고온조건하에서 코이어 배지에서 유럽형 가지 품종별 수분소비량, 식물체 생육 및 과실 특성 비교 = Comparison in Water Consumption, Plant and Fruit Growth of Different Europe Eggplant Cultivars in Coir Substrate Hydroponics under High Temperature Conditions

다국어 초록 (Multilingual Abstract)

This study aims to select eggplant cultivars adaptive to the hot temperature period greenhouse climate by water consumption, and growth performance of plants and fruits of different European eggplant cultivars, including ‘Bartok (BA)’, ‘Bowie (BO)’, ‘Black Pearl (BP)’, ‘Ishbilia (I)’, ‘Mabel (M)’, ‘Vestale (VE)’ and ‘Velia (VL)’, in substrate hydroponic cultivation under hot and humid greenhouse conditions. On the 118 DAT, the leaf number and stem dry weight were highest in ‘VL’, followed by ‘M’, and there was no significant difference in leaf dry weight among cultivars. The marketable fruit number per plant was 16.4 for ‘M’, which was higher than other cultivars, and ‘VE’ and ‘VL’ were 8.5 and 8.8, respectively. The weight per fruit was low for ‘M’ at 136 g, and the highest in ‘VE’ and ‘VL’ at 332 and 281 g, respectively. There was no significant difference in fruit production per plant. In this study, ‘M’, which has high water use efficiency and a large number of fruits, and ‘VL’, which required less quantity to water consumption for producing 200 g of fruit and had a high product weight, will have excellent adaptability in the UAE greenhouse condition.

본 연구는 고온기 온실 환경에 적합한 가지 품종을 선발하기 위해 유럽형 가지 ‘Bartok(BA)’, ‘Bowie(BO)’, ‘Black Pearl (BP)’, ‘Ishbilia(I)’, ‘Mabel(M)’, ‘Vestale(VE)’, ‘Velia(VL)’ 7품종을 고온 다습한 온실환경에서 코이어 배지경에서 재배하였을 때, 수분소비량, 식물체 생육 및 과실 특성을 비교하였다. 정식 후 118일에 엽수와 줄기 건물중은 ‘VL’에서 가장 높았고 ‘M’이 그 뒤를 이었으며 엽 건물중은 품종별 유의차가 없었다. 주당 과실수는 ‘M’이 16.4개로 다른 품종보다 많았고, ‘VE’와 ‘VL’이 각각 8.5, 8.8개로 적었으며, 과실당 생체중은‘M’이 136g으로 낮았고, ‘VE’와 ‘VL’은 각각 332, ‘VL’ 281g으로 가장 높았다. 주당 과실 생산량은 품종별 유의차가 없었다. 본 연구의 결과를 종합하여 볼 때 수분이용효율이 높고 과실수가 많았던 ‘M’과 과실 200g 생산에 소요된 물량이 적고, 상품과중이 높았던 ‘VL’이 UAE 온실환경에서 적응력이 우수할 것으로 판단된다.
