中文摘要: 探究外源硒素对葡萄果实中营养物质和抗氧化物质含量的影响,以巨峰葡萄为试材,叶面喷施不同浓度亚硒酸钠溶液。结果表明:随着硒浓度的增加,葡萄果实中总硒、原花青素、总黄酮、总酚、维生素C、蛋白质、可溶性固形物、总糖含量呈上升趋势,且硒浓度为50 mg/L 时各测量指标达最大值;游离氨基酸含量逐渐下降,可滴定酸含量变化不显著。因此,在生产中可喷施浓度为50 mg/L 的硒溶液,提高葡萄果实中营养物质和抗氧化物质含量。
Abstract:In order to explore the selenium treatment effects on grape antioxidant activity and related substances content.The grape "Ju Feng" as the test material that applicated of different concentrations of sodium selenite.The results showed that with the increase of selenium concentration,the contents of total selenium,procyanidins,total flavonoids,total phenols,vitamin C,protein,soluble solids and total sugar in grape fruits increased,and when the selenium concentration was 50 mg/L,each measurement index reached the maximum value;the content of free amino acids gradually decreased,titratable acid content did not change significantly.Therefore,50 mg/L selenium solution can be sprayed to increase the contents of nutrients and antioxidants in grape fruits.
