Abstract: Effects of modified atmosphere packaging and ethylene absorbent treatment on physiology and green preservation in Green Mume were investigated at 25℃。The results indicated that in both modified atmosphere packating and ethylene absorbent treatment,the rate of respiration and production of enthylene slowed down and the contents of chlorphyll and ASA also reduced while fruit firmness was relatively maintained.The treatment of modified atmosphere packaging was better than that of ethylene absorbent.Both treatments improved SOD activity and inhibited the POD activity and the O2-.production rate as well in Green Mume fruits.It suggested that both treatments delayed the degradation of chlorophyll through maintaining the balance of activated oxygen metabolism and inhibiting the rate of respiration and production of enthylene in Green Mume fruits.
