6个欧洲李品种果实品质的综合评价
Comprehensive evaluation of fruit quality of six European plum varieties
摘要
Abstract
Six different varieties of European plum fruit were used as test materials to measure and analyze descriptive phenotype,quantitative phenotype,internal quality of different tissues,antioxidant activity,and other indicators.Through correlation analysis and principal component analysis,key component factors determining quality were identified.The varieties were then sorted based on scores,providing a theoretical basis for the selection and development of European plum varieties.The results indicated significant variations in fruit quality across different varieties(P＜0.05).'President'exhibited the highest fresh single fruit weight,longitudinal diameter,trans-verse diameter,and lateral diameter.There were differences in the distribution of material components in various tissues,with peel show-ing higher levels of soluble sugar,vitamin C,and titratable acid compared to pulp.'France'had the highest soluble sugar content,while'Tacheng Suanmei'had the highest titratable acid content;the varieties'Richard Early'and'Empress'exhibited the highest DPPH free radical scavenging ability in peel and pulp,respectively.'Tacheng Suanmei'has the strongest ability to remove·OH.There is a signifi-cant correlation between vitamin C,flavonoids and fruit free radical scavenging effect.Principal component analysis revealed five common factors with eigenvalues greater than 1.The top three comprehensive scores were achieved by'Empress','France',and'Stanley'.Va-rieties such as'France'and'Empress'with higher peel color and solid content were identified as suitable for fresh consumption.On the other hand,varieties like'Empress'and'Stanley'with the highest hardness scores in key components like single fruit weight,hard-ness,peel and pulp L,and edible rate,that suitable for long-distance transportation and sales.Additionally,varieties like'France','President','Empress',and'Tacheng Suanmei'exhibited higher antioxidant activity,making them ideal candidates for processing into health products with anti-aging properties.关键词
