“…The solubility of Si will increase in alkaline conditions (Landré et al, 2018). In this study, the relationship between SiAP and soil pH was consistent with previous studies which reported that soil pH was positively correlated with soil SiAP (Sirisuntornlak et al, 2021). The SiAP of paddy soil has a positive correlation with organic carbon.…”

Silicon (Si) is a beneficial element for rice plants. However, evaluating the Si availability status of paddy soil is rarely done. This study aimed to investigate the Si availability for plant (SiAP), spatial distribution, SiAP correlations with some soil properties and the effect of SiAP status on the rice yield. This study used a survey method to collect paddy soil and water sample. The pot experiment method was used to evaluate paddy plant response to SiAP level. Based on K-means, cluster analysis showed that soil SiAP was categorized low (< 147 mg SiO2 kg-1), moderate (147 – 224 mg SiO2 kg-1) and high (> 224 mg SiO2 kg-1). The SiAP status of the paddy soil area of 26,395 hectares (25%), 61,744 hectares (59%) and 15,952 hectares (15%) was categorized as low, moderate and high, respectively. This present study revealed that the upland area paddy soil has higher SiAP than the lowland area. Total silicon dioxide (SiO2) and clay percentage were negatively correlated with the SiAP in soils. Silicon addition to the paddy soil with SiAP status showed low to high increase in rice yield by 0.2%, 3.9% and 2.7%.

“…The results presented in Tables (4 and 5) revel that increasing application concentration potassium silicate to canola plants significantly in all criteria in both seasons, the spraying concentration of 600 ppm is the best, as the largest values was given to the number of pods per plant (697.38 and 609.44), 1000-seeds weight (4.211 and 4.018 g), seed yield/plant (40.19 and 37.34 g), biological yield (7550 and 7011 kg/feddan),seeds yield (1587.1 and 1432.9 kg/feddan) and oil yield (728.3 and 662.2 kg/feddan) in the first and the second seasons, respectively, This is due to the ability of potassium silicate to raise the efficiency of the plant to withstand inappropriate conditions and thus increase the yield and its components. These results are in the same direction with those obtained by Merwad (2018), Fani et al (2019), Abd Allah et al (2021, Hafez et al (2021) and Sirisuntornlak et al (2021).…”

“…Therefore, the stress-alleviating effects of Si vary with plant species, and generally a significant stress-mitigating role is reported in plants with a higher accumulation of Si in different tissues [ 20 ]. Similarly, Si enhances Al 3+ tolerance in plants by the activation of antioxidant activities [ 21 , 22 ], the formation of the Si-Al 3+ complex [ 23 ], pH increase [ 24 ], the enhancement of organic acid anions, mineral uptake, and the exudation of phenolic compounds [ 25 ], as well as hormonal signaling [ 21 , 26 , 27 , 28 ]. While Si’s involvement in ameliorating Al-induced stress could be due to altering Al transporter activities, conclusive evidence regarding the effect of Si on regulating Al transporters is not available.…”

Silicon- and Boron-Induced Physio-Biochemical Alteration and Organic Acid Regulation Mitigates Aluminum Phytotoxicity in Date Palm Seedlings

The current study aimed to understand the synergistic impacts of silicon (Si; 1.0 mM) and boron (B; 10 µM) application on modulating physio-molecular responses of date palm to mitigate aluminum (Al3+; 2.0 mM) toxicity. Results revealed that compared to sole Si and B treatments, a combined application significantly improved plant growth, biomass, and photosynthetic pigments during Al toxicity. Interestingly, Si and B resulted in significantly higher exudation of organic acid (malic acids, citric acids, and acetic acid) in the plant’s rhizosphere. This is also correlated with the reduced accumulation and translocation of Al in roots (60%) and shoots (56%) in Si and B treatments during Al toxicity compared to in sole Al3+ treatment. The activation of organic acids by combined Si + B application has significantly regulated the ALMT1, ALMT2 and plasma membrane ATPase; PMMA1 and PMMA3 in roots and shoots. Further, the Si-related transporter Lsi2 gene was upregulated by Si + B application under Al toxicity. This was also validated by the higher uptake and translocation of Si in plants. Al-induced oxidative stress was significantly counteracted by exhibiting lower malondialdehyde and superoxide production in Si + B treatments. Experiencing less oxidative stress was evident from upregulation of CAT and Cyt-Cu/Zn SOD expression; hence, enzymatic activities such as polyphenol oxidase, catalase, peroxidase, and ascorbate peroxidase were significantly activated. In the case of endogenous phytohormones, Si + B application demonstrated the downregulation of the abscisic acid (ABA; NCED1 and NCED6) and salicylic acid (SA; PYL4, PYR1) biosynthesis-related genes. Consequently, we also noticed a lower accumulation of ABA and rising SA levels under Al-stress. The current findings illustrate that the synergistic Si + B application could be an effective strategy for date palm growth and productivity against Al stress and could be further extended in field trails in Al-contaminated fields.
