Crop-climate coupling in greenhouses. characterization and analysis
(2005)The present work analyses the degree of coupling between a greenhouse rose crop and the internal climate as a function of crop characteristics (leaf area index, LAI) and greenhouse climate functions (natural and forced ... -
Differences in leaf gas exchange and leaf characteristics between two almond cultivars
(2013)Leaf chlorophyll content, specific leaf weight (SLW), photosynthetic and transpiration rates, stomatal functioning, water use efficiency and quantum yield were assessed during the kernel filling period for two consecutive ... -
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 ... -
Effect of shading on greenhouse energy balance and crop transpiration
(2012)The purpose of this study was to investigate the effect of greenhouse shading and irrigation water salinity on greenhouse microclimate and energy balance and on crop transpiration and leaf photosynthesis. Experiments were ... -
Effect of two irrigation frequencies on rose flower production and quality
(2005)A better understanding of the effects of irrigation frequency on flower production and quality of rose plants can help to develop optimal irrigation systems. On this purpose experiments were conducted on a soilless rose ... -
Estimating transpiration rate and canopy resistance of a rose crop in a fan-ventilated greenhouse
(2001)The influence of solar radiation (G) and saturation deficit (VPD air) of the greenhouse air on transpiration rate, canopy resistance was investigated on a soilless rose crop (cv. First Red), grown on perlite, during the ... -
Greenhouse cooling by a fog system: Effects on microclimate and on production and quality of a soilless pepper crop
(2006)The influence of greenhouse humidity control on greenhouse microclimate, crop transpiration rate, and yield and fruit quality of a soilless grown pepper crop was studied in a greenhouse located in the coastal area of western ... -
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 ... -
Influence of an aluminized thermal screen on greenhouse microclimate and canopy energy balance
(2003)Greenhouse microclimate, energy savings, and crop transpiration were investigated during winter in a glass-covered greenhouse cultivated with a rose crop and equipped with an aluminized thermal screen. Air temperature and ... -
Influence of misting on the diurnal hysteresis of canopy transpiration rate and conductance in a rose greenhouse
(2000)The aim of this study was to evaluate the effects of greenhouse air humidity control on the transpiration rate (TR) and canopy stomatal conductance (gc) of a soilless rose crop (Rosa hybrida, cv. First Red) grown on perlite ... -
Reducing ventilation requirements in semi-closed greenhouses increases water use efficiency
(2015)We explore an under-appreciated side effect of semi-closed greenhouses: the ability to recover transpired water, thereby increasing water use efficiency. Semi-closed greenhouses are fit with cooling equipment, to limit ... -
Transpiration and canopy resistance of greenhouse soilless roses: Measurements and modeling
(1999)Measurements of transpiration (TR) of a rose crop (cv. First Red) grown on perlite were recorded during the winter of 1998 in a glasshouse located on the coastal area of Eastern Greece. Simultaneously, measurements of solar ... -
Transpiration and energy balance of a greenhouse rose crop in mediterranean summer conditions
(2001)The transpiration rate of a soilless rose crop and its interactions with the greenhouse microclimate and energy balance were investigated during summer conditions in Greece. At this aim, measurements of transpiration (γE ... -
Yearly numerical evaluation of greenhouse cover materials
(2018)The greenhouse internal microclimate, and consequently the plants growth, is formed from the combination of available solar radiation and ventilation. Transpiration and photosynthesis are affected by the PAR levels, as ...
