Effect of polyamines application on reducing chilling injury incidence in okra pod (Abelmoschus esculentus) stored at low storage temperature

Generally, immature okra pod is perishable and sensitive to chilling when exposed to temperature below 10 °C. Polyamines application has been claimed to be able to cope with low temperature stress due to their polycationic and antioxidant properties. In the present study, the effects of putrescine,...
