본 연구는 장미 ‘Bubble Gum’에 대한 수확 후 LED 광 환경 과 살균제 Azoxystrobin 보존용액 처리 시 절화품질에 미치는 영향을 구명하고자 수행되었다. 광은 백색 LED와 유색 LED (red:blue=5:1)로 처리하였고, 보존용액은 수돗물(tap water, TW)과 Azoxystrobin 0.05 mL・L-1를 처리하였다. 백색 LED처 리의 절화수명은 TW, Azoxystrobin처리구 각각 9.6일, 9.7일 로 LED 광과 보존용액 처리 간의 유의차가 없었다. 유색 LED 처리의 절화수명은 TW처리구가 13.6일, Azoxystrobin처리구 가 9.8일로, 유색 LED 처리구가 대조구(백색 LED + TW)에 비해 절화수명을 4일 연장시켰다. 절화수명 종료 증상은 LED 광 조건과 관계없이 Azoxystrobin처리구는 꽃잎 위조와 청변 화 증상을 감소시켰다. 모든 처리구에서 상대생체중과 수분흡 수율은 각각 처리 후 2일, 4일까지 증가하다 감소하는 경향을 보였다. 수확 직후 대비 처리 6일 후 화색 변화율과 잎의 엽록 소 함량은 수확 직후와 모든 처리구에서 차이가 없었으며, 화 폭증가율도 처리 간 차이가 없었다. 결론적으로 백색 LED + Azoxystrobin 보존용액처리는 절화장미의 꽃잎 위조와 청변화 증상을 감소시키지만, 절화수명 연장효과가 없었으며, 적색 +청색 LED 처리는 장미의 절화수명 연장효과에 효과적이었다.
This study investigated the treatment effect of flower quality on the LED light and vase solution of azoxystrobin on the postharvest of cut rose ‘Bubble Gum’ flowers. The light was treated with white LED and colored LED at a red:blue ratio 5:1, and the vase solution was treated with tap water (TW) and 0.05 mL・L-1 azoxystrobin. In white LED treatment, the vase life was 9.6 and 9.7 days for TW and Azoxystrobin, respectively, which was no significant difference between the LED and vase solution. In the colored LED treatment, the vase life of TW and azoxystrobin treatment was 13.6 and 9.8 days, respectively, which was extended by 4 days compared to the control (white LED + TW). The vase life termination symptoms of azoxystrobin treatment were reduced in petal wilting and blueing regardless of the LED light conditions. In all treatments, the relative fresh weight and vase solution uptake increased and decreased from 2 days and 4 days after treatment. There was no difference between after harvesting and six days on petal color and the chlorophyll content of the leaves. In all treatments, the rate of increase in flower size was no different. In conclusion, white LED with vase solution treatment of azoxystrobin was no effect on extending vase life. The colored red with blue LED treatment extended the vase life of cut rose ‘Bubble Gum’ flowers.
