摘要: 为研究促成栽培下的不同蓝莓品种在10 ℃贮藏条件下的耐贮性,以天津蓟州区的8个蓝莓品种为材料,分析了9项指标的变化。结果显示,贮藏至8 d时,好果率均在80%以上,贮藏至14 d时,仅‘布里吉塔’和‘蓝金’的好果率达到了80%;‘北陆’和‘布里吉塔’的果实硬度较高,‘布里吉塔’的失重率最低,‘蓝丰’可溶性固形物一直较高,‘莱克西’的含糖量和花青素及总酚含量一直最高,‘蓝金’Vc含量一直最高;贮藏至14 d时果实可溶性固形物和含糖量的下降率为10%~28%,Vc、类黄酮、花青素下降率为19.2%~71.0%。隶属函数综合分析显示:‘布里吉塔’贮藏性最好,之后依次为‘蓝金’‘莱克西’‘北陆’‘瑞卡’‘蓝丰’‘奥尼尔’‘伯克利’。各指标的相关性分析显示,果实硬度是决定蓝莓果实耐贮性的关键指标。

Abstract: In order to study the storability of different blueberry varieties under cultivation at 10 ℃, the changes of 9 indexes of fruit were analyzed using 8 varieties in Jizhou district of Tianjin. The results showed that the good fruit rate was above 80% after storage for 8 days, and‘Brigitta’and‘Bluegold’reached 80% when stored for 14 days. The fruit hardness of‘Northland’and ‘Brigitta’remained higher, the weightloss rate of ‘Brigitta’was the lowest, the soluble solids of ‘Bluecrop’ was always higher, and the sugar content, anthocyanin and total phenol content of ‘Legacy’ were the highest.The Vccontent of ‘Bluegold’ was the highest all the time.When the blueberry was stored up to 14 days, the decrease rate of soluble solids and sugar content of the varieties ranged from 10% to 28% .The decline rates of Vc, flavonoids, anthocyanin in fruit were 19.22% to 71.0%.The comprehensive analysis of the membership function showed that‘Brigitta’had the best storability, followed by‘Bluegold’ ‘Legacy’ ‘Northland’ ‘Reka’‘Bluecrop’‘O Neal’and‘Berkeley’. The correlation analysis of each index showed that the firmness index was the key index to determine the storability of blueberry.
