Abstract
The spore germination in Thelypteris dentata was studied and the optimum temperature of 25 C was determined by the maximum percentage germination and the highest germination index. The necessity of continuous white light irradiation and reversion of spore germination by subsequent far-red light irradiation indicate the involvement of phytochrome in the control of the process. The dependence of induction of spore germination to the continuous white light low irradiance confirms the phytochrome control through the low fluence response.
