초록

이 시험은 '솔라라' 품종의 종자생산을 위해 분무경 수경재배에 적합한 묘를 구명하고자 2015년 3월 16일 배양순화묘 등 8처리의 묘를 분무경 베드에 정식하여 정식 후 70, 78일에 각각 생육과 수량특성을 조사하였다. 경장은 경삽 15일묘와 배양순화묘가 작은 편이었고 경삽묘의 육묘일수가 늘어남에 따라 길어지는 경향이었다. 생체중도 경삽 40일묘가 주당 122 g으로 가장 무거웠고 무발근묘와 배양순화묘는 가장 가벼웠다. 1차 복지는 경삽 35일묘에서 주당 12.9개로 가장 많았고 2차 복지는 경삽 35일묘, 배양순화묘, 경삽 30일묘에서 많이 발생하였다. 10주당 총괴경수는 배양순화묘가 145개로 많았으나 3~50 g(상품) 괴경수는 경삽 35일묘가 108개로 가장 많았고, 괴경 무게는 경삽 35일묘가 1,947 g으로 가장 무거웠고 다음으로 경삽 30일묘였다. '솔라라' 품종 수경재배 시에는 경삽한 후 30일~35일(경장 15 cm, 마디 12절) 묘로 정식하는 것이 수량성을 높일 수 있었다.

This study was conducted to dentify the optimum plantlet type of 'Solara' potatoes (Solanum tuberosum L.) for growth in an aeroponics system. Plantlets of 'Solara' were transplanted on March 16, 2015 in a greenhouse, and growth and yield characteristics were investigated at 70 and 78 days after transplanting, respectively. Stem length was shorter in plantlet of 15-day-old stem cuttings and acclimatization of culture, and the stem length of plantlets of stem cuttings tended to increase with increasing stem cutting age. The fresh weight of plants was the highest in the plantlets of 40-day-old stem cuttings and the lowest in non-rooted stem cuttings and acclimatization of culture. The highest number of first stolons was obtained in 35-day-old stem cuttings. The number of second stolons was the highest in plantlets of 35-day-old stem cuttings, acclimatization of culture, and 30- day-old stem cuttings. The total number of tubers was higher in plantlets of 35-day-old stem cuttings and acclimatization of culture, and the number of tubers above 3 g was the highest in plantlets of 35-day-old stem cuttings. The weight of tubers above 3 g was the heaviest in plantlets of 35-day-old stem cuttings(1,947 g per 10 plants), followed by plantlets of 30-day-old stem cuttings. These results indicate that plantlets of 30 to 35-day-old stem cuttings could be the best for production of 'Solara' potato tubers in an aeroponics system.
