In conclusion, H2S treatment inhibited the development of
chilling injury in banana fruit during both cold storage and ripening
stage. The enhancement of chilling tolerance was associated
with higher ATP and energy status. H2S treatment maintained
higher activities of ATPase, CCO and SDH, which played roles in
enhancing energy status and reducing chilling injury. However,
the complex mechanism of H2S in response to chilling stress in
banana fruit is still unknown. Further studies on the molecular
level are needed for better comprehension.
