不同采收期对蓝莓抗氧化物质的影响1）

摘要

In this experiment ,researcher takes blueberry as materials ,studies the influence of the different harvest time on antioxidant compounds of blueberry fructifications .The main results are as follows :During the harvest time‐the 7th day ,the 14th day and the 21st day ,the main active contents of blueberries both anthocyanin and flavonoids significantly increased ,and SOD activity increased ,but POD activity reduced .Therefore ,the main active compound contents and activities of blueberry fruits may be attributed to the different harvest time ,and the change law of Meideng and Beicun is the same .%　　以蓝莓为材料，研究了不同采收期对蓝莓果实中一些重要抗氧化物质积累的影响。主要结果如下：在成熟后的7、14、21d北村和美登2种蓝莓主要活性物质花色素苷和总类黄酮含量均呈上升趋势；超氧化物歧化酶SOD活性呈上升趋势；过氧化物酶POD活性呈下降趋势。试验表明，蓝莓果实中主要活性物质含量及活性与不同采收时期有关，并且主要活性物质的含量及其活性的变化规律在两品种间一致。
