“…Also, we have recently demonstrated that TiO 2 NPs (anatase: rutile) are chronically applied to T. aestivum, decreased maximal and effective efficiency of PSII, net photosynthetic rate, transpiration rate, stomatal conductance, intercellular CO 2 concentration, and starch content (Dias et al 2019). On the other hand, the application of SiO 2 NPs improves the gas exchange performance in Passiflora edulis with an increase of Pn, E, and gs (Costa et al 2018). Overall, our data suggest that low doses of TiSiO 4 NPs play some protective role in photosystem II, not having the negative impacts of TiO 2 NPs.…”

Our knowledge of the bioactivity of silicon titanium oxide nanoparticles (TiSiO4 NPs) in crops is scarce, contrarily to TiO2NPs and SiO2NPs that are used in many industrial sectors, and have emerged in nanoagriculture (e.g., as pesticides or nanofertilisers). To evaluate the potential of using TiSiO4 NPs in nanoagriculture, it is necessary to characterize their potential benefits on crops and the safety doses. Here, we report for the first time the bioactivity of TiSiO4 NPs (up to 100 mg/L) in the model crop lettuce (Lactuca sativa L.) exposed for three weeks (from seeds/seedlings to pre-harvesting phase). The doses applied did not compromise the germination rate, and highly stimulated plant fresh matter. TiSiO4 NPs had beneficial effects on photochemical processes by increasing chlorophyll levels. Effects on photosynthesis are less evident but TiSiO4 NPs (100 mg/L) stimulated the photosynthetic potential, increasing Fv/Fm and ETR when compared to the 50 mg/L conditions. TiSiO4 NPs did not influence the net photosynthetic rate and other Calvin-cycle variables. Soluble sugars and starch levels were overall maintained. In general, this first report on TiSiO4 NPs bioactivity suggests that they did not have a toxic effect, and may be used to potentiate crops’ growth. Principal component analysis (PCA) also shows that despite effects on photosynthetic performance is minimal regarding the control, the 50 and 100 mg/L doses strongly differ, with the lower dose promoting mostly pigment accumulation, while the higher dose slightly stimulates Photosystem II efficiency including the electron transport rate and other gas exchange parameters.

“…O aumento deve-se, principalmente, à camada de cera epicuticular mais desenvolvida, que promove processo importante para prevenir ações de patogênese viral como a germinação e penetração de fungos. Deposições de silício, também, foram observadas em folhas de maracujá que receberam adubações com o elemento (Costa et al, 2018). Figura 2.…”

“…O tomateiro é uma das hortaliças mais cultivadas e consumidas no mundo. O grupo cereja constitui-se como um tomate para mesa com crescente aumento no seu consumo in natura (Costa et al, 2018). Possui tamanho pequeno, forma arredondada ou alongada e cor vermelho-brilhante, lembrando uma cereja (Rodrigues et al, 2016).…”

Avaliou-se o desenvolvimento e a produtividade de tomateiros tipo cereja submetidos a diferentes modos de aplicação de silício, bem como os efeitos dessa adubação sobre o acúmulo de silício nas plantas em cultivo sem solo. Trata-se de pesquisa de campo de natureza quantitativa. Os tratamentos compreenderam: plantas com aplicação de silício foliar, plantas que receberam silício no substrato comercial, plantas adubadas com silício foliar e no substrato comercial, além da testemunha (sem aplicação de silício). O delineamento experimental foi em blocos ao acaso. O fornecimento de macro e micronutrientes ocorreu via fertirrigação. Na folha diagnose realizou-se leitura de clorofila total e clorofila a e b. Analisou-se, ainda, a massa fresca e seca da parte aérea, número e peso dos frutos, inflorescência e altura das plantas. Determinou-se o teor e acúmulo de silício na superfície das folhas coletadas no terço médio da planta e epicarpo do fruto. Os dados obtidos foram submetidos à análise de variância aplicando-se o teste de F e Tukey a 5% de probabilidade, quando os resultados foram significativos. Concluiu-se que a aplicação de silício, independente do modo aplicado, não diferiu da testemunha em todos os parâmetros avaliados. A aplicação de silício foliar favoreceu o aumento de tricomas nas folhas sugerindo maior proteção contra herbivoria. Recomenda-se a realização de outras pesquisas com variadas fontes e concentrações de silício visando identificar a resposta das plantas e estabelecer a ação deste elemento na produção do tomate tipo cereja.

“…The application of Si has beneficial effects on many fruit crops, but there is still little information about the effect of Si on blueberry. The application of Si in passion fruit (Passiflora edulis) increased the photosynthetic rate of the plant (Costa et al, 2018), and in strawberry (Fragaria × ananassa) its improved pulp firmness and increased the level of anthocyanins in fruits (Munaretto et al, 2018).…”

The objective of this study was to evaluate the effect of foliar application of silicon in different blueberry (Vaccinium myrtillus) cultivars. The treatments were installed in a factorial design with six replications, and consisted of three different cultivars (Brightwell, Beckblue and Climax) with or without regular application of silicon via foliar, using silicon oxide at 1.5 g L-1. It was evaluated the following plant attributes: leaf area, chlorophyll fluorescence, and phenylalanine ammonia lyase activity, meanwhile the following postharvest attributes were evaluated: fruit number, diameter and weight, yield, pH, content of soluble solids, titratable acidity, contents of phenolic compounds and anthocyanins, and activity of peroxidase. Vegetative development of blueberry plants in response to Si presented higher yield, leaf area, phenylalanine ammonia lyase activity, and higher chlorophyll fluorescence relationships such as maximum photochemical efficiency and PSII potential activity, as well as less stressed plants, especially in cultivars Climax and Brightwell. For post-harvest physicochemical characteristics, silicon foliar application improved fruit weight and diameter for cvs. Beckblue and Climax, and fruit number for cv. Brightwell. All cultivars, in response to silicon application increased the titratable acidity, the levels of phenolic compounds, the level of anthocyanins, whereas peroxidase activity decreased. The performance of the evaluated blueberry cultivars was better through silicon application, with greater performance of vegetative growth, fruit yield, and fruit quality, especially in cultivar Climax, which was the most suitable in terms in of fruit yield in this study.
