title: Enhanced Phytochrome Sensitivity and Its Reversal in Amaranthus albus Seeds.
abstract: Seed of Amaranthus alus L. develop an enhanced sensitivity to the farred absorbing form of phytochrome after prolonged imbibition at temperatures >32 degrees C. The enhanced sensitivity developed at 40 degrees C could be reversed by subsequent treatment at 20 degrees C and similarly reestablished by repeating a 40 degrees C treatment. It is concluded that relative sensitivity to the far-red absorbing form of phytochrome may be readily manipulated in seeds of A. albus.
