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.
苋菜种子在 >32°C 的温度下长时间吸水后，对远红光吸收型的光敏素变得更加敏感。在 40°C 下发育出来的增强敏感性可以通过随后在 20°C 下的处理来逆转，并且通过重复 40°C 的处理同样可以重新建立。因此，可以得出结论，相对光敏素的远红光吸收型的敏感性可以很容易地在苋菜种子中进行操纵。
