Table_2_Biological characteristics, bioactive compounds, and antioxidant activities of off-season mulberry fruit.docx

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 m2 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.

为探究秋季露地栽培的反季节桑葚的产量与品质，本研究对其生物学特性、生物活性成分及抗氧化活性进行了分析。与当季桑葚相比，反季节桑葚的果长、果径、单果重、米条挂果量及667㎡产量均显著降低。反季节桑葚的含水率与出汁率均低于当季桑葚，而pH值与可溶性固形物含量则更高。各批次反季节桑葚的粗蛋白质、总糖、还原糖、总酸、总花青素及总黄酮的质量分数均较当季桑葚显著下降。反季节桑葚的葡萄糖、果糖、蔗糖含量，花青素生物合成相关基因的表达水平及抗氧化能力均显著低于当季桑葚。
