摘　　要：以九年生‘夏黑’葡萄为试材,采用多壁碳纳米管(MWCNTs)对‘夏黑’葡萄叶面以及果实表面进行喷施的方法,分别设置0 mg·L^(-1)(CK)、4 mg·L^(-1)(M1)、8 mg·L^(-1)(M2)、12 mg·L^(-1)(M3)MWCNTs 4个处理,研究了MWCNTs对‘夏黑’葡萄果实品质的影响,筛选出提高‘夏黑’葡萄果实品质的最佳MWCNTs浓度,以期为纳米材料在葡萄生产中的应用提供参考依据。结果表明:MWCNTs显著提高了葡萄果实质量、纵径。处理后第35天,M1、M2、M3处理的果实色泽指数(CIRG)、固酸比、花色苷含量、苯丙氨酸裂解酶(PAL)及查尔酮异构酶(CHI)活性均高于CK,果皮叶绿素含量及可滴定酸含量低于CK。处理后第35天,M2处理的果实色泽指数、可溶性固形物含量、pH、固酸比、花色苷含量、PAL活性、CHI活性均显著高于CK 7.7%、5.9%、3.8%、26.6%、19.7%、25.22%、16.55%;可滴定酸含量、叶绿素含量分别比CK低16%、16%。综合得分表明M2>M1>M3>CK。对‘夏黑’葡萄喷施8 mg·L^(-1)MWCNTs(M2)对其综合品质提升效果最好。Nine-year-old‘Summer Black'grapes were used as the test materials,using the method of spraying the foliage as well as the fruit surface of‘Summer Black'grapes using multi-walled carbon nanotubes(MWCNTs),with four treatments of 0 mg·L^(-1)(CK),4 mg·L^(-1)(M1),8 mg·L^(-1)(M2),and 12 mg·L^(-1)(M3)MWCNTs in four treatments.The effects of MWCNTs on the fruit quality of‘Summer Black'grapes were investigated,and the optimal concentration of MWCNTs to improve the fruit quality of‘Summer Black'grapes was screened,in order to provide reference for the application of nanomaterials in grape production.The results showed that MWCNTs significantly increased grapevine fruit quality and longitudinal diameter.At the 35~(th)day after treatment,fruit color index(CIRG),solid-acid ratio,anthocyanin content,PAL and CHI activity were higher in M1,M2 and M3 treatments than in CK,and pericarp chlorophyll content and titratable acid content were lower than in CK.At the 35~(th)day after treatment,fruit color index,soluble solids content,pH,solid-acid ratio,anthocyanin content,PAL enzyme activity,and CHI enzyme activity were all significantly higher in the M2 treatment than in CK,being 7.7%,5.9%,3.8%,26.6%,19.7%,25.22%,and 16.55%higher,respectively,than in CK.Also titratable acid content and chlorophyll content were lower than CK,16%and 16%lower than CK,respectively.The composite score indicated that M2>M1>M3>CK.Spraying‘Summer Black'grapes with 8 mg·L^(-1)MWCNTs(M2)had the best effect on their overall quality improvement.
