Verbatim
e1“Corn salad plants [ Valerianella locusta (L.) Laterr., cultivar Gala] were grown at three root temperatures (15, 20, and 25 °C) in a floating system”
e2“Results showed that growing conditions at 20 °C of the nutrient solution led to the best plant performance in terms of yield, nitrate content at leaf level, root biomass, leaf area, and greenness”
e3“with positive effects on postharvest quality, i.e., less rapid leaf loss of greenness and leaf fresh weight (FW) loss during conservation at 4 °C”

Other claims from this paper (6)
- Intervention effect Growing at 20 °C nutrient solution temperature gave the best plant performance in yield, nitrate content at leaf level and root biomass.
- Intervention effect Growing at 20 °C nutrient solution temperature gave the best plant performance in leaf area and greenness.
- Intervention effect The 20 °C nutrient solution temperature enhanced the functionality of nutrient acquisition mechanisms.
- Intervention effect Corn salad grown at 15 °C showed minor growth.
- Intervention effect The nutrient solution at 25 °C caused stress and affected quality and yield negatively.
- Recommendation For hydroponic cultivation, a growing-medium temperature close to the surrounding air temperature seems suitable.
