摘要
为摸清油橄榄Olea europaea引入浙江栽植后的表现,以3个主栽品种‘城固32号’O.uropaeain‘Chenggu32’‘鄂植8号’O.uropaeain‘Ezhi 8’和‘豆果’O.uropaeain‘Arbequina’的果实为材料,测定不同成熟度下的果实表型和品质性状,并采用方差分析、相关性分析和主成分分析法确定最佳采收期及果实表型与品质性状的差异性。结果表明,3个品种果实的成熟时间不同,成熟时间从早到晚依次为‘城固32号’(9月18日)、‘鄂植8号’(10月7日)和‘豆果’(10月28日);3个品种果实的成熟期也不同,分别为28 d(‘城固32号’)、47d(‘鄂植8号’)和68d(‘豆果’);根据鲜果质量和含油率确定‘城固32号’‘鄂植8号’和‘豆果’的最佳采收期分别为第5成熟度、第4成熟度和第5成熟度;方差分析结果表明,3个油橄榄品质性状在品种间差异显著(P<0.05),同一品种不同成熟度也存在显著差异(P<0.05);相关性分析分析结果表明,油橄榄果实表型性状间和品质性状间存在显著相关性,通过果实表型性状可以推测果实品质的差异;通过油橄榄果实品质性状主成分分析结果表明,前三个主成分的特征值最大,分别为5.88、3.52和2.16,累积贡献率达到88.86%。本文研究结果有助于通过不同油橄榄品种的表型性状差异来推断果实品质性状的差异性,可为浙江油橄榄品种引种工作提供重要参考。
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%.
