| 中文摘要: |
| 测定和比较26个甜杨桃和酸杨桃不同种质的果实成熟期果肉可溶性糖、可滴定酸、维生素C、总黄酮、总酚含量的差异，并对杨桃种质果实糖酸含量与抗氧化物质含量进行了相关性分析。结果表明,“大果甜杨桃1号”、“台湾红杨桃种质1”和“闽引新加坡黄杨桃”果实风味好,可作为良好的育种亲本材料；酸杨桃组果肉的可滴定酸、维生素C、总黄酮和总酚含量均高于甜杨桃组,酸杨桃是抗氧化能力较强的种质；相关性分析表明,杨桃果实的可滴定酸含量和维生素C、总黄酮含量显著正相关,而可溶性糖含量与有机酸含量、维C含量、总酚含量、总黄酮含量均无显著相关性。 |
| 英文摘要: |
| The contents of soluble sugar, titratable acid, vitamin C, total flavonoids and total phenols in the flesh of 26 sweet and sour carambola germplasms during fruit ripening were determined and compared, and the correlation between the content of sugar and acid and the content of antioxidant in carambola germplasm was analyzed. The results showed that "Daguo Sweet Carambola No. 1", "Taiwan Red Carambola Germplasm 1" and "Minyin Singapore Yellow Carambola" had good fruit flavor and could be used as good breeding parent materials. The contents of titratable acid, vitamin C, total flavonoids and total phenols in the flesh of sour carambola group were higher than those of sweet carambola group, sour carambola was a germplasm with stronger antioxidant capacity. The correlation analysis showed that the titratable acid content of carambola fruit was positively correlated with the content of vitamin C and total flavonoids, but the content of soluble sugar had no significant correlation with the content of titratable acid, vitamin C, total phenols and total flavonoids. |
