“…These results are directly correlated with Si content in fruits (r= 0.97**, 0.96* and 0.99**, respectively), indicating that Si exerts a beneficial effect on fruit firmness (Table 1). The increase of fruit firmness as a result of silicate fertilization was also observed by Stamatakis et al (2003b) and considered as a result of Si deposition in the cell wall (Almeida et al, 2009). Thus, epidermal cells become thicker, with higher degree of silification.…”

This study aimed to investigate the effect of silicon (Si) sources and doses on the physicochemical quality as well as post-harvest conservation of tomato fruits. Treatments were arranged in a 3 x 5 factorial scheme corresponding to sources [calcium silicate, potassium silicate and sodium silicate] and five doses of Si (equivalent to 0, 100, 200, 400 and 800 kg/ha SiO 2 ). Randomized blocks were the experimental design, with four replications. Soluble solids, vitamin C, lycopene, titratable acidity, mature fruit firmness, initial firmness, firmness half-life, time until reaching firmness equivalent to 3.0 x 10 4 N/m 2 and 2.0 x 10 4 N/m 2 and Si content in fruits were evaluated. Soluble solids, vitamin C and lycopene of fruits increased with increasing doses of Si, except for the highest dose. Calcium and sodium silicate provided the highest lycopene concentration in fruits. An increase in initial firmness, number of days until reaching firmness half-life and firmness equivalent to 3.0 and 2.0 x 10 4 N/m 2 were observed along with increasing doses of Si. Tomato fertilization with calcium silicate, potassium silicate and sodium silicate, used as sources of Si, increased the post-harvest conservation as well as the physicochemical quality of tomato.

“…Con respecto a la primera hipótesis, Urrestarazu et al (2016) reportaron, en un estudio histológico realizado en tomate, que la aplicación de sílice aumentó el grosor de la cutícula en hojas y tallos. Además, en tomate, la aplicación de sílice ha reducido la incidencia de enfermedades causadas por patógenos como Ralstonia solanacearum (Diogo y Widra, 2007) y Pythium aphanidermatum (Heine et al, 2007); Almeida et al (2009) probaron la efectividad de la aplicación de silicato de calcio con un fertilizante foliar mineral orgánico para combatir a Frankliniella schultzei.…”

Tomato production stands in first place worldwide. This fruit presents benefits as an antioxidant and is widely used in the Mesoamerican cuisine. In this crop, Fusarium oxysporum causes one of the principal diseases that produce wilting and plant death. In fertilizers use, it is known that application of silica improves resistance to diseases. The objective of this work was to evaluate the effect of fertilization supplemented with silica on resistance of tomato to F. oxysporum. In Peñuela, Veracruz, Mexico, from April to July 2015, doses recommended by the manufacturer, and also one 20% lower and other 20% higher of PSD, Silifertidol Ultra y Fosfosilidol fertilizers were applied to tomato plants. The benefit of silica in plant growth was significantly associated with fertilizer sources and the applied doses. The best result was observed when doses 20% higher than the recommended, were applied, and Cid F1 variety was more susceptible to F. oxysporum. The fertilizer with the best results on the severity and incidence was PSD, and best growth was observed when silica was applied at between 33 and 40%. This investigation reached as a conclusion that the application of fertilizers supplemented with silica, resulted in an improved growth of tomato plants and an increased resistance to F. oxysporum, due to the increase in photosynthetic activity and thickness of the cuticle.

“…Silicon (Si) is not an essential nutrient for plants but it gives positive influence on the growth and development of plants, especially plants exposed to drought (Almeida et al, 2009;Gorecki and Danielski-Busch, 2009;Sacala, 2009;Tale Ahmad and Haddad, 2011;Bocharnikova and Benes, 2011;Son et al, 2011). Some studies indicate that Si application is able to avoid the damage of plant when grown under drought stress condition.…”

A B S T R A C TThe objectives of the study were to determine (1) The level of physiological resistance of oil palm seedlings to drought stress by boron (B) and silicon (Si) application and (2) The mechanism of B and Si actions to induce physiological resistance of oil palm seedlings to drought stress. The B and Si were the elements capably inducing the internal resistance of plant tissues to drought stress, especially through physiological resistance mechanisms. Field trial was arranged in the factorial Randomized Complete Block Design (RCBD) using three blocks as replications. The first factor was six dose of B: 0.00, 0.17, 0.44, 0.87 and 1.31 g plantG 1 . The second factor was five dose of Si: 0.00, 1.15, 2.31, 3.46 and 4.69 g plantG 1 . Observations were done on the Nitrate Reductase Activity (NRA), the content of chlorophyll a, b and total, density, length and width of stomatal aperture, stomatal conductance and transpiration rate, photosynthetic rate and photosynthetic activity per plant, dry weight of plant parts and trunk height and diameter of the oil palm seedlings. The data were analyzed using ANOVA and the means were separated using Duncan's multiple range test at 5% level. Meanwhile, the optimum dose of B and Si were determined using regression analysis. The results showed that B and Si application could induce physiological resistance of oil palm seedlings to drought stress. Mechanism of action of B in inducing physiological resistance of oil palm seedlings to drought stress were by increasing of greenish leaves, width of stomatal aperture and photosynthetic activity per plant while Si application capable to increase of greenish leaves and to decrease the density of lower leaf surface stomatal. The optimal dose of B was 0.33-0.57 g/seedlings and the optimal dose of Si was 2.22 g/seedling in inducing physiological resistance of oil palm seedlings to drought stress.
