하우스 재배에 적합한 아티초크 품종을 선발코자 'Purple Romagna', 'Imperial Star', 'Green Globe', 'Emerald', 'Italian', 'Carciofo Di Romagna' 품종을 시험재료로 이용하였다. 2004년 10월 5일에 본엽 4매 정도 자란 묘를 무가온 하우스내에 정식하였다. 첫 수확은 이듬해 봄 4월 하순경부터 시작되었는데 첫 수확일은 'Emerald'와 'Imperial Star'가 4월 26일과 27일로 빨랐으며, 대체로 수확은 5월 상순경부터 시작되어 6월 하순까지 가능하였다. 주당 수확 화뢰수는 'Green Globe'가 5.4개 이상으로 가장 많았으며 'Italian께서 1.3개 정도로 가장 적었다. 평균 화뢰무게는 'Imperial Star', 'Green Globe', 'Purple Romagna'에서 $228{\sim}288g$ 정도로 비슷하였다. 10a당 수량은 'Green Globe께서 2,172kg으로 가장 많았으며, 다음이 'Imperial Star'에서 1,947kg이었다. 따라서 난지지역인 제주도에서 아티초크의 무가온 하우스재배에는 수량면에서 'Green Globe'및 'Imperial Star'가 적합할 것으로 판단되며, 10월에 정식하여 재배할 경우 이듬해 4월 하순부터 6월까지 수확할 수 있다.

This study was carried to select artichoke (Cynara scolymus L.) varieties that can be cultivated in non-heated greenhouse during winter in Jeju Island in Korea. Artichoke varieties namely, 'Purple Romagna' (Neseed Co.), 'Imperial Star' (Keithley Williams Seed Co.), 'Green Globe' (Park Seed Co.), 'Emerald' (Ferry-morse Seed Co.), 'Italian' (Unknown), and 'Carciofo Di Romagna' (Lortolano), were raised in a plug tray with 72 cells for two months and transplanted in a non-heated greenhouse on October 5, 2004. The first harvesting of 'Emerald' and 'Imperial Star' were the earliest and April 26 and 27, 2005 respectively. Most of the varieties were harvested from early May to June 2005. The number of head per plant was the highest in 'Green Globe' with more than five heads and the lowest were recorded in 'Italian' with one head or less. The weight of heads per plant was more than 228 g in 'Purple Romagna', 'Imperial Star' and 'Green Globe'. The highest yield was in 'Green Globe' with 2,172 kg/10a, followed by 'Imperial Star' with 1,947 kg/10a. Accordingly, it is considered that 'Green Globe' and 'Imperial Star' are adequate for the high-yield cultivation in non-heated greenhouse in Jeju Island. They can be harvested from the April to June when cultivated from the early October of the previous year.
