Abstract

This study aimed to examine cucumber (Cucumis sativus) varieties adaptive to the desert climate by comparing and analyzing the growth, yield, and water consumption. Two long-sized cucumber varieties, 'Gulfstream' and 'Imea' and two medium-sized cucumbers, 'Nagene' and 'Sausan' were cultivated in coir substrate hydroponics under hot and humid greenhouse conditions from March 2 to June 20, 2020. On the 113 DAT, 'Nagene' had the longest plant height and the highest internode number. The marketable fruit number per plant was higher in the medium-sized varieties, which had more internode number. The marketable fruit number was 31.3 for 'Gulfstream', 30.7 for 'Imea', 57.8 for 'Nagene', or 56.0 for 'Sausan' with no significant difference in total fruit weights per plant. The water consumption required to produce 200 g of fruit was lower in the 'Nagene' (2.39 L) with the highest water use efficiency (WUE). Therefore, 'Nagene' variety may have higher adaptability to desert high temperature compared to the long-sized varieties, and it is going to be necessary to verify more medium-sized cucumber varieties.

본 연구는 유럽계 장과형과 중과형 오이 품종을 고온·다습 조건에서 재배하여 품종별 생육과 수량 특성 및 수분소모량을 비교 분석하여 중과형 오이 품종에 대해 사막기후 적용 가능성을 검토하고자 수행되었다. 유럽형 장과종 오이 2품종(Cucumis sativus 'Gulfstream', 'Imea')과 중과종 오이 2품종(C. sativus 'Nagene', 'Sausan')을 연동형 플라스틱온실에서 2020년 3월 2일부터 6월 20일까지 코이어 수경재배로 재배하였다. 개체당 생산한 상품과수는 장과종 'Gulfstream'이 31.3개, 'Imea'가 30.7개, 중과종 'Nagene'이 57.8개, 'Sausan'이 56개로 마디수가 더 많았던 중과종이 상품과수가 더 많았으며 개체당 생산된 총상품과중은 유의차가 없었다. 과실 200g을 생산하기 위해 소요된 물량은 'Nagene'이 2.39L로 가장 적었으며, 수분이용이용효율(WUE)은 'Nagene' 품종이 가장 높았다. 따라서, 상품과수와 물소비량을 고려할때 장과종보다는 중과종인 'Nagene'이 사막 고온 적응성이 더높을 것으로 판단되고 앞으로 더 많은 중과종 품종에 대한 검증이 필요할 것으로 보인다.
