Abstract
At the Shizuoka Agricultural Experiment Station, a control test of muskmelon was carried out wherein the controlled night temperature was automatically lowered by 2 or 4 /sup 0/C from the present temperature when the sunlight level was below the standard, and the humidity was controlled either individually or in combination with the temperature. Concerning the influence of temperature, no bad effect was observed in the constant early half of midnight temperature (18 /sup 0/C) section which was tested from the viewpoint of energy saving. For the test range of 22 - 18 /sup 0/C (winter growing) and 24 - 18 /sup 0/C (autumn growing), there was no significant difference on the fruit weight and shape;but the content of suger was found better in the complex modified temperature section of 22 - 18 /sup 0/C (winter growing) and 24 - 22 /sup 0/C (autumn growing). As for the humidity-added section, the fruit grew bigger, but the sugar content was significantly reduced. Optimal target value of control was estimated at 80 +-5 % daytime and 90 % night-time.
