ISHS Acta Horticulturae 43: Symposium on Cultivation of Flowers under Protection in the Mediterranean Regions
THE CLIMATIC CONDITIONS IN THE HORTICULTURAL GREENHOUSES AT FREJUS |
| Author: | R. Portal |
| Abstract:
Several flower greenhouses have been studied in the Fréjus area. These greenhouses belong to different growers, have been built recently and are used for growing the same variety of rose - "Sonia". The study of the climate in these greenhouses in summer and winter - essentially temperature, humidity and light - enables us to determine the efficiency of the means, e.g. ventilation, heating, shading, watering used by the horticulturist to modify the greenhouse climate. | |
