준고냉지 숙근 안개초 가을 절화작형시 적심시기 및 절위가 생장 및 개화에 미치는 영향

준고냉지 안개초 가을-초겨울 절화 작형에서 정식 후 적심시기 및 절위를 달리하여 생육 및 개화에 미치는 영향을 검토하였다. 적심 시 근활력과 엽록소 함량은 적심시기가 늦을수록 높아지는 경향이었고, 초장, 엽장 생장속도는 4-5마디보다 7-8마디 적심이 빨랐다. 7-8마디 적심에서 출뢰 및 개화가 빠르고, 화경장과 마디수는 감소하였으며, 출뢰한 분지수는 적심시기가 빠를수록 많았다. 적심시기가 늦을수록 절화장이 크고 기형화 발생과 비원추화서율은 감소된 반면, 로젯트 발생률은 증가되었다. 절화량은 적심시기가 빠르고 7-8마디 적심에서 많았다. This study was carried out to investigate the effects of pinching time (done 7, 14, and 21 days after transplanting on July 10) and node position (4-5 or 7-8 ea node were left) on growth and flowering of Gypsophila paniculata on autumn to early winter cultivation in subalpine area. The root activity and chlorophyll content on each pinching time increased with pinching time being delayed. The growth rate of plant height and leaf width was faster at 7-8th node pinching. The time of flower budding and blooming was advanced, but flower stalk length and node number decreased at 7-8th node pinching. With the time of pinching being delayed, the number of flower budding lateral shoot, the incidence rate of flower malformation and nonpaniculata inflorescence was reduced, whereas rosette rate was increased. Yield was high as pinching time was earlier at 7-8th node. KCI Citation Count: 5
