When gametophytes of Onoclea sensibilis are grown in darkness a filament of a few cells develops which elongates at a constant rate. Low dosages of red light given at the beginning of growth increase the rate of elongation. After about 12 days in darkness, however, gametophytes show a decreased growth rate when given red light.
当节节草的配子体在黑暗中生长时，会发育出一条数细胞组成的细丝，该细丝以恒定的速度伸长。在生长开始时给予低剂量的红光会增加伸长率。然而，在黑暗中生长约 12 天后，给予红光会导致配子体的生长速度降低。
