| Abstract: | Spores of Lygodium heterodoxum Kunze were stored in dry and fully water-imbibed conditions in darkness at 23–25 C. Spores stored in dry conditions lose viability faster than those stored fully water-imbibed. After 1 year, less than 1% of the spores stored in dry condition germinated, while about 40% of the stored water-imbibed spores still germinated. The spores do not germinate in darkness, but they do germinate under white and far-red light. |
