Antioxidative Responses in Banana (Musa Sp.) Cultivars Under Water Stress

Responses of the enzymatic and non-enzymatic antioxidant defence systems as well as oxidative injury in banana ptants (Musasp.) subjected to polyethylene glycol (PEG)-induced water stress were investigated. Micropropagated plantlets of two banana cultivars, '8erangan' and 'Mas'...
