Abstract:
Taking ripe Korla pears as the test materials，the fruits were divided into seven grades based on their single fruit weight，<100 g，100-120 g，120-140 g，140-160 g，160-180 g，180-200 g，and >200 g.Both their external and internal qualities were measured，and a comprehensive evaluation was conducted using the fuzzy comprehensive evaluation equal-weight method and the fuzzy comprehensive evaluation weighted method to explore the relationship between fruit size and quality of Korla pear，in order to provide reference for the grading standards of Korla pears.The results showed that as the fruit size increased，the hardness first decreased and then increased，the total sugar content increased，and the fine and smooth grade worsened.There was no significant difference in the total acid content among different fruit sizes.The fruit shape index，total acid content，and sugar-to-acid ratio did not differ significantly among different fruit sizes.There was a highly significant positive correlation between single fruit weight and total sugar (P<0.01) and a highly significant negative correlation between single fruit weight and fine smoothness，as well as fruit dots (P<0.01).The results of the fuzzy comprehensive evaluation equal-weight method and the fuzzy comprehensive evaluation weighted method were relatively consistent.The fruit sizes with the top three comprehensive scores in both evaluation methods were greater than 140 g.The comprehensive evaluation indicated that fruits with single fruit weight of 140-160 g had the best quality.
