抄録

Eflect of root temperature on sink strength of tuberous root in sweet potato plants was examined at root temperatures of 20 to 32℃ under a constant air condition of 28℃ and 70% RH. Dry weight, volume and dry matter content of tuberous root became higher at root temperatures of 24 to 26℃. 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℃ possibly because of lower sink activities at lower root temperatures and lower sink capacities with higher respiratory loss at higher root temperatures.
