Abstract

This study was conducted to investigate the effect of highland (Daekwallyung, altitude of 800m above sea level) production of cucumber (Cucumis sativus L.) seedlings for retarding culture in lowland (Kangnung, altitude of 20m above sea level). Cucumbers (cv. Jangilbanbaek, Jeongsunyeoreum and Ginseollok) were raised during 25 days from 31st July to 25th August, and then planted under the rain-shelter at Kangnung 25th August. Mean and minimum temperature during raising seedlings at Daekwallyung, $20.9^{\circ}C$ and $16.1^{\circ}C$ were $3.7^{\circ}C$ and $5.3^{\circ}C$ lower than those of Kangnung, respectively. T/R ratio of the seedlings produced at Daekwallyung was lower than that of Kangnung, but chlorophyll contents were higher. Daekwallyung seedlings were higher female/male ratio compared with seedlings from Kangnung. Marketable yield from cucumber seedlings (cv. Jeongsunyeoreum) produced at Daekwallyung was 32% higher than that of Kangnung. These results showed that cucumber seedling raising place was Daekwallyung for the retarding culture during summer season, particularly, and the best cultivars was Baekchim (cv. Jeongsunyeoreum).

오이의 평난지 억제재배를 위한 고랭지에서의 육묘효과를 구명하고자 본 실험을 수행하였다. 7월 31일에 강릉과 대관령의 비가림하우스 내에서 각각 플러그트레이에 파종한 후 25일간 육묘하여 8월 25일에 강릉의 비가림하우스에 정식하였다. 육묘기간 중 대관령의 평균기온과 최저기온은 $20.9^{\circ}C$$16.1^{\circ}C$로 강릉에 비하여 $3.7^{\circ}C$$5.3^{\circ}C$씩 각각 낮았다. 강릉에서 기른 묘는 생육량은 많았으나 웃자라 보였으며, 이에 비해 대관령에서 기른 묘는 엽록소 함량이 많고 T/R율은 낮아 묘가 건실하였다. 육묘지역별 10절까지의 암꽃 착생률은 강릉에 비해 대관령에서 4 22%가 높았고, 백침계의 경우 대관령에서 육묘한 것이 강릉에 비해 상품수량이 32% 증가되었다. 평난지 억제재배용 오이육묘에 적합한 지역은 고랭지였으며 백침계 오이에서 그 효과가 가장 컸다.
