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 ...
Calibration and validation of a biological model to simulate the development and production of tomatoes in Mediterranean greenhouses during winter period
(2009)
The aim of this work is to calibrate and validate the adaptation of TOMGRO (TOMato GRowth), a crop growth simulation model for tomato, to the short-term cropping technique and to conditions in Greece. Current practice in ...
Influence of leaf area index on canopy energy partitioning and greenhouse cooling requirements
(2002)
Canopy transpiration, which represents the major cooling process in greenhouses, depends strongly on the crop leaf area index I-LA. In this paper, the influence Of I-LA on canopy and greenhouse energy balance of a soilless ...
Influence of an insect screen on greenhouse ventilation
(2002)
The influence of an insect screen on ventilation rate was experimentally investigated in a multispan glass-covered greenhouse equipped with a continuous roof vent, located at the University of Thessaly near volos in the ...
Temperature gradients in a partially shaded large greenhouse equipped with evaporative cooling pads
(2003)
The main drawback of greenhouse evaporative cooling systems based on cooling pads and extracting fans is the thermal gradient developed along the direction of the airflow. High-temperature gradients of this type can markedly ...
Greenhouse evaporative cooling: Measurement and data analysis
(2001)
Temperature and humidity gradients were investigated during summer in a commercial greenhouse producing cut roses, equipped with a ventilated cooling-pad system and a half-shaded plastic roof In a steady regime, the cooling ...
Effect of two UV-absorbing greenhouse-covering films on growth and yield of an eggplant soilless crop
(2006)
The use of UV absorbing films as greenhouse cover material is spreading out in protected cultivation. Although their effects on pest and disease management have received much attention, few studies focus on their effects ...
Influence of greenhouse ventilation regime on the microclimate and energy partitioning of a rose canopy during summer conditions
(2001)
The influence of the greenhouse ventilation regime (natural or forced ventilation) on the energy partitioning of a well-watered rose canopy (Rosa hybrida, cv. First Red) was investigated during several summer days in warm ...
Influence of aluminized thermal screens on greenhouse microclimate and night transpiration
(2003)
The aim of this work was to characterize the influence of a thermal screen on: the greenhouse microclimate, energy savings and crop transpiration. Measurements were carried out during winter in a glasshouse cultivated with ...
