“…In 2013 and 2015 (sunnier years than 2014) Ly and β-Car contents in the flesh were higher in fruits from the F1 polytunnel than F2, which transmitted 4 times lower UV-A and almost completely excluded UV-B radiation. It was shown that the effects of UV radiation on Ly and β-Car accumulation (stimulative or inhibiting) depend on intensity, duration, and quality of light (Giuntini et al, 2005;Dorais et al, 2008;Bian et al, 2015;Ilić et al, 2015). For example, Guintini et al (2005) reported a positive effect of UV-B radiation on total Ly content in one tomato hybrid, while there was no effect in the other.…”

Tomato (Solanum lycopersicum L.) is among the economically most important vegetables in Europe, valued for its bioactive properties due to significant contents of vitamins, carotenoids, and phenolic compounds. In this study, the tomato cultivar Big Beef F1 was grown in the open field (OF) and under polytunnels in central Serbia during 3 years. Polytunnels were covered with two foils (both with 57% reduced photosynthetic active radiation, PAR) differing in UV-A and UV-B transmittance. The aim of our work was to determine the influence of light conditions on accumulation of phytonutrients (carotenoids and phenolics) in the peel and flesh of ripe tomato fruits. The amount of effective antioxidants, caffeic acid, and quercetin (phenolics with ortho-dihydroxy substitution) in the peel was the highest in tomato fruits grown in the OF (maximal PAR and UV-A and UV-B radiation). Moreover, the content of leaf epidermal flavonoids was the highest in the OF. The content of lycopene and β-carotene in the flesh of tomato fruit was higher under the polytunnel with higher UV-transmittance. Our results showed that selection of the right light conditions (quality and intensity) for tomato production has a significant effect on the accumulation of beneficial phenolics and carotenoids.

“…In traditional vegetable-producing regions, pepper cultivation in a protected environment has expanded to prevent seasonality in the availability of fruit. Low-cost plastic tunnels are still very commonly used for pepper cultivation in Serbia (Ilić et al, 2015). Overheating could be a serious problem in these tunnels considering high summer temperatures.…”

“…The use of shading nets has also become very popular in Serbia due to the very high (35~40°C) temperatures in the summer season (Ilić et al, 2011;Milenković et al, 2012). The netting is either applied by itself over net-house constructions, or combined with greenhouse technologies (Ilić et al, 2015). Temporary shading, applied only during sunny periods, is considered to be less deleterious than constant shading.…”

The concept of photo-selective netting was studied in a sweet pepper (Capsicum annuum L.) cultivar 'Cameleon' from summer cultivation in south Serbia (under high solar radiation 910 W m -2 , with a photosynthetic photon flux density of 1661 µmol m -2 s -1 ), under four different coloured shade-nets (pearl, red, blue and black) with 40% relative shading. The aim of the study was to determine how different environmental control technologies, coloured shade-nets as net house or plastic-house integrated with coloured shade-nets, could influence plant parameters, production and quality traits in pepper fruits. Shade-grown leaves generally have higher total chlorophyll and carotenoid content than control leaves. Pericarp fruit thickness was significantly higher in peppers grown under red net house (4637.10 µm) and black net house (4609.32 µm) compared to the open field -control (3116.19 µm). The highest concentration of total soluble solids (TSS) was detected in pepper fruits grown under the open field conditions (8.03%). Pepper fruits grown in plastic tunnels had significantly lower TSS content (6.58%). Total acid (TA) content was 0.19 in the control and 0.25 in pepper fruits grown under red nets. The highest concentration of vitamin C was detected in peppers grown in plastic tunnels integrated with red coloured nets (175.77 mg 100 g -1 ). These results show that red and pearl photo-selective nets create optimal growing conditions and increase the total fruit yield as well as the number of fruits with fewer physiological disorders and with thicker pericarp. Photoselective pearl and red nets can be recommended for sweet pepper 'Cameleon' with respect to quality and bioactive compound and can furthermore be implemented in protected cultivation practices.

“…In addition to photosynthesis, there are many other aspects of plant growth most affected by light: chlorophyll synthesis, photoperiod, photomorphogensis, phototropism and photo inhibition (Taiz and Zeiger, 2010). 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).…”
