국내 육성 안개초 신품종 ‘Dream Song’과 ‘Pearl Stars’의 평 야지 농가 현장 보급 확대를 위한 가을∼초겨울 절화 생산작 형 개발을 목적으로 여름철 정식시기에 따른 개화시기 및 절 화 생산성을 조사하였다. 정식에서 개화까지의 소요일수는 두 품종 모두 6월 30일 정식이 다른 정식시기보다 짧았으며, ‘Pearl Stars’가 ‘Dream Song’보다 2∼6일 더 길었다. 화경장, 측지수, 분지수 및 줄기 굵기는 두 품종 모두 정식시기가 늦을 수록 증가하는 경향이었으며, 특히 화경장은 ‘Pearl Stars’가 ‘Dream Song’보다 더 길었다. ‘Dream Song’은 정식시기가 늦 을수록 절화장, 절화중이 증가하고 소화가 커졌으며 절화량도 증가하여 7월 15일 이후 정식에서 절화품질이 우수하고 생산 성이 향상되었다. ‘Pearl Stars’도 ‘Dream Song’과 마찬가지로 정식시기가 늦을수록 절화장이 길고 소화가 커졌으며 절화 생 산량은 증가하다가 7월 30일 정식에서 감소하였다. 따라서 ‘Dream Song’은 7월 15일부터 7월 30일 이내에 정식하여 10 월∼12월 상순 절화 생산에, ‘Pearl Stars’는 6월 30일부터 7월 15일 전후에 정식하여 9월∼11월 절화 생산 작형에 적합할 것 으로 생각된다.

This study was investigated the flowering time and cut-flower productivity according to planting time (June 15, June 30, July 15, and July 30) of new domestic Gypsophila cultivars ‘Dream Song’ and ‘Pearl Stars’ with rooted cutting for the purpose of developing a new cropping system during fall to early winter in an area of plains. Days to flowering, from the planting of rooted cutting to flowering, was shorter for June 30 than for the other planting time, and that for ‘Pearl Stars’ was 2 – 6 d longer than for ‘Dream Song’. The flower stalk length, primary branch number, axillary bud number, and stem diameter increased with the delay in planting time. In particular, the flower stalk length of ‘Pearl Stars’ was longer than that of ‘Dream Song’. In ‘Dream Song,’ cut flower length, fresh weight, and floret size were increased, and yield was promoted with a later planting time. As a result, the quality and quantity of cut flowers in ‘Dream Song’ were improved from July 15 planting. ‘Pearl Stars’ also had a similar tendency as ‘Dream Song’ in the quality of cut flowers; in contrast, the flowering yield increased until July 15, but decreased on July 30. Therefore, it was thought that ‘Dream Song’ should be planted within the period from July 15 to July 30 and then produce cut flowers from October to December, and ‘Pearl Stars’ would be planted within the period from June 30 to July 15 and then produce cut flowers from September to November.
