- W2262642386 abstract "The more important results of the foregoing investigations may be stated as follows:-- 1. Under ordinary conditions of temperature and inorganic nourishment, moss and liverwort spores are unable to germinate in the dark. Spores when subjected to the more strongly refrangible rays of the spectrum only behave the same as in darkness. 2. Organic nourishment in the form of either peptone or grape sugar will call forth the germination of moss spores in complete darkness. Moss protonemata are able to attain a considerable size in the dark, by a saprophytic nourishment, although the vigor of growth is considerably below the normal. 3. Under ordinary conditions of temperature and inorganic nourishment, fern spores are unable to germinate in the dark.A higher temperature, however, will furnish conditions for the germination in complete darkness. 4. The spores of Equisetum germinate apparently as well in darkness as in light and at the ordinary room temperature of 19-21⚬C. The experiments for this work were conducted during 1896-7 at the Botanical Institute, Leipzig, under the direction of Herr Geheimrat Professor Dr. Pfeifer, to whom thanks are due for many valuable suggestions." @default.
