Abstract

This study was performed to examine the high temperature adaptability with CO2 treatment for tomato under the condition of greenhouse cultivation during summer season. The indoor condition of CO2 concentrations were controlled as control, 500 ppm, and 1,000 ppm for the greenhouse with the maximum air temperature of 44℃. With the observation of VPD (vapor pressure deficit) and CWSI (crop water stress index) by leaf-air temperature difference according to CO2 treatment concentration, the plants with the CO2 concentration of 1,000 ppm performed less water stress than those with the CO2 concentrations of control and 500 ppm. The plants without CO2 treatment performed the severest degree of water stress.

여름철 토마토 시설 재비시 CO2 시용에 의한 고온적응성 향상을 구명하고 그 가능성을 검토하고자 실시하였다. CO2 처리 농도를 달리한 온실들(무처리, 500ppm, 1,000ppm)의 기온환경은 유사하였으며, 최고기온은 약 44℃ 수준이었다. CO2 농도에 따른 VPD와 엽기온차에 의한 CWSI(Crop water stress index)변화를 보면 1000ppm처리가 무처리, 500ppm처리보다 수분장해를 받지 않았으며, 수분장해 정도는 1000ppm<500ppm<무처리 순으로 무처리가 수분장해 수준이 가장 높았다.
