Calcium treatment for control of postharvest decay in fruits and vegetables

综述了采后钙处理对果蔬腐烂的控制，钙处理的方法及影响因素。钙的防腐机制在于对果蔬采后腐烂的控制，保持细胞壁的结构与功能，增强果实硬度，降低细胞壁降解酶的活性，抑制呼吸，降低乙烯生成量，保持细胞膜的完整性，激活体内的某些氧化酶，诱导合成植保素，作为信号分子，调节细胞功能。

It is reviewed that methods, affect factors and mechanisms of calcium treatment on control of postharvest decay, in fruits and vegetables. A number of lines evidence indicate that calcium treatmens maintain the structure and function of the cell walls, increase the fruit firmness, decrease the activity of the cell wall degration enzymes and ethylene production, maintain the integrity and stability of the membrane, activate some oxidases, induce phytolexin and regulate cell function as a signal mobecular.
