Photoinhibition-Like Damage to the Photosynthetic Apparatus in Plant Leaves Induced by Submergence Treatment in the Dark
Figure 10
The effect of O2 on PSII activity in leaves after dark-submergence treatment.
Efficiency of electron moves beyond QA− (Ψo, A and B) and photochemical efficiency (Fv/Fm, C and D) in leaves of the daylily (A, C) and maize (B, D) during dark-submergence treatment (DST) and with air (DST+Air) or N2 (DST+N2) pumped into the water after 36 h DST. Arrows indicate the time points at which gas was pumped into the water. Means ± SE of eight replicates are presented. Different letters indicate significant differences between the treatments, P<0.05. Differences were analyzed by least significant difference (LSD).
