Expression analysis of genes related to the AsA synthesis pathway. L-galactose pathway: a-j, D-galacturonic acid pathway: g and h, L-gullosugar pathway: m, inositol pathway: n and o. Duncan’s method was used to detect the differences between different development of fruit at P ≤ 0.05. In the same type of data, there was no significant difference between stages with the same lowercase letter
