Abstract
【Objective】 The research studied the effects of putrescine treatment on chilling injury of nectarine fruits during cold storage.【Method】 With the nectarine variety Qinguang 2 as tested material,non-treatment as ck,the effects of chilling injury rate,chilling injury index,endogenous polyamines content,ethylene production,respiration rate,MDA content and the relative membrane permeability were investigated.【Result】 The results showed that nectarine fruits chilling injury stored at 0 ℃ was delayed for 10 days by exogenous putrescine(Put,10 mmoL/L) treatment,the chilling injury rate and chilling injury index were different from ck.The contents of endogenous Put level increased sharply during cold storage and reached a peak value after 45 days,reaching 975.21 nmol/g,spermidine(Spd) and spermine(Spm) level increased continuously,the ethylene production and the respiration rate were decreased,the respiration peak and the ethylene peak were delayed 5 d,the MDA content and the increase in the relative membrane permeability were slowed down.【Conclusion】 The Put treatment has remarkable effect on nectarine chilling injury during cold storage.
