摘要

Silicon (Si) enhances stress tolerance in plants, though its effects can vary across different genotypes. However, most studies on silicon use efficiency have overlooked the genotypic differences in silicon accumulation and its associated benefits. In this study, we screened various wheat genotypes with differing Si accumulation potentials, and selected two contrasting genotypes to understand their physiological responses to different silicon concentrations and the resulting changes in growth and yield in silicon deficient peat soil. Twenty wheat genotypes were screened for silicon accumulation potential by Molybdenum Blue method. Two contrasting wheat genotypes, viz., WW-101 (high Si-accumulator) and SW-2 (low Si-accumulator) were finally selected to investigate the effect of different silicon concentrations on various growth, photosynthetic and yield parameters in silicon deficient peat soil. Significant differences in silicon accumulation were observed among the selected wheat genotypes. Silicon fertilization enhanced plant height, leaf area, biomass, and yield of both wheat genotypes in silicon deficient peat soil. Additionally, silicon supplementation improved the photosynthetic efficiency of both the genotypes by enhancing photosynthetic pigments, increasing water use efficiency, and reducing transpiration rate. The silicon-derived benefits were more pronounced in the ‘WW-101’ genotype compared to ‘SW-2’, indicating genotype-specific differences in silicon uptake and utilization. The observed variation in silicon accumulation among wheat genotypes highlights the critical role of genotype-specific differences in silicon uptake efficiency. Silicon fertilization enhanced the growth and yield of both contrasting genotypes by improving photosynthetic efficiency through increased pigment concentrations and water use efficiency. Notably, the high Si-accumulator genotype WW-101 derived greater benefits from silicon supplementation than SW-2, emphasizing the importance of prioritizing silicon-efficient genotypes to enhance crop productivity in silicon-deficient soils.
