Comprehensive Evaluation of Chengde Local Peach Fruit Quality Based on Principal Component Analysis
摘要
Abstract
In order to select local Chengde peach varieties with excellent comprehensive fruit quality,fruit quality assessments were conducted on 10 local Chengde peach resources obtained through field surveys.The types and contents of volatile components in ripe fruits of these local Chengde peaches were analyzed using SPME-GC-MS.The comprehensive evaluation of the fruit quality of these 10 local Chengde peach resources was then performed using PCA.There were differences in fruit weight,fruit shape index,soluble sugar,pH,and fruit flavor among the 10 samples of Chengde local peaches,except that no significant differences were observed in soluble solids.Among them,CDMT7 had the highest single fruit weight and a taste that was sour and sweet,while CDMT9 had the highest soluble solids content and a sweet taste,indicating better fruit quality.A total of 80 volatile substances were detected in the 10 samples of Chengde local peaches,with 8 substances found in all samples.CDMT9 had the most types of volatile components detected,51,while CDMT4 had the highest total volatile substance content,2 697.89 μg/g.Esters were the main volatile substances in local peaches from Chengde,with(Z)-hex-2-enyl acetate being the highest content in CDMT1,CDMT3,CDMT6,CDMT7,and CDMT8,while hexyl acetate had the highest content in the other five peaches.The results of the correlation analysis between fruit quality and volatile substances showed that flavor was significantly positively correlated with aldehyde content,while ketone content was significantly negatively correlated with single fruit weight.Based on the principal component analysis of 11 quality indices,four principal component factors were obtained,with a cumulative contribution rate of 80.195%.The results indicated that the quality of the 10 local peaches ranked as CDMT4,CDMT10,CDMT1,CDMT2,CDMT9,CDMT5,CDMT6,CDMT8,CDMT7,and CDMT3.In summary,ketone content,aldehyde content,soluble solids,fruit acidity,and flavor could be used as as comprehensive evaluation indicators for Chengde local peaches.CDMT4,CDMT10,and CDMT9 exhibited excellent comprehensive quality and could serve as excellent parents for peach crossbreeding.关键词
