How Do Different Growth Forms of Winter Submerged Macrophytes Species Respond to Underwater Light Quality in a Mesocosm Study?

Underwater light is a key factor that affects the growth of submerged macrophytes. However, the responses of different growth forms of submerged macrophytes to light quality remain unclear. The morphological, physiological, photosynthetic, and stoichiometric responses of erect () and low-canopy () to six different light qualities (white light, R/B = 1:8, 1: 4, 1:1, 4:1, 8:1) were studied by a control experiment.
