Abstract: Photosynthetic responses to light environment can be
useful measurements to determine favorable habitat conditions for the
conservation and cultivation of medicinal species. The nonrectangular
hyperbola model, rectangular hyperbola model, modified rectangular hyperbola
model, exponential model, modified exponential model are used to explore the
best model for describing light-response curves in two Epimedium species. The results
show that the light-response curves of E. wushanense and E. acuminatum were best described by the
modified exponential model, the test MSE and MAE of the modified exponential
model were smaller, and the LSP and Pmax calculated by the modified
exponential model were more accurate than those calculated by other models
in E. wushanense and E. acuminatum. This model may be widely applicable to light-response curves of
other Epimedium species.
