The influence of Deweile plant nutrients on fruit quality of red-fleshed sweet pomelo was investigated,and the related traits of fruit quality were determined by spraying Deweile in the field. Results:Compared to the control,Deweile plant nutrients increased the weight of single fruit,TSS,TSS/TA,total sugar content,peel brightness,red value of pulp and total phenolic content by 6.7%,1.73%, 8.91,0.93 g/100g,12.78%,18.7% and 31.4% respectively;The contents of total acidity(TA),vitamin C and soluble protein in pulp were reduced by 19.8%,14.2% and 18.2% respectively.The activities of peroxide enzyme(POD),catalase(CAT)and polyphenoloxidase(PPO)in peel were decreased by Deweile plant nutrients.
