中文摘要: 为研究低温条件下不同浓度CaCl2浸泡处理对蓝莓果实采后贮藏品质的影响,该试验以"夏普蓝"蓝莓为材料,贮藏过程中每3 d对蓝莓果实的相关生理指标、抗氧化相关酶活性、类黄酮、总酚及花青素含量进行测定。结果表明:与对照(CK)相比,CaCl2处理能有效降低采后蓝莓果实的腐烂率,减缓失重,抑制果实硬度和可溶性固形物含量的下降,显著提高蓝莓果实过氧化物酶活性,抑制丙二醛含量的上升,延缓类黄酮、总酚和花青素含量的下降。
Abstract:To study the effects of different concentrations of CaCl2 on the post-harvest storage quality of blueberry fruits upon CaCl2 immersion treatment,"Sharp Blue" blueberries were used in this experiment.The relevant physiological indexes;antioxidant-related enzyme activities;and flavonoid,total phenol,and anthocyanin contents of blueberry fruits were determined every three days during storage.Compared with CK,CaCl2treatment was found to significantly reduce the peroxidase (POD)activity,weight loss,total soluble solids(TSS)content,and fruit hardness.It inhibited the formation of malondialdehyde (MDA)and delayed the decrease in the flavonoid,total phenol,and anthocyanin contents.
