“…It is noteworthy that the stomatal behavior determines the transpiratory requirement of the plants, thus controlling the loss of water in the form of vapor. Although Si is not considered an essential element for plants, studies show that its application to the soil contributes to the growth and increase of productivity [38], as can be observed in this work (Table 3). In saline stress conditions, the plant growth is compromised due to the reduction of the osmotic potential of the soil solution, which reduces the water potential of the plants [39].…”

Aims:The objective of this research was to investigate the effect of calcium silicate on gaseous exchanges and production factors in the sweet pepper, cultivated under conditions of soil salinity induced by potassium fertilization, in protected cultivation. Study Design: The experiment was arranged in a randomized complete block design in a 2 × 5 factorial scheme with five replications. Place and Duration of Study: The experiment was conducted in the sector of Olericultura and Experimentation of the course of Agronomy from October 12, 2018 to February 2019. Methodology: The experiment was arranged in a randomized complete block design in a 2 × 5 factorial scheme (two sources of correction: calcareous and silicon and five increasing rates of KCl equivalent to 150, 300, 450, 600 and 700 kg ha -1 of K 2 O). Ten treatments with five replicates where each experimental unit consisted of a polyethylene pot, with a volume of 19 dm 3 . The electrical conductivity, the determination and quantification of silicon in soil and plant, liquid photosynthesis, stomatal conductance, intercellular CO 2 concentration, transpiration, water use efficiency and instantaneous carboxylation efficiency were analyzed. Dias et al.; JEAI, 40(2): 1-12, 2019; Article no.JEAI.50539 2 Results: With the increase of K 2 O in the soil there was a tendency of reduction in liquid photosynthesis, transpiration, stomatal conductance, intercellular CO 2 concentration, water use efficiency and instantaneous carboxylation efficiency in the presence and absence of calcium silicate. Higher rates of K 2 O (300, 450 and 600 kg ha -1 ) reduced the length and yield of sweet pepper fruits in the presence and absence of calcium silicate. The rate of 150 Kg K 2 O favored the growth of sweet pepper plants in the presence of calcium silicate. Conclusion: It is concluded from the research that the dose of 300 kg ha -1 of K 2 O, in the presence of calcium silicate, provided the best results for the electrical conductivity of 2.76 dS m -1 , silicon content in the soil of 5.70 mg kg -1 , 14% silicon leaf content, improving photosynthetic rates, transpiration, water use efficiency and fruit production. The increase in salinity reduced fruit yield, in the presence and absence of Si. Original Research Article

“…The role of silicon in regulating the water status of plants is of interest, particularly in the context that the initial reduction of the growth of plants under salt stress is due to the osmotic effect of the salt [44]. The researchers found that RWC increased in response to silicon treatments under stress conditions, not only by reducing transpiration rate through the deposition of silicon in leaf and stem epidermis cells, but also by increasing potassium absorbance and translocation to stomatal guard cells, where potassium influences stomatal conductivity [45,46]. It has been suggested that Si can increase plants water content under salinity stress, due to findings that Si reduced the osmotic potential (more negative) and increased turgor pressure of tomato leaves under salt stress [47].…”

Silicon application can improve productivity outcomes for salt stressed plants. Here, we describe how strawberry plants respond to treatments including various combinations of salt stress and nano-silicon dioxide, and assess whether nano-silicon dioxide improves strawberry plant tolerance to salt stress. Strawberry plants were treated with salt (0, 25 or 50 mM NaCl), and the nano-silicon dioxide treatments were applied to the strawberry plants before (0, 50 and 100 mg L−1) or after (0 and 50 mg L−1) flowering. The salt stress treatments reduced plant biomass, chlorophyll content, and leaf relative water content (RWC) as expected. Relative to control (no NaCl) plants the salt treated plants had 10% lower membrane stability index (MSI), 81% greater proline content, and 54% greater cuticular transpiration; as well as increased canopy temperature and changes in the structure of the epicuticular wax layer. The plants treated with nano-silicon dioxide were better able to maintain epicuticular wax structure, chlorophyll content, and carotenoid content and accumulated less proline relative to plants treated only with salt and no nano-silicon dioxide. Analysis of scanning electron microscopic (SEM) images revealed that the salt treatments resulted in changes in epicuticular wax type and thickness, and that the application of nano-silicon dioxide suppressed the adverse effects of salinity on the epicuticular wax layer. Nano-silicon dioxide treated salt stressed plants had increased irregular (smoother) crystal wax deposits in their epicuticular layer. Together these observations indicate that application of nano-silicon dioxide can limit the adverse anatomical and biochemical changes related to salt stress impacts on strawberry plants and that this is, in part, associated with epicuticular wax deposition.

“…Supplementation with silicon exerts a number of beneficial effects as silicon nutrition to the plants improves plant protective mechanisms against diseases, insect attack and unfavourable climatic conditions. Silicon improves plant environment relationship as it can improve plants abilities to withstand in adverse climatic conditions due to the presence of natural anti-stress mechanism that enables higher yields and better-quality end products (Marafon and Endres, 2013). Silicon is an agronomically important fertilizer because it enhances plant tolerance capacity to abiotic and biotic stresses (Liang et al 2005).…”

Alleviation of abiotic and biotic stresses in plants by silicon supplementation

Silicon has been considered as beneficial element for the plants. The supplementation of silicon as nutrient to the plants may play a significant role which includes increase in crop growth and yield, improvement of leaf exposure to light, decreased susceptibility to pathogens and pests and amelioration to abiotic and biotic stresses. The most significant effect of silicon on plants, besides improving their fitness in adverse environmental conditions and increasing agricultural productivity of plants is the restriction of pest attack and prevention of diseases. Unfortunately the significance of silicon nutrition in crop production and mitigation of abiotic and biotic stresses remains unexplored. Hence there is an urgent need to use silicon fertilizers for improvement in crop production. The understanding of the beneficial effects of silicon is important to improve crop productivity as it may enhance plant nutritional value for a growing world population.
