| Abstract:
The uptake of water and N, P, Ca, K and Mg in cucumber plants growing at 12°C, 20°C, 28°C and 36°C root temperatures was studied in a closed hydroponic system. The ion content was measured in the roots, leaves and stems. Water uptake, leaf area and total plant growth reached a maximum at a root temperature of 28°C. The uptake of all the nutrients increased sharply when root temperature was raised from 12°C to 20°C. At root temperatures between 20°C and 36°C uptake of P and Ca continued to increase, whereas N, K, and Mg were little affected. | |
