Abstract
Effects of calcium on activities ofβ-1,3-glucan synthetase, β-1,3-glucanase, peroxidase(POD) and contentof malondialdehyde(MDA) in apple fruits were investigated by means of storage experiment and solution culture experiment.Starkrimson and Red Fuji were chosen as experimental materials. Results showed that spraying young fruits with calciumsolution decreased the incidence of bitter pit disease, increased the activities of β-1,3-glucan synthetase and peroxidasesignificantly, and reduced the activity ofβ-1,3-glucanase and the content of malondialdehyde. Compared with low calciumcultivation, the activities of β-1,3-glucan synthetase and peroxidase in high calcium solution cultivation were higher andthe activity of β-1,3-glucanase and the content of malondialdehyde were lower. It indicated that metabolic changes ofapple fruits were closely related to calcium nutrition. Decreasing the ability of eliminating the oxygen free radical andaccelerating the decomposition of the cell wall due to calcium deficiency was the main cause of metabolic diseases andquality declining of apple fruits during storage.
