不同根系功能修复剂对'阳光玫瑰'葡萄果实品质的影响OA

[Objective]The study aims to investigate the influence of diverse root repair agents on the berry quality,aroma components,and their contents of'Shine Muscat'grape,thereby providing theoretical basis and technical support for the application of root repair agents in grape production.[Method]Three-year-old'Shine Muscat'grapes were employed as the experimental materials.Six common root repair agents were administered through drip irrigation at 45 and 55 days after flowering.Berry size,textural properties,and contents of soluble solids,titratable acids,flavonoids,total phenols,and aroma components were determined during berry mature stage.[Result]Soil nutrients in the experimental plots were in an excessive state,with P,K,S,Fe,Mn,and B exceeding the standard.The berry size of'Shine Muscat'grape was increased under the treatment of ZN(Zhongnong Lvkang Microbial Agent),BA(Bio-Nongke algae fungus),and ZZJ(Self-made Bacteria No.3).Different treatments inhibited the accumulation of soluble solids to varying degrees.With the exception of BA,all treatments elevated the titratable acid content and reduced the solid-acid ratio.BA and BH(Bihu+Bihu Seaweed Multivitamin)enhanced the berry firmness.BH and ZZJ increased the flavonoid content of the berry,but did not affect the total phenol content.A total of 43 aroma components were detected in the berry.BH treatment had the greatest number of berry aroma components(36 kinds).Aldehyde substances were the main aroma components in the berry.BA treatment facilitated the accumulation of total volatile aroma substances in the berry,which was higher than the con-trol.[Conclusion]All root repair agents tested can improve berry quality of'Shine Muscat'grape,with BA and BH exhibiting more advantages.
