본 연구는 서광 토마토(Lycopersicon esculentum MILL. cv. Seokwang)의 분무경재배시 신소재인 바이오세라믹 분말을 엽면살포(0.2%)와 배양액내에 처리(0.02%)하여 토마토의 생장 및 과실품질 특성을 비교하고자 수행하였던 바 그 결과를 요약하면 다음과 같다. 1. 지상부와 지하부의 바이오세라믹 처리시 대조구에 비해 초장은 감소하였으나 뿌리의 생장은 증가하였다. 2. 바이오세라믹 분말의 엽면살포시 과방의 생장이 대조구에 비해서 약 14% 정도 증가하였다. 바이오세라믹 분말의 지상부와 지하부 처리시 총건물중이 증가하였다. 3. 바이오세라믹 처리시에 T/R율은 대조구에 비해 낮았으며, 순동화율(NAR)과 상대생장율(RGR)은 바이오세라믹을 엽면살포했을 경우에 12.13g/dm2/day와 0.05g/g/day로 가장 높았다. 4. 대조구에 비해 바이오세라믹 분말의 근권처리시에는 총누적생과중 및 건과중이 감소하였으나, 엽면살포시에는 증가하였다. 바이오세라믹 파우더의 근권 및 엽면살포시 대조구에 비해 과실의 수량이 감소하지 않고 당도가 높아졌다.

This experiment was carried out to investigate the effects of new material, bioceramic powder in the nutrient solution(0.02%) and foliar spray(0.2%) on the growth and fruit quality of aeroponically grown tomato(Lycopersicon esculentum MILL. cv. Seokwang). Plant height was lowered, but root growth was increased both treatment of bioceramic powder into the nutrient solution and foliar spray. Cluster growth of tomato plants increased up to 14% over than that of control in the plot of foliar spray with bioceramic powder. Total plant dry weight also increased when bioceramic powder was treated both into the nutrient solution and foliar spray. T/R ratio was reduced by the treatment of bioceramic powder, but NAR and RGR showed the highest in the plot of foliar spray treated with 0.2% bioceramic powder than that of the other plots. Cumulative fruit fresh and dry weight were reduced when bioceramic powder was treated into nutrient solution but foliar spray produced more cumulative fruit fresh and dry weight than that of control. It was shown that treatment of bioceramic powder into the nutrient solution and foliar spray could be improved sugar degree without reducing fruit yields.
