Abstract:

In order to study the difference of strawberry fruit quality formation under substrate cultivation and soil cultivation, and explore its influence law, the contents of sucrose and citric acid and the expression of related genes in different development stages of strawberry were measured. The results showed that contents of sucrose and citric acid in soil culture were higher than those in substrate culture. The difference of sucrose accumulation was mainly reflected in the tip of strawberry fruit, and the difference of citric acid accumulation was in the tip and base of strawberry fruit. FaSPS2 gene was the key gene for the difference of sucrose accumulation between soil culture and substrate culture, which was positively correlated with sucrose accumulation. The expression of FaACO1 and FaACO3 genes were negatively correlated with the accumulation of citric acid. The expression of FaACO1 and FaACO3 in matrix culture were significantly higher than those in soil culture, resulting in the citric acid content of mature strawberry fruit in matrix culture was lower than that in soil culture. Therefore, FaSPS2, FaACO1 and FaACO3 genes played important role in the accumulation of sucrose and citric acid content of Yuexin strawberry. Soil cultivation might be more conducive to the accumulation of sucrose and citric acid content of Yuexin strawberry than substrate cultivation.
