Influence of vent design on greenhouse microclimate during dehumidification with simultaneous heating and ventilation
(2006)The influence of greenhouse vent configuration on greenhouse microclimate and energy consumption when natural ventilation was used for greenhouse dehumidification was numerically analysed using a computational fluid dynamics ... -
Interactive effects of salinity and silicon application on Solanum lycopersicum growth, physiology and shelf-life of fruit produced hydroponically
(2020)BACKGROUND: Using water with high salinity for plant fertigation may have detrimental effects on plant development and total yield and on the quality of the crop produced. As a possible means to alleviate the negative ... -
Investigation of flow patterns in a greenhouse with mechanically assisted ventilation
(2011)In the present work, the effect of fan ventilation in an arc type tunnel greenhouse under the encumbering action of solar radiation is studied. Results are accrued for the air velocity, temperature, pressure, vapour and ... -
Involvement of lipopeptide antibiotics and chitinase genes and induction of host defense in suppression of Fusarium wilt by endophytic Bacillus spp. in tomato
(2017)Five endophytic Bacillus spp. isolated from surface-sterilized stem tissues of wild Solanaceous species, i.e. Datura metel, Solanum nigrum and S. elaeagnifolium, were screened for their in vitro and in vivo antagonistic ... -
Measurements and modelling of tracer gas distribution in a naturally ventilated greenhouse for pesticide dispersion determination
(2006)In this study numerical and experimental results concerning the dispersion of a tracer gas (N2O) inside an experimental greenhouse with a tomato crop were presented and analyzed. The proposed simulation concerns a greenhouse ... -
Metal nanoparticles: Phytotoxicity on tomato and effect on symbiosis with the Fusarium solani FsK strain
(2021)The effect of copper (Cu-NPs, CuO-NPs), silver (Ag-NPs) and zinc oxide (ZnO-NPs) nanoparticles (NPs) on plant growth, physiological properties of tomato plants and their symbiotic relationships with the endophytic Fusarium ... -
Numerical and experimental analysis of convective heat transfer in a heated greenhouse
(2008)Internal convective flows, resulted from buoyancy forces, in a greenhouse tunnel were numerically and experimentally analysed and discussed. Experiments were performed in an experimental arc type tunnel greenhouse with a ... -
Numerical modelling and experimental measurements of pesticides dispersion in a naturally ventilated greenhouse
(2008)In the present study a commercial CFD code was used in order to investigate the dispersion of a pesticide inside an arch type tunnel greenhouse with continuous side vents. The greenhouse was cultivated with a tomato crop ... -
Performance test of a Na+ accumulation model as part of a decision support system for closed hydroponic systems management
(2012)The recycling of greenhouse effluents in soilless cultivation systems is environment-friendly, since the waste of water and the disposal of nutrients to the environment is drastically reduced or even eliminated. However, ... -
Salinity as eustressor for enhancing quality of vegetables
(2018)Vegetable crops show variable responses to stressful conditions with physiological, biochemical, metabolic and morphological changes that occasionally lead to changes in chemical composition and visual appearance of the ... -
Seed production of bush snap beans (Phaseolus vulgaris L.) in unheated greenhouses following tomato cultivation in relation to the duration of irrigation at various fertilizer levels
(2003)Bush snap beans (Phaseolus vulgaris L.) cv. Larma and Montano were grown in the soil of two unheated glasshouses after tomato cultivation, and irrigated with the following nutrient media: (1) control of water only (0:0), ... -
A serine carboxypeptidase-like acyltransferase is required for synthesis of antimicrobial compounds and disease resistance in oats
(2009)Serine carboxypeptidase-like (SCPL) proteins have recently emerged as a new group of plant acyltransferases. These enzymes share homology with peptidases but lack protease activity and instead are able to acylate natural ... -
Solar radiation distribution in a tunnel greenhouse
(2008)A commercial computational fluid dynamics code was used in order to investigate numerically the effect of solar radiation in an arc type tunnel greenhouse equipped with continuous side vents with a tomato crop. For the ... -
Strong synergistic activity and egg hatch inhibition by (E,E)-2,4-decadienal and (E)-2-decenal in Meloidogyne species
(2016)Recent research has been focused on the potential of plant natural products for the control of nematodes, but few studies are reported on synergistic interactions and egg hatch inhibition properties of botanicals. Herein, ... -
Study of a passive solar heating greenhouse crop grow gutter
(2011)Water-filled transparent polyethylene tubes have been used as a passive solar system in greenhouses in Greece. In this work, the performance of a passive solar heating system used to serve as a crop grow gutter is studied. ... -
Test of a greenhouse covered by polyethylene film that reflects near-infrared radiation
(2012)The aim of this work was to study the effects of a new polyethylene (PE) 'silver' film [with high reflection and absorption in the Near Infrared Radiation (NIR)] on greenhouse microclimate and on growth and production of ... -
