Spectrum of action of seed germination and photoconversion of phytochrome in cotton seedlings

摘要

Spectra of action of seed germination and photoconversion of the phytochrome in etiolized cotton shoots, when irradiating seeds with monochromatic light over the wavelength range of 400-720 nm, were studied. It is shown that the spectra of action of germination and photoconversion are characterized by maximums in red (650 nm) and blue (460-480 nm) areas. A possibility of use of the spectra to reveal pigments, i. e. sensibilizators action on morphogenetic reaction in plants is discussed.
