Red light absorption by photosynthetic pigments screens stem tissue of Phaseolus vulgaris L. seedlings to such an extent that the most effective wavelength for the phytochrome induction control of stem growth is approximately 628 nm. Screening is greater in the first internode than in the hypocotyl.
A comparison was made between in-vivo phytochrome difference spectra of light-and dark-grown plant material. Spectral differences were found to be caused, at least to a large extent, by screening by chlorophyll and not by differences in phytochrome. Presence of chlorophyll affects the phytochrome in
