Vesicular Arbuscular

Spore germination and hyphal growth from spores of the vesicular–arbuscular endophyte Glomus mosseae have been studied under different oxygen and carbon dioxide tensions. Spores failed to germinate at low oxygen tension. This effect was reversible. However, mycelial growth from spores not preincubated in air was irreversibly damaged. The mycelial growth from preincubated spores was affected by oxygen tension. Between 21 and 3% oxygen, growth decreased slightly. Below 3% oxygen it decreased sharply. Again this effect was reversible. A tension of 5% carbon dioxide had no effect on spore germination, but reduced hyphal growth consistently at all oxygen tensions. This effect persisted when spores were subsequently returned to air.

Mycorrhizal Development

The effects of four commonly used commercial formulations of contact fungicides (pentachloronitrobenzene, captan, captafol, and mancozeb) and gypsum on the vesicular–arbuscular mycorrhizal development of Glomus mosseae (Nic. & Gerd.) Gerd. & Trappe in groundnut were studied. Drenching the soil with pentachloronitrobenzene or gypsum at the time of seed sowing significantly inhibited the colonization and sporulation by the fungus; the other fungicides were less toxic. Captan, a widely used fungicide, was least inhibitory on development of the fungus. Pentachloronitrobenzene, gypsum, and captafol treatments significantly reduced the plant biomass.
