Fig. 5. Changes in distribution and content of cell wall calcium in peach fruits. Before storage, Ca2+-precipitates distributed along the middle lamella and close to the plasma
membrane (A). In the MeJA-treated fruits at 5 C for 21 d, the Ca2+-precipitates appeared both in tonoplast and plasma membrane (B), Ca2+-precipitates in cell wall located on
middle lamella. Ca2+-precipitates decreased in plasma membrane and became random in cell wall (C). The arrows indicated the Ca2+-precipitates. The bars in A and C
represented 0.5 lm, and in B represented 1 lm. The content change was showed as D, and the bars in the figure represented standard deviation, and values followed by
different letters were significant difference according to Duncan’s Multiple Range Test at P < 0.05.
