This could be attributed to a delay in the progression
of several aspects of fruit ripening by calcium, by inhibition
of starch hydrolysis and formation of sugars that could be mainly
due to high amounts of calcium deposition in the fruit cell wall of
these T2 and T4 treated fruit. In the cell walls, components such
as pectic substances (pectic acid), calmodulin (a calcium binding
cell wall protein) and hemicellulose polysaccharides are the most
likely binding sites for calcium
