Fig 1. Morphological and physiological changes of cassava in response to waterlogging stress.

Fig 1

(A) Changes of phenotypes and stem base leaves in control and waterlogged seedlings. (B) Determination of photosynthetic indexes and antioxidant enzymes in the leaves and roots under waterlogging stress. The photosynthetic indexes included maximum quantum yield (Fv/Fm) and chlorophyll content (SPAD). The antioxidant enzymes are superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD). Different letters indicate significant differences from the control (P < 0.05). Bars indicate standard error (n = 3).
