W wyniku zalania wodą zmienia się charakter reakcji związanych...
The effects of hypoxia caused by complete submerging of Mnium undulatum gametophores in water, on their photosynthetic activity and the activity of two antioxidative en zymes: superoxide dismutase (SOD) and catalase (CAT) were investigated. The net photosynthesis was strongly inhibited throughout the experiment, and the strong drop in the maximum quantum yield of the PSII (Fv / Fm) was also observed...
