초록

양파 plug묘 육묘시 일장조절에 의한 우량묘 생산을 위해 자연일장을 대비로 하여 11.5시간, 12.5시간 및 13.5시간의 일장 하에서 월륜과 창녕대고 품종을 200공 plug tray에 육묘한 후에 직경 16cm pot에 이식하여 16시간의 일장 하에서 재배하였다. 엽수, 엽초경, 초장 및 엽초장은 시기가 경과할수록 증가하였으나 13.5시간 일장에서의 초장과 엽초경은 일장처리 20일 후에는 감소하였다. 일장에 따른 생육은 엽수 및 엽초경은 장일조건에서 생육이 좋았으나 초장 및 엽초장은 장일에서 억제되는 경향을 나타내었다. 장일조건에서 육묘한 것일수록 이식 후에 구가 크고 비대도 빨랐다. 이상의 결과로 볼 때 육묘기간 중의 장일처리로서 도장의 억제 및 우량묘 생산의 가능성을 보여주고 있다.

This experiment was conducted to find out the effect of day length on the production of high quality plug seedlings in onion (Allium cepa L.). Two cultivars, ‘Changnyongdaego’ and‘Wolryun’, were grown to seedlings in 200-cell plug trays under 11.5, 12.5, 13.5 hours and natural day length. These seedlings were transplanted to the pot (16 cm In diameter) and grown under 16 hours day length. Number of leaves and neck diameter showed better growth in the longer than shorter day length treatments, but plant height old sheath length were retarded in the longer day length treatments. Growth such as no. of leaves, neck diameter, plant height and sheath length increased with the passage of day, but plant height and neck diameter decreased by treatment over 20 days with 13.5 hours day length. Bulbing and bulb size of onion after transplanting were enhanced in the seedlings cultured under longer day lengths. From the above results, treatment of long day length during seedling culture in plug tray can control the overgrowth and produce high quality plug seedlings.
