Korla fragrant pears were treated with CaCl₂ and carboxymethyl chitosan coating (CC), while distilled water was used as control (CK) to clarify the effects of CaCl₂ and CC treatments on the after‐ripening of Korla fragrant pears in cold storage. The results showed that the CaCl₂ and CC treatments could maintain the balance of cell wall components and active oxygen metabolism, reduce membrane lipid peroxidation and damage, and delay and reduce the respiratory and physiological activity intensity, thus delaying the consumption of nutrients in the Korla pear during cold storage and preserving fruit storage quality. Compared with the CK group, both CaCl₂ and CC treatments could effectively delay after‐ripening and reduce the intensity of physiological activity. Furthermore, the combination of CaCl₂ and CC treatment groups yielded better results than the CaCl₂ or CC treatments alone.
