Effects of dog rose and watercress extracts on control of green mould decay and postharvest quality of orange fruits

Abstract

Minimum inhibitory concentration (MIC) and IC₅₀ values and total phenolics of dog rose fruits were 72.5–80 μL mL^− 1, 130 μg mL^− 1 and 5.7 mg GA g^− 1, respectively. The Fashand watercress population and dog rose extracts exhibited mycelia growth inhibition values of 45.08% and 37.12%, respectively. The results of in vivo study indicated that the treatment of inoculated fruits with both methanol extracts especially the watercress plant extract considerably controls the citrus fruits decay (Penicillium digitatum) up to 73%. In conclusion, methanol extracts of dog rose fruits and especially watercress plant had the potential to be used against citrus green mould and even for the improvement of postharvest quality of orange fruits.
