Abstract

To understand the yield and quality of off-season mulberry fruits, which are cultivated in open fields from autumn, the biological characteristics, bioactive compounds, and antioxidant activities of them were analyzed. Compared with mulberry fruits in normal season, the fruit length, fruit diameter, single fruit weight, fruit yield per meter strip, and the fruits yield per 667 m are significantly lower. The moisture content and juice yield of off-season mulberry fruits are lower than the mulberry fruits in normal season; the pH and soluble solids are higher. The contents of mass fraction of crude protein, total sugar, reducing sugar, total acids, total anthocyanins, and total flavonoids decreased significantly in all batches of off-season mulberry fruits compared with those of normal season. Of off-season mulberry fruits, the contents of glucose, fructose and sucrose, expression, anthocyanin biosynthesis genes, and antioxidant capacity are significantly lower than those in normal season.

摘要

为了解秋季露地栽培的反季节桑椹的产量和品质，对其生物学特性、生物活性成分及抗氧化活性进行了分析。与正常季节的桑椹相比，果实长度、果实直径、单果重、每米条桑果产量和每667平方米桑果产量均显著降低。反季节桑椹的水分含量和出汁率低于正常季节的桑椹；pH值和可溶性固形物含量较高。与正常季节相比，各批次反季节桑椹中粗蛋白、总糖、还原糖、总酸、总花青素和总黄酮的质量分数含量均显著降低。反季节桑椹中葡萄糖、果糖和蔗糖的含量、花青素生物合成基因的表达及抗氧化能力均显著低于正常季节。
