MeJA treatment enhanced
the content of ester and carboxyl group and decreased the
content of carboxylate group in cell wall of fruits stored at 5 C
(Fig. 4B). It was clear that MeJA treatment affected not only the
content of pectic polysaccharides, hemicellulose and cellulose,
but also the state of carboxylic groups when fruits were stored at
5 C (Fig. 4B).
