this study aimed to determine the effects of different shading ratio and covers on “sultana seedless” table grape quality and storability. grapevines were covered at the veraison stage with 3 shading nets (0, 35, and 75% shading), which were then replaced with covering materials including polypropylene cross-stitch (pc), life pack (lp) and mogul (mg), just before harvest. harvested grapes in al...
In many parts of Iran high light intensities during summer can induce stress in cut flower production under open field and greenhouse conditions. Despite roses prefer sunny places for optimum growth, but in practice some levels of rough shading is applied in greenhouse production to improve the quality of cut flowers. So, it is useful to find the light intensities under which different rose cul...
Viticulture worldwide is threatened by the environmental modification caused climate change. Higher temperature and atmospheric CO2 concentration determine an acceleration of ripening process, which can be detrimental to wine quality. Hence, adaptation mitigation strategies are necessary reduce heat water stress improve qualitative production levels. Amongst all various techniques available, sh...
ABSTRACT Shading is a way of cooling in hot and sunny areas to modify the microclimate improve crop growth. This study aimed evaluate effect shading treatments on eggplant sweet pepper growth, under plastic house conditions, at beginning summer, when there are high temperatures solar radiation intensity. The covers were lifted April nets used May June. treatment improved plant height, vegetativ...
Shading the greenhouses is necessary in summer to reduce the solar radiation load. This however generates a considerable amount of thermal radiation heat load that needs to be removed via cooling systems. This study aimed to evaluate the effect of different shading configurations on the solar and thermal radiation in a greenhouse. Nets at four different locations were employed to shade the roof...
The study was conducted to comparatively investigate the browsing levels of Honamlı, Hair and Saanen goats on saplings in a new forest plantation site for six months. Several treatments (fishing net, shading, food colouring raffia) were applied saplings. Thirty two-year-old goats, including 10 animals each breed used. There statistically significant difference among breeds terms their untreated...
This study evaluated the effects of shading nets with photoselective features, an open-field control. The green-shade net intensity 40% and blue, pearl, yellow-shade 75% were used as netting materials. total radiation photosynthetically active (PAR) transmittance shade analyzed. environment conditions such air temperature, relative humidity canopy temperature measured aid appropriate sensors. T...
