Abstract

Growth of cucumber plants (Cucumis sativus L.) was analyzed under three different control regimes of air temperature (i.e., constant-value, two-value and variable-value controls): Desired values were set at 20°C under the constant-value control, at 15°C (night) and 25°C (day) under the two-value control and in a sinusoidal pattern between 15°C and 25°C under the variable-value control. Stem length, leaf area and shoot fresh weight under the two-value control were smaller than those under the constant-value control and the variable-value control, and however percent of dry matter became largest under the two-value control. The largest stem length and leaf area were found under the variable-value control. Thus, it is suggested that the shoot growth can be modified by the control regimes of air temperature, and the variable-value control of air temperature can promote the plant growth.
