Analysis on Phenotypic and Quality Characters in Fruit of Different Cultivars of Olea europaea in Zhejiang Province
In April 2016,2-year container graftings of Olea europaea'Chenggu No 32','Ezhi No 8'and'Arbequina'were planted in Songyang,Zhejiang province.From August 2020,observations and harvest were carried out on different fruit mature degrees of different cultivars.Determinations were implemented on phenotypes and quality traits of harvested fruits.The result demonstrated that ripening time of'Chenggu No 32'was September 18th,of'Ezhi No 8'and'Arbequina'was October 7th and October 28th,with maturing stage of 28,47 and 68 days.According to the fresh fruit mass and oil content,the best harvest time of the three cultivars was the fifth maturity,the fourth maturity and the fifth maturity.ANOVA on fruit quality showed that there were significant differences among cultivars(P<0.05),and the same in the same cultivar among different maturing stages(P<0.05).Correlation analysis indicated that there was close relation between phenotypic traits and quality traits of cultivars.Principal component analysis on fruit quality traits resulted the top three principal components had the largest characteristic values of 5.88,3.52 and 2.16,with cumulative contribution rate of 88.86%.
