摘要
以7个水蜜桃品种X2-5、新玉、Akatsuki、大玉白凤、白丽、湖景蜜露、玉露为材料,测定各品种果实的大小、单果重、硬度、可溶性固形物含量(TSS)、可滴定酸(TA)、可溶性糖、有机酸、乙烯释放速率、呼吸速率等生理指标,并对其品质进行了研究。结果表明,新品种X2-5果实糖酸比最高、风味好、硬度较大,但从乙烯及呼吸出峰时间看,其可能是个相对不耐贮藏的品种;3个日本引进品种白丽、Akastuki、大玉白凤的可溶性固形物含量及糖酸比都很高,风味较好,其中Akatsuki果实硬度最大,乙烯释放速率最小,白丽的呼吸及乙烯释放速率也较小,而果形最小的大玉白凤果实则出现最高的乙烯和呼吸高峰。
Seven peach cuitivars were used to study the frulit quality, the size, weight, firmness, total soluble sohds, titratable acid, soluble sugar, organic acid, ethylene production rate and respiration rate of fruits were also determined. The results showed that the new cuitivar of ‘X2-5＇ had the highest sugar/acid ratio, better flavor, hard firmness, but the peak of its ethylene and respiration rate came earlier than other cuitivars, indicating that the storage time of this cuitivar was possibly shorter than others. It was also found that three Japanese peaches fruit had higher TSS and sugar/acid ratio, better flavor. Among which,‘ Akatsuki＇ fruit was the hardest, but its ethylene production was the lowest;‘Baili＇ fruit also had lower ethylene and respiration rate. The ‘Dayubaifeng＇ fruit, whose size was the smallest, had highest ethylene and respiration rate.
