Effect of simulating transportation vibration stress on the quality of “Saimaiti” apricot fruits

Xinjiang “Saimaiti” apricot was used as experimental material. The effect of the different vibration time and different packages on quality of apricots during the process of simulating transportation was studied. The result showed that respiratory rate of apricots vibration-stressed was increased more obviously than those of the contrast with the extension of vibration time(p <0.05),membrane permeability,ethylene production,total soluble solids and malondialdehyde were increased very significant(p<0.01),chlorophyll of the apricots was decreased more obviously than those of the contrast(p<0.05),VC,organic acid content and firmness of the apricots were decreased very significant(p<0.01). Respiratory rate,malondialdehyde of the apricot fruits with foam-net packages were increased more slowly than those of the no foam-net packages(p<0.05),membrane permeability,ethylene production and total soluble solids were increased very significant(p <0.01). But VC,chlorophyll,organic acid content and firmness of apricots with foam-net packages were kept at a higher level than that of the no foam-net packages(p<0.05). It was suggested that the ethylene production of the apricot fruits with foam-net packages and no foam-net packages were 37.5% and 62.4% higher than ck,the apricot fruits with no foam-net packages was 28.6% higher than that of the with foam-net packages. The bad effect of apricots with foam-net packages was reduced effectively and good quality of apricots under the same condition was maintained during the test of simulating transportation.
