摘　　要：以"徐香"猕猴桃果实为试材,研究了3个浓度(1、5、10μL·L^-1)乙烯处理对"徐香"猕猴桃果实冷害相关指标的影响。结果表明,3个浓度乙烯处理维持了猕猴桃果实较高的可溶性固形物含量(SSC),增加了细胞膜透性和丙二醛(MDA)的积累,提高了呼吸速率和乙烯释放速率,促进了果实的冷害指数和冷害率。在本试验3个浓度乙烯处理中,猕猴桃果实冷害发生程度随着乙烯浓度的增大而加重。Effects of three different concentrations of ethylene treatments(1,5,10μL·L^-1)on chilling injury in‘Xuxiang’kiwifruit were investigated.The results showed that,the three concentrations of ethylene treatments maintained the higher SSC content of kiwifruit,increased the cell membrane permeability and MDA accumulation,increased the fruit respiration rate and ethylene release rate,promoted the chilling injury index and chilling injury rate of the fruit.The degree of chilling injury of fruit increased with the increase of ethylene concentration.
