that ROL is correlated with the physiological attributes of wetland plants. However, correlations between the photosynthetic
rate and ROL varied among plant species. C. flabelliformis showed stronger correlations between photosynthetic rate and ROL,
while the other species exhibited weaker correlations. Therefore, more studies on more wetland plants are needed to reveal
the relationship between ROL and photosynthesis, and to reveal whether ROL is an active physiological process or a passive
process in wetland plants.
