“…The findings of the present study in conjunction with earlier reports on other pathosystems (Guevel et al, 2007;Rezende et al, 2009) indicated that although both foliar and root application of Si is effective in decreasing the intensity of blast, the root application was more effective compared to the foliar application.…”

Rice blast disease caused by Magnaporthe grisea (Hebert) Barr [teleomorph] is one of the most devastating diseases in rice plantation areas. Silicon is considered as a useful element for a large variety of plants. Rice variety MR219 was grown in the glasshouse to investigate the function of silicon in conferring resistance against blast. Silica gel was applied to soil while sodium silicate was used as foliar spray at the rates of 0, 60, 120, 180 g/5 kg soil and 0, 1, 2, 3 ml/l respectively. The treatments were arranged in a completely randomized design. Disease severity and silicon content of leaves were compared between the non-amended controls and rice plants receiving the different rates and sources of silicon. Silicon at all rates of application significantly (α = 0.05) reduced the severity of disease with highest reduction (75%) recorded in treatments receiving 120 g of silica gel. SEM/EDX observations demonstrated a significant difference in weight concentration of silicon in silica cells on the leaf epidermis between silicon treated (25.79%) and non treated plants (7.87%) indicating that Si-fertilization resulted in higher deposition of Si in silica cells in comparison with non-treated plants. Application of silicon also led to a significant increase in Si contents of leaves. Contrast procedures indicated higher efficiency of silica gel in comparison to sodium silicate in almost all parameters assessed. The results suggest that mitigated levels of disease were associated with silicification and fortification of leaf epidermal cells through silicon fertilization.

“…Root applications of 1.7 mM Si reduced the severity of powdery mildew disease (Blumeria graminis f. sp. tritici) on wheat by as much as 80% (Guevel et al, 2007). Guo et al (2007) reported that sodium silicate reduced significantly the severity of post-harvest pink rot of Chinese cantaloupe caused by Trichoth-ecium roseum.…”

Summary The use of silicon (Si) in agriculture has attracted a great deal of interest from researchers because of the numerous benefits of this element to plants. The use of silicon has decreased the intensity of several diseases in crops of great economic importance. In this study, the relationship between silicon nutrition and fungal disease development in plants was reviewed. The current review underlines the agricultural importance of silicon in crops, the potential for controlling fungal plant pathogens by silicon treatment, the different mechanisms of silicon-enhanced resistance, and the inhibitory effects of silicon on plant pathogenic fungi in vitro. By combining the data presented in this paper, a better comprehension of the relationship between silicon treatments, increasing plant resistance, and decreasing severity of fungal diseases could be achieved.

“…This element is absorbed by the plant in the form of monosilicic acid (H 4 SiO 4 ) along with water (mass flow) and accumulates mainly in the maximum perspiration areas as polymerized silicic acid. It promotes the effective control of plant diseases (Amaral et al, 2008;Guével et al, 2007;Pozza et al, 2009) and has been associated with reduced effects of harmful chemical and physical agents (Zhu et al, 2004, Ma & Yamaji, 2006. The benefits of Si can be observed in the growth and production of many grasses such as rice, oats and maize (Wang et al, 2004, Hossain et al, 2007Zanão Júnior et al, 2009) and in some species that are not grass, such as tomatoes and lettuce (Lana et al 2003;Resende et al, 2005).…”

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.
