文摘
- •
High concentrations of CO2 induces the changes of reactive oxygen species and scavenging enzymes.
- •
Hydroxyl radical (
OH) could attack and degrade the cell wall materials of persimmon fruit in vitro.- •
The accumulation of
OH is an important factor that leads to the softening of persimmon fruit.- •
We postulate that
OH may contribute to the postharvest softening of persimmon fruit.
