Characterization and analysis of the effects of greenhouse climate control equipment on greenhouse microclimate and crop response
(2011)An overview of the recent scientific and technical advances on issues concerning the greenhouse microclimate, control and management in Mediterranean regions is presented and discussed. Special emphasis is given on the ... -
Chrysanthemum morifolium response to PAR intensity as indicated through electrical signal
(2012)It is well documented that higher plants respond to environmental stimuli producing electrical signals that are in practise the information carriers in intracellular and intercellular communication. Since the amplitude of ... -
Effects of cover optical properties on screenhouse radiative environment and sweet pepper productivity
(2014)The effects of cover optical properties on screenhouse radiative environment and sweet pepper productivity were investigated in a Mediterranean climate (Eastern Greece) under three covering materials (i) a pearl insect-proof ... -
Evaluation of thermal perception in schoolyards under Mediterranean climate conditions
(2015)The aim of this paper was to study qualitatively and quantitatively the thermal perception and corresponding heat stress conditions that prevail in two schoolyards in a coastal city in central Greece. For this purpose, ... -
Greenhouse evaporative cooling: Measurement and data analysis
(2000)Temperature and humidity gradients were investigated during summer in a rose production greenhouse equipped with a ventilated cooling-pad system and a half shaded plastic roof. In a steady regime, the cooling process reached ... -
Heat and mass transfer in a large evaporative cooled greenhouse equipped with a progressive shading
(2005)An experimental study was conducted in a large commercial greenhouse equipped with a fan and pad evaporative cooling system and a half-shaded plastic roof. Experimental measurements were carried out at four different ... -
Microclimate of a pepper crop under screenhouse conditions
(2012)In the present study, the influence of three different shading nets with different colour, shading intensity and porosity on the screenhouse and crop microclimate was experimentally investigated. The experiments were carried ... -
Pepper crop production under shading and insect proof screenhouses
(2014)Aim of this study was to experimentally investigate the effect of three different shading and insect proof nets on pepper crop development and production. Three screenhouses were used; two of them were covered by a 50 mesh ... -
A simple model for ventilation rate determination in screenhouses
(2015)The objective of this work was to study and model the ventilation rate in screenhouses. Thus, microclimate variables and crop transpiration as well as the air velocity were measured in three screenhouses covered by different ... -
Solar radiation distribution in screenhouses: A CFD approach
(2012)In this paper the effect of solar radiation distribution in a typical screenhouse was numerically investigated, taking into account the thickness and aerodynamic properties of the screen and its spectral, optical and thermal ... -
Transpiration and canopy conductance of a pepper crop under screens with different porosity and shading intensity
(2014)In the present study, the influence of three different shading nets with different shading intensity and porosity on the screenhouse microclimate and pepper crop transpiration rate was experimentally investigated. The ... -
Transpiration and photosynthesis of sweet pepper growing under differing screenhouse nets
(2012)The influence of three screenhouse nets differing in colour, shading intensity (SI) and porosity on photosynthesis, transpiration rate and light acclimation of sweet pepper plants was investigated at Velestino (central ... -
Transpiration of a sweet pepper crop under screenhouse conditions
(2012)In the present study, the influence of three different shading nets with different shading intensity and porosity on the screenhouse microclimate and pepper crop transpiration rate was experimentally investigated. The ...
