Abstract

The study was conducted to investigate the characteristics of flower quality and yield of gerbera 'Sunny Lemon' by mutrient solution strength and media of nutrient solution. The plant growth of 'Sunny Lemon' showed the highest values in the media of rockwool and perlite 1: peatmoss 2. Especially the yield of cut flowers for a year was more than 60 flowers and the flower longevity was over 10 days irrespective of nutrient solution concentration in the two media. There were no significant differences of plant characteristics in the nutrient concentration of 1/2 and 1 times, and the mineral nutrient contents showed similar values. Therefore, we recommended the media of perlite1: peatmoss2 with the concentration of 1/2 times for economical use. The rockwool media was not appropriate because of the weak buffer capacity like EC and pH.

본 실험은 배지 및 양액농도에 따른 거베라 'Sunny Lemon'의 생육반응을 바탕으로 절화 품질 및 수확량 등을 조사하였다. 'Sunny Lemon'은 입상암면, 펄라이트와 피트모스가 1:2로 혼합된 배지 (화분지름 18 cm, 화분높이 19 cm)에서 절화 품질이 가장 우수하였다. 또한 2종류의 배지 모두 1 배액과 1/2 배액에서 수확량이 화분당 60 본 이상으로 높고, 절화 수명도 10 일 이상으로 조사되었다. 절화의 특성차이 및 엽의 무기성분 함량에도 처리간에 큰 차이가 없는 것으로 보아 1/2 배액으로도 충분히 1 배액의 효과를 볼 수 있음을 알 수 있었다. 하지만 암면은 양액공급에 따른 EC와 pH 등의 완충작용이 약하다고 평가되고 있기 때문에 적정 배지는 양액에 대한 완충능력이 있는 펄라이트1:피트모스2 혼합배지, 그리고 양액농도는 경제성을 고려하여 1/2 배액이 적정한 것으로 보인다.
