“…This result is in agreement with the findings of Goren et al (2011) and Kong et al (2013), but is in contrast with the data of Milenkovic et al (2012) and Selahle et al (2015). On the other hand, performing correlation analysis on prior to sampling average air temperature and dry matter content data separately for the two sampling times, significant positive correlations were found if results of the yellow shade net treatment were disregarded.…”

“…On average of the two sampling times white and yellow shade nets resulted significantly the highest DW based vitamin C content, while the red net treatment and the control had the lowest values (Table 2.). This order of the treatments is in good agreement with the findings of field experiments of Kong et al (2013), Tinyane et al (2013) and Selahle et al (2015), but partly contradicts to results of Milenkovic et al (2012). Latter authors found significantly the highest ascorbic acid concentration under red shade net in plastic tunnels, while the same red net produced significantly the lowest vitamin C value under field conditions.…”

“…Vitamin C contents were affected by both shading and sampling time and also by their interaction. Kong et al (2013) and Nagy et al (2016) also found that shading effect on ascorbic acid content of sweet pepper changed with harvest times. On average of the two sampling times white and yellow shade nets resulted significantly the highest DW based vitamin C content, while the red net treatment and the control had the lowest values (Table 2.).…”

“…Coloured shade nets have increased nutritional value of pepper fruits according to several studies. In Israel Kong et al (2013) reported higher vitamin C contents and increased antioxidant capacity under white net compared to the traditional black one in net house sweet pepper cultivation. In South Africa Selahle et al (2015) also found that white net was more effective in increasing vitamin C and total polyphenol concentrations, and total antioxidant activity than yellow and red nets.…”

Effect of coloured shade nets on some nutritional characteristics of a kapia type pepper grown in plastic tunnel

Sweet pepper is the most important vegetable crop of the Hungarian greenhouse industry. Production of red coloured cultivars, having very high nutritive value, is getting popular recently. Shading of plastic tunnels is a common practice in Hungary, but research about its effects on the nutritional characteristics of sweet pepper has just started. The objective of this study was to investigate the effect of different shading methods (shading paint, white, green, yellow and red coloured shade nets) on some nutritional characteristics of a red coloured kapia type pepper, under Hungarian climatic conditions cultivated in unheated walk-in plastic tunnels. Shade net colour slightly affected radiation and hence temperature conditions of the tunnels; especially ratio of supra-optimal temperature values (32 °C <) was changed. Dry matter content was not influenced by shading method, in contrary to sampling time which had a significant effect on this parameter. Vitamin C and total polyphenol contents were affected by both of these factors and also by their interaction; shading effect on these phytonutrients changed with harvest times. However, total carotenoid content was affected just by this latter factor. Heat stress, higher ratio of supra-optimal temperature values, increased total polyphenol concentration and decreased total carotenoid content. In overall, white shade net resulted sweet peppers with the best nutritive quality, but harvest time had a more pronounced effect on content of nutritive constituents than shade net colour.

“…This behaviour can be explained by scattering caused by twisted wires of RS (HOCMAN & SENTELHAS, 2012). KONG et al, (2013) reported no significant difference in air temperature and humidity under pearl and black screen treatments; however, pearl screen increased not only transmittance of long-waveband light but also light intensity within plant canopy. According to the authors, pearl screen is more effective in maintaining postharvest sweet pepper fruit quality than traditional black one, especially at late-season harvests, when a more radiation scattering is desirable.…”

Effects of light intensity modification by reflective aluminized screenhouse on sweet pepper growth and yield

Sweet pepper is one of the ten most consumed vegetables in world. Although it develops better under protected environment, the cultivation in tropical countries is practiced in open field due greenhouse structure higher costs. Unfortunately, such practice has compromised the crop to reach either best yield or fruit quality. Since production and cost are the most important criteria for agricultural production, we aimed to evaluate reflective aluminized polypropylene shading net influence on sweet pepper (Capsicum annuum L.) growth and production as intermediary alternative for low/middle income producers from Brazilian tropical regions. Sweet pepper Magali R hybrid was cultivated in two environments: FC -field conditions (control) and RS -reflective shading net with 40% shading rate. RS caused reductions in incident solar radiation (SR) and photosynthetically active radiation (PAR) on the amount of 46.3% and 48.3%, respectively. There were no significant changes in temperature and relative humidity recorded for the two environments. In addition, RS allowed best use efficiency of photosynthetically active radiation since it promoted higher values of plant height, leaf number and area index than those reached on FC on the amount of 29%, 22% and 80 %, respectively. Similarly, plants grown under RS showed higher yield and marketable fruits and promoted less loses by sunscald. KEYWORDS:Capsicum annuum L., shading, photosynthetically active radiation, solar radiation use efficiency. EFEITOS DE MODIFICAÇÕES NA INTENSIDADE LUMINOSA POR TELAS REFLEXIVAS NO CRESCIMENTO E PRODUÇÃO DE PIMENTÕESRESUMO: O pimentão figura entre as dez olerícolas mais consumidas em todo o mundo. Embora, ele se desenvolva melhor sob ambiente protegido, seu cultivo, no Brasil, ainda é realizado principalmente sob condições de campo aberto, devido aos altos custos das estruturas fechadas. Infelizmente, tal prática tem comprometido o alcance de melhores rendimento e qualidade dos frutos. Uma vez que a produção e os custos são os critérios mais importantes na produção agrícola, o presente estudo teve como objetivo avaliar a influência de telado de polipropileno aluminizado reflexivo no crescimento e na produção de pimentão (Capsicum annuum L.) como alternativa intermediária para produtores de baixa / média renda das regiões tropicais brasileiras. Pimentão híbrido Magali R foi cultivado em dois ambientes: FC -condições de campo (testemunha) e RStelado reflexivo com 40% de taxa de sombreamento. A tela reflexiva causou reduções na radiação solar incidente (SR) e na radiação fotossinteticamente ativa (PAR) na ordem de 46,3% e 48,3%, respectivamente. Não houve mudanças significativas na temperatura e na umidade relativa do ar registradas para os dois ambientes. O RS permitiu melhor eficiência na utilização da radiação fotossinteticamente ativa, uma vez que promoveu maiores valores de massa por planta, número de folhas e índice de área foliar que em FC na ordem de 29%, 22% e 80%, respectivamente. Da mesma forma, as plantas crescidas sob RS alcanç...
