Physiological response to hydric stress of banana plants cv. `Pineo Gigante' (<i>Musa</i> AAA) regenerated from irradiated buds

Drought has adversely affected agriculture, especially in those crops with high water demand such as Musa. Therefore, finding tolerant plant materials it is required. The aim of this study was to characterize the physiological response of banana plants cv. `Pineo gigante' (Musa AAA), in vitro r...
