Light quality manipulation improves vegetable quality at harvest and postharvest: A review

Effects of Shade Level and Microenvironment on Vegetative Growth, Physiological and Biochemical Characteristics of Transplanted Cucumber (Cucumis sativus)

“…Light quality modification by colored shade nets efficiently decreases temperature compared with black shading. This might be due to the higher content of scattered/ diffuse light (Ilić and Fallik, 2017). The reduction in air temperature during the summer experiments under higher shade levels could be attributed to the light diffusive characteristics and the shaded environment of the black nets.…”

“…Under shade condition, plants undergo morphological changes to maximize light use. Modification of the light spectrum quality and quantity via black and/or colored shade nets can act as a physiological tool to modify the crop micro-climate and enhance plant growth and productivity (Ilić and Fallik, 2017). Plants adapted to shade have greater foliar surface and specific leaf area, thinner leaves, and taller stems compared with plants adapted to strong light (Larcher, 2003).…”

“…Shading nets are intended to reduce solar radiation in order to reduce heat stress especially during summer inside greenhouses. Significant amount of work has been done on the effect of shading materials including shade clothes with varying degree of shading, shade nets, and partially shad screens (Shahak et al, 2008;Stamps, 2009;Semida et al, 2013;Ilić and Fallik, 2017) to reduce the photo inhibition and/or high temperature caused by light. Our studies show that solar radiation and temperature have been strongly affected by shading level.…”

“…Low-cost protected cultivation, such as plastic tunnels and net houses, has the potential to reduce different biotic and abiotic stresses, which affect productivity and quality (Ilić et al, 2015). Netting, is frequently used to protect transplants and other commercial crops from excessive solar radiation, to improve the thermal climate sheltering from wind and hail, and for exclusion of birds and insecttransmitted viral diseases (Shahak, 2008;Kong et al, 2013;Ilić and Fallik, 2017). Significant amount of work has been done on the effect of shading material including shade clothes with varying degree of shading , colored shade nets, and partially shade screens (Li et al, 2000;Buthelezi et al, 2016;Chang et al, 2016;Sivakumar et al, 2017) to reduce the photo-inhibition or/and high temperature caused by light.…”

Effect of shading and grafting on yield and quality of tomato

“…Shade nets are less expensive, and can be used as vertical windbreaks, and horizontally on structures without sidewalls . They provide mixtures of natural, unmodified light and scattered, spectrally modified light . Plants use diffuse light more efficiently than direct light.…”
