Banana is a tropical crop cultivated in warm places. Chilling stress Egypt making banana crops less productive. Abscisic acid (ABA), key plant hormone, regulates metabolic and physiological processes protects plants from variety of stresses. In vitro growing shoots were pre-treated with ABA at four concentrations (0, 25, 50, 100 mM) chilled 5°C for 24 h, followed by six-day recovery period 25°C...

Pawpaw (Asimina triloba) fruit stored longer than 4 weeks at 4 8C fail to ripen normally and may develop internal discoloration, indicative of chilling injury (CI). To determine if loss of antioxidant protection in the fruit tissue during cold storage could be the cause of these problems, the levels of total, reduced, and oxidized glutathione and ascorbate and the key enzymes glutathione reduct...
