Значение термина phytochrome в knolik
phytochrome - phytochrome
phytochrome - Photoreversiblc, proteinaceous plant pigment, present in very low concentration, energized by red light (wave length 660 nm) to a chemically active form and functioning as an enzyme to initiate reactions that profoundly affect plant growth, e.g. germination, growth of roots, stems, and leaves, flowering, pigment formation, and other displays that are controlled by photoperiod. After activation by red light phytochrome is gradually lost and/or reconverted into the original, inactive form in darkness or, more quickly, in far-red light (wave length 730 nm). Relative amounts of red and far-red light determine amount of phytochrome activated and thus response of plant.
