changes in the symplast/apoplast relation, and modi fi cation of the
cell wall structure and dynamics (Valero & Serrano, 2010). Although
the mechanism involved in citrus sof tening is still unclear, the re-
sults reported herein could be attributed to higher turgor pressure
in treated lemons, since lower weight losses and reduced softening
are shown.
With respect to TSS and TA , the levels of TSS at harvest signifi -
cantly decreased during storage for all fruit without signi fi cant
differences between control fruit and treated with wax or
wa x þ imazalil, although the reduction was lower in those lemon
treated with wax þ EOs (Table 2). On the contrary, initial TA levels
