Abstract

Chrysanthemum stock plants were cultivated in aeroponics.
Cutting number and quality in response to the spraying interval and -duration during day and night were tested.
Further trials concerned the temperature of the circulating nutrient solution.

The irradiation-based spraying interval should be limited to about 1.05 J/cm² during the summer season and 4.2 J/cm² during wintertime.
During the night a constant interval of about 30 minutes was sufficient.
Spraying duration should last about 120 seconds in summer and 30 seconds during wintertime.
The response of the plants to the nutrient solution temperature was quadratic and relatively small within the tested range of up to 40 °C. However, temperature of the nutrient solution should be held between 20 and 25 °C.
