QUANTIFICATION OF THE VENTILATION OF A GREENHOUSE WITH A ROOF OPENING
(1995)
Measurements of air exchange rates were performed in situ in a glasshouse equipped with a continuous roof opening. These measurements were carried out using the decay rate method with N2O as tracer gas. Simultaneously, ...
OVERALL HEAT-TRANSFER COEFFICIENT OF A GREENHOUSE COVER
(1994)
Theoretical considerations concerning the greenhouse energy behaviour during the night, allow us to propose an evaluation method of the overall heat transfer coefficient through the greenhouse cover material as a function ...
Influence of whitening on greenhouse microclimate and crop energy partitioning
(2001)
The influence of whitening a greenhouse roof on microclimate and canopy behaviour was studied during summer in a greenhouse located in the coastal area of eastern Greece. Measurements of microclimate variables, intercepted ...
Air flow and associated sensible heat exchanges in a naturally ventilated greenhouse
(1997)
In order to investigate the three-dimensional nature of the air flow within the greenhouse, a three-dimensional sonic anemometer was used for the direct measurement of air and heat exchange inside the greenhouse and through ...
Interactions between salinity and irrigation frequency in greenhouse pepper grown in closed-cycle hydroponic systems
(2007)
Two different irrigation regimes with two different salinity levels were applied to peppers (Capsicum annum L.) grown in closed hydroponic systems in a glasshouse. The two salinity levels were attained by adding NaCl to ...
Leaf boundary layer conductance in ventilated greenhouses: An experimental approach
(2007)
Improving the design, control and management of greenhouse ventilation systems requires a better insight into the coupling and feedback mechanisms between the crop, the internal atmosphere and the outside atmosphere. The ...
Effect of misting on transpiration and conductances of a greenhouse rose canopy
(2001)
The influence of greenhouse humidity control on the transpiration rate (lambdaE(c)). sensible heat flux (H-c) and bulk stomatal conductance (g(c)) of a soilless rose canopy (Rosa hybrida. cv. First Red) was studied in a ...
Effect of grafting on eggplant leaf gas exchanges under mediterranean greenhouse conditions
(2011)
Grafting is an easier and faster approach than plant breeding to take advantage of both existing resistant plants, especially wild cultivars, and high-bred cultivars. The aim of this study was to investigate the changes ...
