ISHS Acta Horticulturae 119: III International Symposium on Water supply and Irrigation in the open and under Protected Cultivation

IN SITU PLANT WATER RELATIONS MONITORING FOR GREENHOUSE CLIMATE CONTROL WITH COMPUTERS

Author:   P.A.M. Hopmans
Abstract:
Possibilities are analysed and described for continuous monitoring and calculation of leaf temperature, transpiration rate and leaf water potential and its components. The importance is emphasized of turgor water potential, its role and the way to control this factor in the future with models containing the behaviour of osmotic potential and its adjustment to high and low evaporative demands. Gaps in available numerical information, on which research should be concentrated, are indicated.
