아티초크는 가을에 정식하여 겨울철 월동 중에 화아분화가 이듬해 5월경에 수확이 가능하다. 본 시험은 아티초크 육묘 중 저온처리를 하여 생산시기를 7월로 늦추고자 수행하였다. 시험품종은 '그린글로브' 및 '임페리얼스타'를 이용하였다. 파종은 72공 플러그 트레이를 이용하여 2월 10일에 파종하였고 4주간 $17^{\circ}C$에서 육묘한 후 3, 6, 9, $12^{\circ}C$에서 4주간 육묘하였으며 4월 8일에 노지 포장에 정식하였다. 재식거리는 이랑폭 150cm에 주간거리 50cm(1,523주/10a), 1조식으로 하였다. 온도 처리별로는 $6^{\circ}C$ 처리에서 화뢰 발생이 63%로 가장 많았고 $12^{\circ}C$에서는 33%로 가장 낮았으며 무처리의 경우는 5%의 화뢰가 형성되어 저온에 민감한 품종임을 알 수 있었다. '그린글로브' 품종의 경우 $9^{\circ}C$에서 화뢰 형성율이 가장 높아 28%였고 $12^{\circ}C$에서는 10%로 가장 낮았으며 무처리의 경우는 화뢰가 전혀 형성되지 않았다. 화뢰중은 '임페리얼스타' 품종이 97g 내외였고 '그린글로브' 86g 내외로 자랐다. 수량은 '임페리얼스타'에서 215kg, '그린글로브'에서는 108kg을 보였다.

This study was conducted to produce heads of artichoke in July in Korea. The artichoke was planted in the Autumn and it could be reaped heads of artichokes in late of May in Korea. It can inform us that the artichoke need under some low temperature during the Winter to open flowers. In order to harvest heads of artichoke in the Summer two kinds of cultivar 'Green Globe' and 'Imperial Star' those were grown for 4 weeks in green house of $17^{\circ}C$ which were treated at 3, 6, 9 and $12^{\circ}C$ chamber for 4 weeks and then planted the 8th April. Plant distance was $150{\times}50$ cm. After 3 months most of artichoke of 'Imperial Star (IS)' made heads. Especially, the artichokes 'IS' were treated at $6^{\circ}C$ made heads 63% of plants but those at $12^{\circ}C$ made heads 33% and the artichokes (no treatment at low temperature) grown in greenhouse at $17^{\circ}C$ for 8 weeks made heads 5% of plants. 'Green Globe (GG)' made heads 28% of plants at $9^{\circ}C$ and 10% at $12^{\circ}C$, and 'GG' grown in greenhouse at $17^{\circ}C$ for 8 weeks never had made any head. The weights of head were 97 g and 86 g in 'IS' and 'GG' respectively. The yield of heads were 215 and 108 kg/10a in 'IS' and 'GG' respectively.

문제 정의
The results obtained have often led to contrasting conclusions showing that cold requirements vary greatly in relation to genotype and environment. The purpose of this study was to evaluate the possibility of reducing the negative effect of late sowing on harvest time and yield by improving the effectiveness ofchilling seedlings in new seed grown hybrids.

The chamber had LED (Light Emitting Diode) lights and 16 hours day and 8 hours night per a day, The LED formed white light with 40 µmolm−2s−1.
, 2000). The seeds were sowed in 72 holes plugtray in the greenhouse with 17℃ and grown for 4 weeks until the stage of 3th~4th true leaf before moved into 3, 6, 9, and 12℃ chamber for 4 weeks and then hand-transplanted in the open field. The chamber had LED (Light Emitting Diode) lights and 16 hours day and 8 hours night per a day, The LED formed white light with 40 µmolm−2s−1.
These studies explored yield differences by variety, efficacy of both natural and controlled vernalization techniques, and overall potential to produce globe artichokes in Jeju Island.
