比较了葡萄品种巨峰和雷司令二次果与一次果的贮藏和酿酒特性。巨峰葡萄二次果在贮藏期果内还原糖、含酸量、可溶性固形物含量的变化趋势与一次果完全相反；果梗耐拉力、果粒耐压力显著高于一次果，而袋内ＣＯ２浓度、落粒率却显著低于一次果，显示了优良的耐贮性。雷司令二次果的酒中富含必需氨基酸和Ｚｎ，但酒中苹果酸过高。此外，二次果粒小、出汁率低、株产低。
The storage and brewing characteristics of the grape varieties Kyoho and Riesling secondary fruits and primary fruits were compared. Kyoho grape secondary fruit in the storage period of the reducing sugar, acid content, soluble solids content trends and the first fruit exactly the opposite; fruit peduncle resistance to stress, fruit stress was significantly higher than the first fruit, and bag CO2 concentration , Falling rate was significantly lower than a fruit, showing excellent storage stability. Riesling secondary fruit wine is rich in essential amino acids and Zn, but wine is too high malic acid. In addition, the second fruit is small, low juice yield, low yield.
