Spore Germination. In the 1980’s, spore germination was examined in a wide range of mycorrhizal fungi. Methods included germinating spores on agar, on membranes above soil or soil solutions or in soils, and in root organ cultures. We study spore germination either for qualitative taxonomic analysis (to observe mode of germination) or to ...Significance. Dormant bacterial spores can survive long periods of time, withstanding extreme conditions, but can rapidly resume a vegetative life form once nutrients become accessible. The key event of this revival process is termed germination, the earliest phase, lasting only for a few minutes, during which cellular awakening is established.Spores were stored protected from light in sterile distilled water at 4°C and washed every 2 weeks to prevent germination. Spores were quantitated microscopically with a Petroff-Hausser counting chamber, and spore preparations were checked before use for the absence of germinating spores.spore definition: 1. a reproductive cell produced by some plants and simple organisms such as ferns and mushrooms 2….
