“…In general terms, the agroclimatic results corroborate with Gama et al (2017), who working with shade screens for the production of cherry tomatoes in the same region of the present research, identified microclimatic changes in the environments, however, with greater changes for solar radiation, whereas, the average temperature did not vary in any way significant.…”

Performance of crisphead lettuce cultivars under protected environment in different times of production 1The objective of this work was to evaluate the behavior of Crisphead lettuce as a function of production seasons under different forms of protected environment. Two experiments were carried out in the field at different times: September to December 2017 and June to August 2018, in a randomizaed blocks desing, in a 4 x 7 factorial scheme, the first one being production environments under shade nets: red screen, chromatinet ® screen, black screen and full sun, and the second, lettuce cultivars: Winslow, Irene, Balsamo, Rafaela, Iron Wood, Great Lakes and Delícia. The harvest was carried out at forty-two days after transplanting, where the following variables were analyzed: stem length (cm), total production and commercial productivity (t.ha -1 ). The data were submitted to analysis of variance, and a joint analysis was performed to analyze the treatments effect, then the means were compared by the Scott-Knott test, at 5% probability. The microclimate was altered in the shaded beds, which affected the cultivars development. The cultivation in protected environment provides higher productivity of Crisphead lettuce from September to December, at that time the cultivars Balsamo and Delicia were highlighted under chromatinet ® . In the period of mild temperatures, a better performance was observed for cv. Balsamo in full sun.

“…It was due to higher shading level decreased sugar content of tomato fruit (Kirschbaum, 2011). The high temperature was well known to influence fruit maturity and growth (Gama et al, 2017). Besides, a previous study reported total sugar content in five genotypes of tomato.…”

Cherry tomato (Solanum lycopersicum var. cerasiforme) from family Solanaceae is an important source for vitamins and other minerals. The demand for tomatoes therefore increases due to the changes in the lifestyle of the food intake among ordinary people who are aware of their nutritional intake. Climate change is nevertheless the greatest treat that can reduced the tomato production. Cultivating indoor using greenhouse is one of the solutions to mitigate this problem. The biggest constraint in tropical climate for greenhouse cultivation, however, is solar radiation and temperature. This study was therefore intended to evaluate the growth, physiology, yield and quality of tomato under two systems of greenhouse; Smart Greenhouse (SGS) versus Conventional Greenhouse (CGS) system. Cherry tomato was grown in two greenhouses at three different shading levels of (0, 50 and 70 percent). SGS received around 800 ppm of CO2 while CGS has been designated as control. The experiments with six replications were carried out in nested design. All the data were compared and subjected to Analysis of Variance (ANOVA). As a results, growth, physiology, and tomato yield were reduced due to high temperature inside SGS under elevated CO2. Additionally, high temperature (32-35 o C) inhibited the assimilation of photosynthetic carbon. Thus, fruit setting was delayed thereby reducing yield production. Upon enrichment, vapor pressure deficit (VPD) decreased under elevated CO2 and lycopene under shaded area showed 52% and 25% respectively higher compared to CGS. Overall, elevated CO2 in tropical climate inside greenhouse influences temperature increase that have reduced growth performance, physiology, yield and quality of cherry tomato.

“…As telas de coloração vermelha transferem mais a luz do espectro nas ondas vermelho e vermelho distante e difundem a luz que passa através da malha, sendo eficiente no desenvolvimento da planta (LI, 2006). Além disso, independente do fator de sombreamento, a malha vermelha proporciona maior transmitância de radiação fotossintéticamente ativa (RFA) para o interior do ambiente de cultivo (GAMA et al, 2017).…”

A rúcula é uma hortaliça de porte herbáceo da família Brassicaceae, originária da região do Mediterrâneo e na última década, tem sido cultivada geralmente em ambiente protegido. Desse modo, o objetivo deste trabalho foi avaliar características agronômicas, em plantas de rúcula cultivadas em telados cobertos com sombrite nas cores preto, vermelho e prata a 50% de sombreamento e também plantas a pleno sol no inverno. O experimento foi conduzido em delineamento de blocos ao acaso, em esquema fatorial 4 x 2. O primeiro fator foi constituído de quatro ambientes de cultivo (pleno sol, sombrite 50% nas cores vermelho, preto e prata. O segundo fator por duas cultivares de rúcula (cv. Folha Larga e cv. Cultivada) e quatro blocos. No período de inverno, as cultivares de rúcula apresentaram produtividade variando de 1,84 a 3,23 kg m², para uma colheita aos 40 dias após a emergência (DAE). A cv. Folha Larga cultivada a pleno sol e sob sombrite vermelho, de modo geral, apresentou melhor desempenho agronômico que a cv. Cultivada no inverno. O sombrite vermelho proporcionou melhores resultados para as características área foliar, massa de matéria seca da parte aérea, altura, diâmetro do coleto e produtividade para a cv. Cultivada.
