Cell wall composition of calcium-treated apples inoculated with Botrytis cinerea

摘要: Abstract The role of calcium in maintaining cell wall integrity was investigated cortical tissue apple fruit. Carbohydrate, phenolic, protein and mineral element composition were determined walls high- low-calcium content fruit inoculated with Botrytis cinerea . Cell fungal-infected showed a decrease non-cellulosic polysaccharides containing galacturonosyl, rhamnosyl, arabinosyl, xylosyl galactosyl moieties increases cellulose, wall-bound phenolics, elements. In infected high-calcium fruit, the compositional changes generally smaller compared those observed treatment. results this investigation indicate that effect reducing decay is associated structure by delaying and/or modifying chemical composition.
