“…This behavior was also observed by Silva et al (2013), who verified an increase in TA contents with the use of Si in strawberry. SS/AT ratio, which expresses a ratio between organic acids and sugars, was also increased with increasing NaCl and Si in the nutrient solution.…”

Silicon (Si) is a mineral element that provides many benefits to plants and may also assist in tolerance to abiotic stresses such as salinity. The aim of the study was to evaluate the use of Si as a possible attenuator of the deleterious effects of salinity on growth and post-harvest of lettuce. A completely randomized design with four replicates was performed in a 3 × 2 factorial, consisting of three salinity levels (1.65, 3.65, 7.65 dS m -1 ) and two levels of silicon (0.0 and 2.0 mM). Salinity reduced all variables related to plant growth. For shoot fresh and dry mass, it was observed that NaCl caused a reduction of 79.80 and 80%, respectively, in comparison to the control. However, parameters related to post-harvest such as titratable acidity, soluble solids and vitamin C increased with salinity. Although not effective in reducing saline stress on plant growth, Si provided improvements in the variables related to lettuce post-harvest. Salinity significantly reduced plant growth in the presence and absence of Si, but provided better post-harvest quality with Si.

“…Soil fertility is also a decisive production factor. Silicon (Si) has been widely studied in recent years (Silva et al 2013, Miranda et al 2018) and, despite not being considered essential to plants, applying this element has increased the resistance to biotic and abiotic stress and, in turn, improved the yield of different crops (Camargo 2016).…”

“…Applying Si to the treatments with a 40 % replenishment of the ETc promoted an increase in the titratable acidity of fruits up to a dose of 100 kg ha -1 , with a decline thereafter. Silva et al (2013) assessed the influence of Si on the quality of strawberries and observed that the application increased the titratable acidity by 3-24 %, if compared to the controls.…”

The netted melon requires special growing conditions, including a protected environment, an adequate staking system and proper water and nutrient management. This study aimed to assess the effect of irrigation levels and silicon doses on the yield and quality of Sunrise hybrid melons, in a greenhouse. A randomized block design was used, with a 5 x 3 factorial scheme and four replications. The first factor consisted of five silicon doses (0 kg ha-1, 50 kg ha-1, 100 kg ha-1, 150 kg ha-1 and 200 kg ha-1) and the second of three irrigation levels (40 %, 70 % and 100 % of the ETc). The results demonstrated that the applied irrigation levels and silicon doses have no influence on the yield traits of melon plants. The irrigation level corresponding to 100 % of the ETc promotes higher values for soluble solids (9.86 ºBrix) and maturation index (114.9) on fruits. The increase of silicon doses up to 200 kg ha-1 also increases the maturation index in the treatment with the greatest irrigation level and reduces this index at the shallowest level applied.

“…Uma das características relacionadas à qualidade de mudas está ligada a sua capacidade fotossintética, sendo proporcionada principalmente pela área foliar, no qual relatam que a elevação da taxa fotossintética culmina em um aumento da produção de fotoassimilados. A clorofila possui grande importância na eficiência fotossintética, influenciando o crescimento e adaptabilidade da planta, sendo esses pigmentos cloroplastídicos responsáveis pela captura de luz solar que é usada na fotossíntese, sendo as clorofilas essenciais na conversão da radiação luminosa em energia química, na forma de ATP e NADPH (SILVA et al, 2013;SILVA, 2014).…”

O objetivo deste trabalho foi avaliar o efeito das diferentes fontes de matéria orgânica incorporadas ao substrato sobre os índices fisiológicos e metabólitos secundários. O experimento foi conduzido no IFES Campus Itapina em um delineamento de blocos casualizados, e os tratamentos consistiram de cinco fontes alternativas de matéria orgânica na proporção de 20% misturadas ao substrato de terra pura. Foram avaliados os teores de clorofilas a, b, total, carotenoides e suas relações através da extração de clorofila, a medida indireta de nitrogênio e clorofila pelo aparelho SPAD, além dos índices de fluorescências obtidos pelo aparelho Multiplex®, no qual mede os índices de flavonóides (FLAV), antocianina (ANT-RG e ANT-RB), clorofila total (SFR-G e SFR -R) e balanço de nitrogênio (NBI-G e NBI-R). Houve aumento nos teores de NBI-G e NBI-R e um decréscimo no FLAV, no substrato com resíduo de indústria de café. Os substratos que usaram como fonte alternativa o lodo de curtume apresentaram maiores valores de flavonóides, sendo inversamente proporcionais ao balanço de nitrogênio. Os índices determinados com o medidor SPAD correlacionaram-se positivamente com os teores de clorofila a, total e carotenóides, entretanto os índices obtidos pelo aparelho Multiplex® só foram significativos quando correlacionados com os valores SFR_R da planta inteira e SFR_G da parte adaxial.
