THE EFFECTS OF WHITE FLUORESCENT LIGHT, FAR-RED LIGHT, DARKNESS, AND MOISTURE ON SPORE GERMINATION OF LYGODIUM-HETERODOXUM (SCHIZAEACEAE)

Spores of Lygodium heterodoxum Kunze were stored in dry and fully wate r-imbibed conditions in darkness at 23-25 C. Spores stored in dry cond itions lose viability faster than those stored fully water-imbibed. Af ter 1 year, less than 1% of the spores stored in dry condition germina ted, while about 40% of the stored water-imbibed spores still germinat ed. The spores do not germinate in darkness, but they do germinate und er white and far-red light.
