乌鲁木齐市引种西梅果实品质比较分析

Comparative Analysis of Fruit Quality of Introduced Prunus domestica Varieties in Urumqi

以新疆乌鲁木齐市引进的5个西梅品种“理查德”“女神”“新梅一号”“法兰西”“红西梅”为试材,采用果实形态、品质检测和比较分析等方法,研究了5个西梅品种16项果实形态和品质指标间的差异,以期为新疆地区西梅引种栽培和推广实践提供参考依据。结果表明:果实蔗糖和甜度值在5个品种间无显著差异(P>0.05),其它指标具有显著差异(P<0.05)。“女神”和“红西梅”具有较高的单果质量;“法兰西”糖酸比和固酸比最高,总酸含量最低;“女神”总酸含量最高;“理查德”氨基酸含量最高。总体来看,“法兰西”果实品质和口感最好,其次为“理查德”和“新梅一号”,“女神”和“红西梅”最低。

Taking ‘Lichade’‘Nyushen’‘Xinmeiyihao’‘Falanxi’‘Hongximei’ fruits of 5 Prunus domestica varieties introduced in Urumqi, Xinjiang as test materials, the differences among 16 fruit morphological and quality indicators of 5 varieties were aralysed by the morphology and quality measurement and comparative analysis, in order to provide reference for introduction, cultivation and promotion plantation of Prunus domestica varieties in Xinjiang.The results showed that there were no significant differences in fruit sucrose content and sweetness value among the five varieties(P>0.05),but other indicators had significant differences(P<0.05).‘Nyushen’and ‘Hongximei’ had higher single fruit weight.‘Falanxi’ had the highest sugar-acid ratio and solids-acid ratio, and the lowest total acid content.‘Nyushen’ had the highest total acid content.‘Lichade’ had the highest amino acid content.In general, ‘Falanxi’ had the best fruit quality and taste, followed by ‘Lichade’ and ‘Xinmeiyihao’,while ‘Nyushen’ and ‘Hongximei’ were the lowest.
