Application to the soil of the insecticide dimethoate had no effect on the growth of soybean colonized by the arbuscular mycorrhizal (AM) fungus Glomus mosseae and by the indigenous AM fungus. The application of the recommended concentration of dimethoate decreased the percentage of colonization of soybean by the indigenous AM population, but no significant effect was observed on the colonizati...

Thielavia gigaspora sp. nov. from herbivore dung is described and illustrated. The new taxon by comparison with previously known species is distinguished by relatively large ascospores (25-38 x 15-21 microm), each showing an apical, protuberant germ pore and a longitudinal dark band. A brief comparison with morphologically related species is given.

Effect of constant and diurnally fluctuating temperatures on arbuscular mycorrhizal (AM) fungi [Glomus etunicatum (GE) and Gigaspora margarita (GM)] infection and the promotion of infected seedling growth through asparagus-AM fungus symbiosis were investigated. 1. At constant temperatures, spore germination rate became maximum at 25 •Ž in GE, and at 25•Ž and 30•Ž in GM. Hyphal growth was enhanc...

Arbuscular mycorrhizal fungi (AMF) are potential biofertilizers for plants. The succeed and quality of AMF inoculation is related to the type This study aimed find most effective species in Indigofera zollingeriana nurseries. experiment was designed using a completely randomized design with six treatments five replications based on different types single consortium forms. Treatment details incl...

The amount of polyphosphate in the intraradical and extraradical hyphae of Gigaspora margarita was estimated from successive extractions with trichloroacetic acid (TCA), EDTA, and phenol-chloroform (PC). In the intraradical hyphae, most of the polyphosphate was present in TCA- and EDTA-soluble (short-chain and long-chain) fractions, whereas most of the polyphosphate in the extraradical hyphae w...
