Effects of Exogenous Melatonin Treatment on Storage Quality of Strawberry Fruits with Shelf Life at Normal Temperature
To explore the effects of melatonin(MT)treatment on the storage quality of different straw-berry varieties during normal temperature shelf life after harvest.Two varieties of strawberry,Benihoppe and Akihime,were treated with melatonin concentrations of 300,500,700 μmol·L-1,and treated with dis-tilled water as the control.The morphology,physiological and biochemical indexes of strawberry fruits during shelf life at normal temperature were determined.The results showed that compared with the control,melatonin treatment reduced the water loss rate,pulp decay rate and decay index of strawberry fruits of Benihoppe and Akihime,delayed the decline of fruit hardness,soluble solid,titrable acid and Vc contents,inhibited the rise of malondialdehyde(MDA)content,and increased the contents of total phenols,flavonoids and anthocyanins.In conclusion,melatonin treatment can significantly improve the storage resistance and storage quality of strawberries under normal temperature storage.In addition,when the melatonin concentration was 500 μmol·L-1 and 700 μmol·L-1,the treatment of Benihoppe strawberry and Akihime strawberry could effectively delay the deterioration of fruit,and the preservation effect was better.
