Following are certain statements are related to the effect of red and far-red light;
a) under a dense canopy much of the red light is absorbed by plant pigments, resulting in transmittance of mostly far-red light
b) Pr (red) has highest photon flux at 680 nm while Pfr (far-red) has highest photon flux at 730nm
c) Pfr far-red light–absorbing form, which is considered to be the physiologically active form of phytochrome
d) R:FR ratio is strongly affected by the presence of a canopy because chlorophyll absorbs far-red but not red light
Which one of the combinations of above statements is incorrect?
