摘　　要：滨梅(Prunus maritime Marshall)原产美国,是最耐盐的果树之一。为了探究滨梅果实的特性,以8年生滨梅种质资源FJB植株的成熟果实为材料,从果实表型指标和营养指标两个方面进行分析与评价。结果表明,滨梅成熟果实较小,单果质量约2 g,果面颜色偏红紫或浅蓝,果实可溶性固形物含量为14.84%,总糖为7.86%,可滴定酸为0.79%,糖酸比为10.03,维生素E为0.736 mg/100 g,维生素C为19.38 mg/100 g,总多酚达到了6.97 mg/g,果实花色苷为35.02 mg/100 g,果皮花色苷为260.67 mg/100 g;在钾、钠、铁、镁、钙和锌金属元素中,钾含量最高,其次是钙、钠、镁;酸水解后测得氨基酸总量达0.379 g/100 g,其中,天冬氨酸和谷氨酸两种酸性氨基酸的占比最高,达54.46%。The Prunus maritima Marshall,native to the United States,is one of the most salt-tolerant fruit trees.In order to study the fruit characteristics of beach plum,mature fruits of 8-year-old beach plum germplasm resource FJB were used as materials,and the phenotypic indicators and the nutritional components of the fruit were analyzed and evaluated.The results showed that the mature fruits were diminutive,with a single fruit weight of approximately 2 grams.The fruit surface color ranged from reddish-purple to light blue.The average soluble solid content was about 14.84%,with total sugar of 7.86%,titratable acid of 0.79%,sugar to acid ratio of 10.03.It was rich in vitamin E and vitamin C,at 7.36 mg/kg and 19.38 mg/100 g,respectively.Total polyphenol content reached 6.97 mg/g,fruit anthocyanins content was 35.02 mg/100 g,and peel anthocyanins content reached 260.67 mg/100 g.Among the metal elements of potassium,sodium,iron,magnesium,calcium,and zinc,the content of potassium was the highest,followed by calcium,sodium,and magnesium.After acid hydrolysis,the total amino acid was 0.379 g/100 g,and the proportion of aspartic acid and glutamic acid was the highest,reaching 54.46%.
