Abstract
Earlier research with Saintpaulia and Begonia on heated benches showed that there are differences in crop responses which have consequences for the use of bench heating systems.
In order to find more general plant responses to root-zone heating experiments were carried out with another four crops.
Growth rates of Ficus benjamina and Schefflera arboricola ‘Compacta’ were enhanced on heated aluminium benches.
A great part of the total heating demand can be supplied with these new heating systems as relatively high root-zone temperatures up to 30°C can be used for these crops.
Spathiphyllum and Guzmania ‘Empire’ can also be grown on heated benches, but optimal root-zone temperatures are somewhat lower than the range found for foliage plants.
Bench heating with a root-zone temperature of 30°C reduced number of side shoots and flowering rate for Spathiphyllum, while flower quality was negatively affected for Guzmania at this temperature.
