Abstract:

In this study, Nanfeng mandarin—"Yang Xiao-2, 6"was used to investigate the effects of three different natural antistalings (Chitosan, Salicylic acid and Methyl jasmonate) treatment on the post-harvest physiology and storage life under cold storage. The results showed that the fruit treated with chitosan of 1.5% had the best effect in retention. The time of being decayed of fruits was the latest. The fruit treated with salicylic acid of 0.1g/L had the lowest fluctuation in respiration and SSC. Its total soluble protein reached the biggest climactic values. We found that the effect of 10μmoL/LMeJA concentration was the best of all in SSC, total sugar, titratable acid, Vc, total soluble protein etc.
