Numerical simulation of thermal behavior of a ventilated arc greenhouse during a solar day
(2010)
In the present study the transport phenomena occurring inside a ventilated arc type tunnel greenhouse are simulated during a solar day taking into account the optical properties of plants only in the photosynthetic active ...
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 ...
Experimental and modelling analysis of pesticide fate from greenhouses: The case of pyrimethanil on a tomato crop
(2012)
The distribution of a pesticide on target and non-target elements of a greenhouse, and its fate after application, was studied. The experiments were performed in a round arched greenhouse with vertical side walls containing ...
Microclimate Distribution in a Greenhouse Cooled by a Fog System
(2012)
The aim of this study was to characterise the microclimate distribution in a greenhouse cooled by a mist system in comparison to the microclimate distribution of a roof ventilated greenhouse. For this purpose, air temperature, ...
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 ...
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 ...
Extension and evaluation of a model for automatic drainage solution management in tomato crops grown in semi-closed hydroponic systems
(2015)
In the present paper, a model previously developed to simulate the course of Na+ accumulation in closed hydroponic systems as a function of plant water consumption was further extended so as to be operative also in semi-closed ...
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 ...
Influence of covering material and shading on the spectral distribution of light in greenhouses
(1999)
The solar photon flux distribution was measured in the range from 400 to 1100 nm under a twin-span glasshouse and under the same glasshouse with blanked roof, external shading net and internal aluminized shade-screen. ...
