Silicon as a mitigator of water deficit stress in radish crop

Avaliação de tubérculos de rabanete (Raphanus sativus) Brassicaceae submetidos a diferentes doses de Si (Plus, GigaMix®)

“…This was observed for the mean mass of the control of 5.98 ± 2.41 g, in the first dose of 13.5 g kg -1 of 7.69 ± 1.07 g and for the highest concentration of 75 g kg -1 with 23.29 g. The average weight of the tuber evaluated showed R 2 = 98.56% of the increment, which also, as expected, Different studies with radishes are available in the literature using different elements, groups of elements in nutritional formulations and products of animal origin such as earthworm humus and bovine, swine and poultry manure (Silva et al, 2015). Our results corroborate those of Lacerda et al (2022) where they used the cultivar Apolo on doses of silicate which provided greater productivity in the radish crop. However, other studies differ from those presented, such as the study by Pohlmann et al (2019) where they evaluated different doses of Si in the foliar application system for variety Vip Crimson Special Selection, where they did not observe a significant increase in the vegetative structure of the plant.…”

“…The researchers obtained a variation between 6.75-8.25 number of leaves, fresh and dry phytomass of the shoot between 8.25-12.0 and 1.50-2.25 g, respectively, for the variety Vip Crimson Selection Especial of radish. Although the study by Lacerda et al (2022) contradicts this study and by Pohlmann et al (2019), as the researchers found a positive effect using a foliar application system. The vegetative gain on the fresh and dry mass parameters of the radish shoot was significant.…”

Experimental Study of the Influence of CH4 and H2 on the Conformation, Chemical Composition, and Luminescence of Silicon Quantum Dots Inlaid in Silicon Carbide Thin Films Grown by Remote Plasma-Enhanced Chemical Vapor Deposition

“…Silicon is the second most abundant element in the earth’s crust and the backbone of the microelectronics industry. , When silicon is reduced to sizes smaller than its exciton Bohr radius (<4.5 nm), it exhibits intense and tunable photoluminescence (PL). Experimental and theoretical studies have shown that quantum confinement effects (QCEs) are largely responsible for the observed PL. − Luminescence from the nanostructured silicon has a vast number of applications.…”
