Study on the Photosynthetic Characteristics of Bothriochloa ischaemum under Different Water and Nutrient Conditions Ⅲ. Chlorophyll Fluorescence Kinetic Parameters
In order to clarify the photo-physiological characteristics of old world bluestem(Bothriochloa ischaemum L.Keng.) from loess hilly-gully region under different nutrient supplies,the response characteristics to short-term water stress and rehydration treatments of the chlorophyll fluorescence kinetic parameters were determined under potted condition with three nutrient treatments(CK,P and NP).Results showed that the P and NP treatments improved old world bluestem maximum photochemical efficiency(Fv/Fm),activ...
