 The study found that silicon SI treatment effectively counteracts the effects of salinity stress on fruit yield and quality by increasing stomatoconductivity, chlorophyll, and decreasing electrolyte leakage in apple plants. The results showed that 0.5 mmC improved root shoot dry weight under salinity condition and the lowest values of membrane permeability were found in 0.5 and 2 mmC treatments. The study hypothesized that C treatment contributed to cell walls involving membrane stabilizing and fortification which increased apple plant tolerance against salinity.
