Elevated Root-Zone Temperature Modulates Growth and Quality of Hydroponically Grown Carrots

摘要: Air and soil temperatures strongly influence the growth quality of crops. However, in root vegetables, such as carrot, few experiments aimed at regulating by manipulating root-zone temperature have been reported. We investigated effect (20°C, 25°C, 29°C, 33°C) on carrot components using a hydroponic system. High for 14 days reduced shoot rootgrowth water content. In contrast, total phenolic compounds soluble-solid content increased tap roots under high-temperature treatment. Root oxygen consumption was upregulated after 7 These results suggest that high induce drought-like stress responses modulate biomass components. treatments administered to hydroponically grown crops may be valuable tool improving increasing value
