“…for the fresh and dry mass of the stem, reaching reductions of 59.8 and 97.1%. These results indicate that the application of Si promotes the development in plants under water deficit in function of promoting improvements in nutritional balance, providing a greater accumulation of Si in the cell wall and favoring the accumulation of biomass [28,12].…”

“…The benefit of silicon fertilization on the accumulation of biomass in plants is still controversial, as in Corymbia citriodora, where the fertilization with Si did not have an effect on the fresh and dry masses of the roots and shoot [31]. The application of Si via irrigation water in melon (Cuccumis melo L.) did not have an effect on the accumulation of dry shoot matter and in total plant dry mass [28]. The leaf fertilization of 150 mg L-1 of Si in okra (Abelmoschus esculentus L.) plants under salt stress promoted increases of 40% and 36% in fresh and dry shoot mass and 32% and 25% in fresh and dry root mass, respectively [32].…”

Aims: The study was conducted to evaluate the fluorescence and growth of eggplant under influence of water deficit and silicon doses. Study Design: The design was a randomized complete block design, in a 5 x 2 factorial arrangement, with four replications and one plant per plot, totaling 40 experimental units. Length and Place of Study: The research was implemented between September and November 2016, in a greenhouse of the Center of Science and Technology Agrifood, at the Federal University of Campina Grande (UFCG / CCTA), Campus of Pombal-PB, Brazil. Methods: Doses of 0, 75, 150, 225 and 300 mg L-1 of silicon and the irrigation slides of 50 and 100% of real evapotranspiration - ETr were used, which were obtained by weighing the pots daily in order to keep the weight close to the field capacity. Results: The use of 50% level of the ETr provides reductions of 5.58; 7.92 and 6.84% of fluorescence in the initial, maximum and quantum yield of the photosystem. The fresh and dry mass of the stem presented the maximum productivity (140.8 and 48.1 g) in the plants irrigated with 100% Etr and treated with doses of 106 and 110 mg L-1 of Si. Conclusion: The fluorescence and biomass of the eggplant plants is reduced with the decrease in irrigation level; while the application of silicon does not result in increment in the fluorescence and dry mass of the leaf. The 100% irrigation level of the ETr associated with the application of 108 mg L-1 of silicon resulted in the best results in stem mass accumulation.

“…The curative effect of SiO2 in saline conditions was through breaking seed dormancy and internal phytohormonal regulation (Sun et al, 2021;Lee et al, 2010). SiO2 application in melon under saline conditions also alleviated the harmful effects of salinity by making an encouraging effect on vegetative growth parameters (Gomes et al, 2018). Silicon supplementation in calcium deficiency increased ascorbic acid, total phenol, carotenoid and photosystem II yield, and fresh and dry matter production in arugula plant.…”

Rocket (Eruca vesicaria), a plant from the cruciferous (Brassicaceae) family, whose leaves are eaten as a salad, is also considered a medicinal plant due to its different therapeutic properties. In this study, the effects of silicon dioxide priming (0.5, 1, 1.5 mM SiO2) on the germination and vegetative growth properties of two different rocket cultivars (Geniş Yaprak, Eda) were investigated under increased salt stress conditions (150, 200 mM NaCl). For this purpose, germination percentage (GP), germination index (GI), germination rate coefficient (CVG), mean germination time (MGT) germination rate index (GRI) were calculated as germination parameters. Shoot and root length (mm), leaf width and length (mm), plant fresh weight (g) were measured in seedlings developed from germinated seeds, and seedling vigour index (SVI) was calculated. The effects of SiO2 priming on germination and vegetative growth differed according to the cultivar. In Geniş Yaprak cv., 1 mM SiO2 application had a positive effect on germination parameters both in seeds not applied salt stress and under 150 mM salt stress, and increased the germination rate from 30% to 73%, especially in salty conditions. Under 200 mM salt stress, 1.5 mM SiO2 had a positive effect on germination parameters in same cultivar. Although SiO2 applications in Eda cv. were not effective on germination parameters under stress-free conditions, they had a positive effect on vegetative parameters. Especially, 1.5 mM application dose increased SVI, root and shoot length and plant fresh weight. In both salt concentrations, 1 mM application dose made a slight improvement in germination parameters of Eda cv. The positive effects of SiO2 applications on vegetative growth parameters such as leaves, roots and shoots were determined at different doses for both salt concentrations.

“…Fruits vegetables not accumulate Si as well as rice, but some studies have shown that this element may contribute to increase the photosynthetic rate and plant growth for some species such as eggplant and melon [15,16]. However, there is a lack of work about the interaction between Si and N in horticultural species such as eggplant, in terms of their influence on the accumulation of mineral and total nitrogen in the tissues of the plant.…”

To evaluate the effect of fertilization with N and Si on gaseous exchanges, dry mass, concentrations, accumulations and compartmentalization of nitrogen fractions in eggplant. The experimental design was a randomized entirely design, in a 5 x 4 factorial arrangement with four replications and one plant per plot, totaling 80 experimental units. The experiment was conducted in a protected environment at Center of Sciences and Agri-Food Technology of the Federal University of Campina Grande, Campus of Pombal, Paraiba, Brazil, between July and September 2016. The nitrogen doses applied was 25, 125, 250, 350 and 500 mg dm-3 and four silicon doses was 0, 75, 150 and 200 mg dm-3 both supplied by root. In pre-flowering stage were evaluated growth components; gas exchange, which are: photosynthesis, stomatal conductance, transpiration rate and intercellular CO2 concentration; levels and accumulation of fractions of nitrogen (NO3-, NH4+, and total), and the silicon concentration in the leaves. There was no significant interaction (p >0.05) between the factors nitrogen and silicon doses for any of the evaluated variables. Nitrogen and silicon doses influenced the variables evaluated only independently each other. The nitrogen doses promoted increases in the photosynthetic rate and associated variables, dry matter yield of stem leaves and roots and in the concentration and accumulations of nitric, ammoniacal and total nitrogen in leaf, stem e roots and decrease the concentration of silicon in leaves. The silicon doses increased the leaf area index, the nitrate levels and accumulation in the roots and the silicon content in the leaves. In conclusion, the nitrogen supply increased the photosynthetic rate, dry mass and nitrogen accumulation and decreased the concentrations of silicon in leaf. Silicon did not interfered with growth of eggplant, however increased leaf area index, decreased nitrate levels and accumulations in the roots at lower doses of this element.
