“…Coffee seedlings absorbed more Si when it was added to the solution. According to Hattori et al (2005), although Si is an abundant element in nature, its availability to plants in soil solution is usually low, thus its uptake is reduced, especially for dicotyledons. However, Mitani & Ma (2005) have found increased absorption of Si in tomato plants subjected to greater concentrations of this element, which in this study was also confirmed for coffee.…”

“…The leaves become more erect, favoring the incidence of light, greater CO 2 uptake and decreased excessive perspiration, allowing increased photosynthetic rate (Hattori et al, 2005;Ma & Yamaji, 2006). Other indirect effects of Si in the plant include: reduced toxic accumulation of iron and manganese and other heavy metals, like aluminum, and increased phosphorus uptake (Zhu et al, 2004).…”

RESUMO Crescimento e absorção de nutrientes pelo cafeeiro cultivado em solução nutritiva com e sem adição de silícioA adubação silicatada do cafeeiro promove alteração da nutrição da planta e de seu crescimento. Assim, a determinação da absorção de silício e sua influência na absorção de macro e micronutrientes pelas plantas são essenciais para avaliar as implicações deste elemento na fisiologia vegetal, bem como no manejo adequado da cultura. O objetivo deste trabalho foi avaliar a absorção de silício por plantas de café e seu efeito no crescimento e na absorção de outros nutrientes. A pesquisa foi conduzida em casa de vegetação do Departamento de Fitotecnia da Universidade Federal de Viçosa, em Viçosa, Minas Gerais, Brasil. O delineamento utilizado foi o inteiramente casualizado, com dois tratamentos (com e sem adição de silício) e três repetições, cada uma delas composta por três plantas. Foram retiradas alíquotas, a cada três dias, das soluções nutritivas e avaliadas as quantidades de silício e potássio absorvidas, bem como o consumo de água por plantas de café, além da concentração de OH -na solução nutritiva. Ao final de 33 dias, as plantas foram avaliadas quanto à massa de matéria fresca e seca de folhas, raízes e caule; altura da parte aérea e comprimento Growth and nutrient uptake of coffee seedlings cultivated in nutrient solution with and without silicon additionIn recent years, the application of silicon (Si) in crops, including coffee, has become a common practice. The objective of this study was to assess the silicon uptake by coffee seedlings and its effects on plant growth, water and macro and micronutrient uptake. The research was conducted using nutrient solution in a greenhouse at the Departamento de Fitotecnia da Universidade Federal de Viçosa, in a completely randomized design with two treatments (with and without silicon) and three replications. Each plot consisted of three plants grown in a 800 mL vessel containing the treatment solutions. At every three days, water consumption, the concentration of OH -and the depletion of Si and K were assessed in the nutrient solutions. After 33 days, the plants were assessed with regard to their fresh and dry weight of leaves, roots and stem, shoot height and total length of the plant (shoot and root). Number of leaves and internodes, and the content and accumulation of silicon, macro, and micronutrients were also determined. The consumption of water, the amount of potassium uptake and, biomass accumulation were greater in plants grown in solution without silicon addition. However, the concentration of OH -in the solution and the amount of silicon uptake were greater in plants grown in solution with added silicon. Silicon accumulation was greater in leaves than in stem and roots. Silicon decreased coffee plant accumulation of phosphorus, potassium, calcium, zinc, copper and iron.

“…A aplicação de silício (Si) tem sido benéfica a diversas culturas, principalmente as consideradas acumuladoras de Si, como o arroz, cana-de-açúcar, cevada, milho, sorgo e trigo (GUNES et al, 2007;HATTORI et al, 2005;LIMA et al, 2011). Entretanto, plantas dicotiledôneas, consideradas não acumuladoras de Si, como tomate, pepino (LIANG et al, 2005), café (REIS et al, 2008), girassol (GUNES et al, 2008), feijão caupi (MALI; AERY, 2009), batata (CRUSCIOL et al, 2009;PULZ et al, 2008) e tremoço (ABDALLA, 2011) também tem respondido à aplicação de Si.…”

“…As respostas à aplicação de Si são potencializadas quando as culturas são submetidas a algum tipo de estresse (ABDALLA, 2011;GUNES et al, 2007;HATTORI et al, 2005;LIMA et al, 2011;MA, 2004). O Si tem sido associado, indiretamente, ao aumento no teor de clorofila e da capacidade fotossintética, a redução na transpiração e aumento na absorção de nutrientes (ÁVILA et al, 2010;GUNES et al, 2007).…”

RESUMO -A aplicação de silício (Si) é benéfica às plantas. Porém, existem dúvidas sobre a eficiência do seu fornecimento via foliar. Objetivou-se com este trabalho avaliar o efeito da aplicação de Si via foliar, na forma de ácido silícico estabilizado (fonte recém-desenvolvida), na nutrição e na produtividade das culturas da soja, feijão e amendoim. O delineamento experimental para cada cultura foi em blocos casualizados, com quatorze repetições. Os tratamentos foram: controle (sem aplicação de Si) e aplicação de Si via foliar, na dose de 2 L ha -1 do produto Silamol ® (0,8% de Si solúvel como um concentrado estabilizado de ácido silícico). A dose de Si foi parcelada em quatro aplicações. A aplicação via foliar elevou os teores de Si, proporcionando aumento do número de vagens e da produtividade de grãos das três culturas. O incremento foi da ordem de 14; 15 e 9,6%, respectivamente, para as culturas da soja, feijão e amendoim. Palavras-chave: Glycine max. Phaseolus vulgaris. Arachis hypogaea. Silício. Minerais na nutrição.ABSTRACT -The application of silicon (Si) is beneficial to plants. However, there are doubts about the efficiency of foliar application. The objective of this work was to evaluate the effect of foliar application of Si, in the form of stabilized silicic acid (a newly developed source), on the nutrition and productivity of crops of soybean, common bean and peanut. The experimental design for each crop was of randomized blocks with fourteen replications. The treatments were foliar application of Si at a dosage of 2L ha -1 of Silamol ® (0.8% soluble Si as a stabilised concentrate of silicic acid) and a control (without the application of Si). The Si was divided into four applications. Foliar application increased the Si content, providing an increase in the number of pods and a higher seed yield in all three crops. The increase was around 14; 15 and 9.6%, respectively, for the soybean, common bean and peanut.

The addition of silicon is known to produce satisfactory results in several types of plant cultures. However, there are no reports on the effects of addition of silicon to yam (Dioscorea spp.) micropropagation culture medium. The objective of the present study was to evaluate the effects of different silicon concentrations and sources on the growth characteristics of yam plants cultivated in vitro.Three sources of silicon were tested: potassium silicate, calcium silicate, and sodium silicate, each at concentrations of 0.0, 0.5, 1.0, and 2.0 mg L -1 , in all possible combinations. The experimental design was entirely randomized in a 3 × 4 factorial scheme with four replicates and twelve plants per treatment. The 2 mg L -1 sodium silicate supplement yielded the highest number of leaves (7.0) whereas the 1 mg L -1 sodium silicate produced the longest shoots (4.02 cm). Calcium silicate and potassium silicate yielded the highest fresh weight (0.2835 g and 0.2627 g, respectively). Overall, silicon promotes better plant development, with calcium silicate yielding the highest fresh weight. For in vitro yam cultivation, sodium silicate concentrations ranging between 1-2 mg L -1 are ideal.
