SOME ASPECTS OF WATERSUPPLY IN A GLASSHOUSE

DR. J.F. BIERHUIZEN
The relation between watersupply, soil moisture content or soil suction on one hand and plant response on the other hand depends on other soil and climatic factors as well. A description has been given of the importance of such factors on water uptake in the liquid phase from the soil via the root, the xylemvessels into the leaf in connection with the water loss in the vapour phase via stomates into the ambient air regarding their gradients and restances involved.

The phase lag between water uptake and water loss by transpiration on various plant aspects such as stomatal opening, relative turgidity, leaf suction and temperature will be discussed in relation to a diurnal cycle, production and conditions prevailing in a glasshouse. The suitability in practical application of various methods in plant response has been shown.
