摘　　要：本研究以金红一年生被迫休眠期枝条为试材,评价摇动浸提时间、抽真空处理及煮后冷却时间对电解质渗出率的影响,为苹果抗寒性评价鉴定提供参考。研究结果表明:枝条摇动浸提18~22 h,电解质渗出率趋于稳定;抽真空处理对电解质渗出率的影响不显著;煮后冷却时间为2~3 h,电解质渗出率趋于一致。因此,苹果一年生休眠期枝条电解质渗出率,在150 r/min、22℃条件下摇动浸提20 h,煮后冷却2~3 h测定较为适宜。In this study,Jinhong annual branches in forced dormancy period were used as test materials to evaluatethe effects of shaking extraction time,vacuum treatment and cooling time after cooking on electrolyte leakage rate,so as to provide reference for the evaluation and identification of cold resistance of apples.The results showed thatthe electrolyte leakage rate tended to be stable when the branches were shaken for 18~22 h.The effect of vacuumtreatment on the electrolyte leakage rate is not significant.After boiling,the cooling time was 2~3 h,and the elec-trolyte leakage rate tended to be consistent.Therefore,it is more appropriate to determine the electrolyte leakagerate of apple shoots in annual dormant period under the condition of 150 r/min and 22℃by shaking and extractingfor 20 h,and then cooling for 2~3 h after boiling.
