“…These results can be correlated with higher scavenging activity and lower electrolyte leakage in fruits after H 2 S treatment. Our results are in accordance with the findings of Siddiqui et al (2021), Li et al (2017aLi et al ( , 2017b and Ni et al (2016) for litchi, kiwifruit and grape, respectively. This confirms the role of H 2 S in maintaining cell redox homeostasis by alleviating oxidative damage to cellular compounds.…”

“…This higher ROS scavenging activity was confirmed in CUPRAC and DPPH measures of antioxidant activity. A similar effect of H 2 S has been reported in litchi (Deshi et al 2020;Siddiqui et al 2021), banana (Ge et al 2017), kiwifruit (Li et al 2017a(Li et al 2017b, broccoli (Li et al 2017a) and hawthorn fruit (Aghdam et al 2018).…”

Hydrogen sulphide (H 2 S) has emerged as a potential regulator of plant defence against different abiotic stresses. As a climacteric fruit, banana undergoes oxidative stresses shortly after harvest, resulting in faster ripening and senescence. This work examines the effects of vacuum infiltrated H 2 S on ripening inhibition of banana.• Banana fruits were vacuum infiltrated with 1 mM H 2 S. Effects on oxidative stress markers, physiological changes, bioactive compounds and antioxidant potentials were examined during storage at 25 °C and 75-80% RH.• Results indicate that treated fruits were less affected by oxidative stress, as evident by lower accumulation of ROS (superoxide and peroxide ions), elevated phenols content and antioxidant capacity. The ripening inhibitory effects of H 2 S delayed chlorophyll loss and reduced ethylene and CO 2 production. H 2 S infiltration also reduced MDA accumulation and electrolytic leakage, resulting in longer shelf life.• Vacuum infiltration with H 2 S had a protective effect on postharvest banana through overcoming the deleterious effect of ROS and strengthening antioxidant potential. Thus, this method could be promising for enhanced preservation of banana during storage.
