摘要
为提升湖北地区‘鸡尾’葡萄柚品质,以‘鸡尾’葡萄柚为材料,研究设施栽培和露天栽培(CK)模式下果实品质的差异。结果显示:设施栽培下‘鸡尾’葡萄柚果实单果质量、横纵径、果形指数大于CK,果皮硬度在果实发育过程中差异不显著,花后227 d设施栽培和露天栽培果皮硬度出现显著性差异;设施栽培可显著提高果实可溶性固形物含量至10.43%,可滴定酸、Vc含量高于露天栽培;通过GC-MS测定发现,设施栽培可提升果实蔗糖含量至49.63 mg/g;实时荧光定量PCR分析发现设施栽培可能通过上调CsSPS2、CsSUS2和CsSUS4的表达水平来提高果实中蔗糖的含量。结果表明设施栽培可以提高‘鸡尾’葡萄柚的果实品质。
The differences in fruit quality of‘Cocktail’grapefruit between the mode of facility cultivation and open cultivation(CK)were studied to improve the quality of‘Cocktail’grapefruit in Hubei Province.The results showed that the single fruit weight,transverse and longitudinal diameter and fruit shape index of facility cultivation were larger than those of CK.There was no significant difference in peel hardness during fruit development.There was a significant difference in peel hardness between facility cultivation and CK from 227 days after anthesis.Facility cultivation significantly increased the content of soluble solid in fruits to 10.43%.The content of titratable acid and Vc in facility cultivation was higher than that in CK.The results of GC-MS analysis showed that facility cultivation increased the content of sucrose in fruits to 49.63 mg/g.The results of real-time quantitative PCR analysis showed that facility cultivation increased the content of sucrose in fruits by upregulating the expression levels of CsSPS2,CsSUS2 and Cs⁃SUS4.It is indicated that facility cultivation can improve the fruit quality of‘Cocktail’grapefruit.
