概要 Dissolved O_2 and CO_2 concentrations in nutrient solution and water uptake rate in intact cucumber roots were examined at different root temperatures of 8 to 28℃ by using the on-line measurements in ...an air-tightened hydroponic system under the controlled environment. The root temperature effects on gas exchange and water uptake in roots were found in the sigmoidal pattern, and the patterns of the gas exchange and the water uptake on root temperature appeared almost parallel with each other: The responses decreased with root temperatures lower than 12℃ and increased with root temperatures higher than 16℃.続きを見る
