“…Our experimental data show that the addition of P alone increased biomass and grain yield (a significant increase from Si 0 P 0 Si 0 P m Si 0 P h ); but when a combined Si-P fertilization were applied there was no significant increase in biomass and yield except that at Si m P m and Si m P h ( Table 3). This supports the results of previous experiments carried out either in the field Liang et al, 2015;Song et al, 2015) or in pots (Agostinho et al, 2017;Liang et al, 1994;Ma and Takahashi, 1990). Si fertilizer supply increased the stock of bioavailable Si that is crucial for sustainable paddy rice yield production (Klotzbücher et al, 2015).…”

“…This study is how co-fertilization combining Si and phosphorus (P) can affect Si availability and plant uptake, as well as phytolith formation in rice. Si uptake improves the growth of Si-accumulator cereals such as rice (Savant et al, 1997;Ma et al, 2001;Ma et al, 2006;Liang et al, 2015). Si fertilization can enhance rice resistance to biotic and abiotic stresses (e.g., pests, water and heat stress, disease, etc.)…”

Phytoliths are silica bodies formed in living plant tissues. Once deposited in soils through plant debris, they can readily dissolve and then increase the fluxes of silicon (Si) toward plants and/or watersheds. These fluxes enhance Si ecological services in agricultural and marine ecosystems through their impact on plant health and carbon fixation by diatoms, respectively. Fertilization increases crop biomass through the supply of plant nutrients, and thus may enhance Si accumulation in plant biomass. Si and phosphorus (P) fertilization enhance rice crop biomass, but their combined impact on Si accumulation in plants is poorly known. Here, we study the impact of combined Si-P fertilization on the production of phytoliths in rice plants. The combination of the respective supplies of 0.52 g Si kg -1 and 0.20 g P kg −1 generated the largest increase in plant shoot biomass (leaf, flag leaf, stem, and sheath), resulting in a 1.3-fold increase compared the control group. Applying combined Si-P fertilizer did not affect the content of organic carbon (OC) in phytoliths. However, it increased plant available Si in soil, plant phytolith content and its total stock (mg phytolith pot −1 ) in dry plant matter, leading to the increase of the total amount of OC within plants. In addition, P supply increased rice biomass and grain yield. Through these positive effects, combined Si-P fertilization may thus address agronomic (e.g., sustainable ecosystem development) and environmental (e.g., climate change) issues through the increase in crop yield and phytolith production as well as the promotion of Si ecological services and OC accumulation within phytoliths.

“…This fact needs to be clarified to change the rules of the use of fungicides. Taking into account the peculiarities of the organotropic specialization of pathogens of perennial wood diseases and the role of silicon in plant nutrition [11], it was assumed that the reception of root nutrition of plants with silicon containing minerals will increase the resistance of plants to biotic and abiotic stress factors, which will contribute to inhibition of the pathological process and increase the efficiency of the use of chemical agents protection.…”

2 iviv_nnc@ukr.net The purpose. To study spread of chronic illnesses of lumber of grape of fungal etiology on industrial plantings and to develop measures on limitation of injuriousness of causal organisms of diseases in conditions of Northern Black Sea Coast. Methods. Field and laboratory. Influence of diseases of lumber of grape on basic agrobiological indexes is probed: productivity, structure and quality of yield, economic efficiency of growing grape is also calculated. Influence of siliceous mineral (analcime) on spread of diseases and productivity of scrubs is probed. Results. By results of probes it was fixed that diseases of lumber of grape of fungal etiology (esca, eutiposis, black spot) on industrial plantings of Northern Black Sea Coast are spread everywhere. Spread of diseases of lumber of grape and their influence on productivity of scrubs lead to shortage of yield, reduce cost of gross harvest and profitableness of growing technical grades, and also increase net cost of production. It is determined that rooted supplementary feeding of scrubs of grape with analcime enables to suspend pathological process at esca disease, to reduce receptivity of plants to seasonal diseases and as result to augment productivity of scrubs and to increase product quality. It is shown that addition of base fungicides (Kvadris, Antrakol, Merpan, Shavit F and Ridomil Gold) into nutrient medium suppresses development of colonies and spores of causal organisms of eutiposis and black spot. Conclusions. Rooted supplementary feeding of plants with siliceous mineral slows down the pathological process called by esca, and diminishes receptivity of grades of grape to series of seasonal diseases.

Silicon-mediated Improvement in Plant Salinity Tolerance: The Role of Aquaporins

et al. 2017

Silicon (Si) is an abundant and differentially distributed element in soils that is believed to have important biological functions. However, the benefits of Si and its essentiality in plants are controversial due to differences among species in their ability to take up this element. Despite this, there is a consensus that the application of Si improves the water status of plants under abiotic stress conditions. Hence, plants treated with Si are able to maintain a high stomatal conductance and transpiration rate under salt stress, suggesting that a reduction in Na+ uptake occurs due to deposition of Si in the root. In addition, root hydraulic conductivity increases when Si is applied. As a result, a Si-mediated upregulation of aquaporin (PIP) gene expression is observed in relation to increased root hydraulic conductivity and water uptake. Aquaporins of the subclass nodulin 26-like intrinsic proteins are further involved in allowing Si entry into the cell. Therefore, on the basis of available published results and recent developments, we propose a model to explain how Si absorption alleviates stress in plants grown under saline conditions through the conjugated action of different aquaporins.
