摘要
为探究6-苄氨基嘌呤(6-BA)和赤霉素(GA_3)对‘户太八号’葡萄果实品质的影响,以7年生‘户太八号’葡萄为研究材料,在花后第10天和第20天,用不同浓度6-BA和GA_3对葡萄进行两次浸穗处理,以清水处理为对照(CK)。果实成熟后,测定果实的外观品质及内在品质。结果表明,6-BA和GA_3处理均提高了葡萄的果实品质。其中40 mg/L 6-BA处理果实的横径和纵径最大,分别为27.91 mm和28.29 mm。60 mg/L 6-BA处理果实单果重和果穗重最大,分别为11.93 g和644.25 g;可滴定酸含量最低,仅为0.35%。60 mg/L GA_3处理的果实可溶性固形物、可溶性糖含量和总酚含量最高,分别为19.57%、40.92 mg/g和15.13 mg/g。40 mg/L GA_3处理果实单宁含量最高,为7.42 mg/g。60 mg/L GA_3处理果实花色苷含量最高,为3.60 mg/g。通过主成分分析比较得出,60 mg/L 6-BA对‘户太八号’葡萄果实品质的提升效果最佳。
This project aims to investigate the effects of 6-benzylaminopurine(6-BA)and gibberellin(GA 3)on the fruit quality of‘Hutai No.8’grape by taking 7 a‘Hutai No.8’grape as the research material,the grape of which will be treated with different concentrations of 6-BA and GA 3 twice at the 10th day and the 20th day after flowering,and then the water treatment will be used as the control(CK).After fruit ripening,the appearance quality and internal quality of the fruit will be measured.The results showed that both 6-BA and GA 3 treatments improved the fruit quality of grape.The transverse diameter and longitudinal diameter of the fruit treated with 40 mg/L 6-BA were the largest,which were 27.91 mm and 28.29 mm,respectively.The single fruit weight and ear weight of fruit treated with 60 mg/L 6-BA were the largest,which were 11.93 g and 644.25 g,respectively.The titratable acid content was the lowest,only 0.35%.The soluble solids,soluble sugar content and total phenol content of the fruit treated with 60 mg/L GA 3 were the highest,which were 19.57%,40.92 mg/g and 15.13 mg/g,respectively.The tannin content of fruit treated with 40 mg/L GA 3 was the highest,which was 7.42 mg/g.The anthocyanin content of fruit treated with 60 mg/L GA 3 was the highest,which was 3.60 mg/g.Through the comprehensive comparison of principal component analysis, it was concluded that 60 mg/L 6-BA had the best effect on improving the fruit quality of ‘Hutai No.8 ’grape.
