“…For example, Si could deposit in the leaf epidermis by spraying silicon fertilizer on the leaf surface, thus improving the resistance of rice to blast disease (Abed-Ashtiani et al, 2012 ). The application of 5.0% calcium silicate on leaves not only increased the activity of polyphenol oxidase in peanut leaves but also made the largest deposition of Si in plants (Packirisamy et al, 2019 ). Therefore, we suggest that Si can not only form deposits directly at the wound site but also induce the accumulation of typical healing structures such as SPP and lignin.…”

Wound healing is a postharvest characteristic of potato tubers through accumulating suberin and lignin, which could reduce decay and water loss during storage. This study aimed to explore the impact and mechanisms of sodium silicate on wound healing of potatoes. After being wounded, “Atlantic” potato tubers were treated with water or 50 mM sodium silicate. The results showed that sodium silicate treatment accelerated the formation of wound healing structures and significantly reduced the weight loss and disease index of tubers. Furthermore, sodium silicate induced the genes expression and enzyme activity of phenylalanine ammonia lyase (PAL), 4-coumarate: coenzyme A ligase (4CL), and cinnamyl alcohol dehydrogenase (CAD) involved in the phenylpropane metabolism, enhancing the synthesis of the main precursors of suberin polyphenolic (SPP) and lignin, such as coniferyl alcohol, sinapyl alcohol, and cinnamyl alcohol. Meanwhile, the gene expression of StPOD and StNOX was activated, and the production of O2− and H2O2 was promoted, which could be used for injury signal transmission and oxidative crosslinking of SPP monomers and lignin precursors. Besides, antimicrobial compounds, total phenolics, and flavonoids were also induced. We suggest that sodium silicate could promote wound healing by inducing the deposition of SPP, lignin, and antimicrobial compounds in potato tubers.

Climate change is anticipated to a vigorous impact on soils and ecosystems due to elevated temperature and changes in precipitation lead to reduce in wheat yield. Thus, afield experiment was performed throughout two seasons 2021 and 2022 at Agricultural Research Station farm, Sakha, Kafr El-Sheikh Governorate, Egypt (30o 56 N latitude and 31o 05 E longitude) to investigate the effect of compost and biochar in the main plots in addition, applied of salicylic acid, potassium silicate and seaweed extract as plant spraying in the subplots on improving some physio-chemical properties of the clay soil, some biochemical constituents and productivity of wheat plants under climate change. The experiment was arranged in a split-plot design with three replicates. Data indicated that applying compost treatment appears to be more successful in reducing pH and bulk density of soil than biochar. Application of biochar treatment reduced electrical conductivity meanwhile, compost increased it. Hydraulic conductivity, total porosity, organic matter content, moisture constants of soil, cation exchange capacity were increased by applying all tested soil amendments in two seasons. All Soil amendments caused a marked improve in soil available nitrogen, phosphorus and potassium content. Meanwhile, compost treatment was the best one in increasing available nitrogen and potassium content. Compost application with all foliar spray had given a first order while foliar application under biochar addition had the second one. Data investigated that potassium silicate treatment increased grain & straw yield, harvest index, yield efficiency, 1000 grain weight, carbohydrates and protein. It is clearly observed that compost with potassium silicate treatment was superior to biochar with all foliar treatments of increasing nitrogen, phosphorus, and potassium concentration of grain and straw yields and its uptakes.

In order to explore the effect of potassium silicate fertilizer on soil nutrient content and silicon content in winter wheat in the open field. The experimental variety is Jimai22. 4 different potassium silicate fertilizer rates were applied as Control (CK, 0kg/hm), Treatment 1 (T1, 45 kg/hm), Treatment 2 (T2, 90kg/hm), Treatment 3 (T3, 135kg/hm). The effects of potassium silicate fertilizer on soil nutrient (soil moisture content, pH, alkali solution nitrogen, available phosphorus, available potassium) and silicon (all silicon, available silicon) content in wheat growth stages were studied. Experimental results show that: The soil moisture content of T1, T2 and T3 was significantly higher than that of CK, among them, there were soil moisture content in each period highest in T2, soil pH is closer to neutral, thereby alleviating the problem of soil acidification; The nutrient content of T2 soil was significantly higher than that of CK; The content of silicon in the soil is proportional to the amount of potassium silicate fertilizer applied, there were silicon content highest in T3. Under the conditions of this experiment, it is recommended that the application rate of potassium silicate fertilizer is 90kg/hm in winter wheat in the open field.
