Effect of Growth Regulators on Quality and Shelf Life of 'Summer Black' Grapes

Triennial‘Summer Black'grape was used in this study to discuss the effects of various growth regulators,such as Qibao,GA3,CPPU and Baoguo 909,on the appearance,quality and shelf life of the grapes.Among the regulators,Qibao and Baoguo 909 showed better results in weight gains of clusters and berries,and significant increases in soluble solids and sugar-acid ratio,as well as the diameter of stems and berries.However,considering the cost,Qibao was better than Baoguo 909.
