Abstract: EGUCHI T,. KITANO M. and EGUCHI H. Effect of root temperature on sink strength of tuberous root in sweet potato plants (Ipomoea batatas Lam.). BIOTRONICS 23, 75-80, 1994. Eflect of root temperature on sink strength of tuberous root in sweet potato plants was examined at root temperatures of 20 to 32°C under a constant air condition of 28°C and 70 % RH. Dry weight, volume and dry matter content of tuberous root became higher at root temperatures of 24 to 26°C. However, sink strength of tuberous root, which was estimated by its dry weight per unit leaf area, was highest at a root temperature of 24°C possibly because of lower sink activities at lower root temperatures and lower sink capacities with higher respiratory loss at higher root temperatures. Key words: Ipomoea batatas Lam.; tuberous root; root temperature; sink-source relationship; sink strength; translocation
