Abstract

This study was carried out to investigate the effect of shading (50% or not) and pruning height (3cm, 6cm, and 9cm) of remained above-ground plant part on shoot emergence aspect, mortality rate, flowering and cut flower characteristics of two years old Gypsophila paniculata plants. Days to shoot emergence (80%) advanced, emerged shoot number increased and mortality rate surveyed on late October decreased in 50% shading treatment. In addition to, mortality rate decreased, as above-ground plant part was highly pruned. Blooming was earlier with highly pruning the remained above-ground pan and under non-shading condition than shading. Growth traits such flower stalk length, primary branches number, stem diameter, and cut flower yield were the best and also non-particulate rate and rosette formation rate were the lowest in pruning height of 9cm under non-shading condition.

2년생 안개초의 안정적인 월하(越夏)를 위해 1차 절화 수확 후 차광여부 및 잔존 지상부 절단 높이에 따른 고사주율, 개화 및 절화특성을 조사하였다. 차광처리에서 신초 발생소요일수가 짧고 발생 신초수도 많았고 고사주율은 낮은 경향이었으며, 특히 지상부를 높게 절단함으로서 고사주율이 낮아졌다. 개화는 무차광에서, 그리고 지상부를 높게 절단한 처리에서 빨라지는 경향이었고, 화경장, 측지수, 경경, 화수폭 및 절화량 등은 무차광, 9 cm 절단처리에서 가장 우수하였다. 비원추화서율과 로젯트 발생률도 무차광 9 cm 절단처리에서 낮았다.
