不同水蜜桃品种特征特性识别及品质测定

Identification of characteristic traits and quality evaluation of different honey peach varieties

以种植在奉化区水蜜桃主产区内的6个水蜜桃品种湖景蜜露、新玉、圆梦、锦绣黄桃、玉露、白丽为试材,测定和比较了各品种果实的内外部品质特征特性(果实形状、色泽、果重、果实纵径横径侧径、果肉肉色及肉质、可溶性固形物含量、果核重、果核纵径横径侧径、黏离性等),计算可食率,并对果实裂核特征及原因进行分析。结果表明,不同品种水蜜桃的外观品质、内在品质和可食率存在较大差异,锦绣黄桃和新玉的体积显著大于其他种类,新玉的平均果重最大,达到349.00 g,圆梦可食率最大,达98.20%,白丽和圆梦更加甜美,新玉和白丽香味最浓郁。每种水蜜桃各有优势。

In this study,six honey peach varieties grown in the main peach-producing area of Fenghua District,including Hujingmilu,Xinyu,Yuanmeng,Jinxiu Huangtao,Yulu and Baili,were used as test materials.The internal and external quality characteristics of the fruits of each variety were measured and compared,including fruit shape,color,weight,vertical diameters,horizontal diameters and lateral diameters,flesh color and texture,soluble solids content,kernel weight,kernel vertical diameters,kernel horizontal diameters and kernel lateral diameters,and adhesiveness.The edible rate was calculated,and the characteristics and causes of fruit cracking were analyzed.The results showed that there were significant differences in the appearance quality,internal quality,and edible rate among different honey peach varieties.Jinxiu Huangtao and Xinyu had significantly larger volumes than other varieties.Xinyu had the largest average fruit weight,reaching 349.00 g.Yuanmeng had the highest edible rate,reaching 98.20%.Baili and Yuanmeng was the sweeter,and both Xinyu and Baili had the strongest aroma.Each honey peach variety has its own advantages.
