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...

The rate of global deposition of Cd, Pb, and Zn has decreased over the past few decades, but heavy metals already in the soil may be mobilized by local and global changes in soil conditions and exert toxic effects on soil microorganisms. We examined in vitro effects of Cd, Pb, and Zn on critical life stages in metal-sensitive ecotypes of arbuscular mycorrhizal (AM) fungi, including spore germin...

Positive effects of dual inoculation with some combinations of arbuscular mycorrhizal fungi (AMF) and bacteria on the growth of micropropagated potato (Solanum tuberosum) transplanted to a peat-based substrate were found in three different cultivation systems — pots, greenhouse or shadowhouse beds. Some inoculation treatments, e.g. with Glomus etunicatum, Glomus fistulosum together with bacteri...

The use of microorganisms to improve the availability of nutrients to plants is of great importance to agriculture. This study aimed to evaluate the effect of triple inoculation of cowpea with arbuscular mycorrhizal fungi (AMF), plant growth-promoting bacteria (PGPB) and rhizobia to maximize biological nitrogen fixation (BNF) and promote plant growth. The experiment was conducted in a greenhous...

influence of arbuscular mycorrhizal fungi (amf) (glomus etunicatum, g. intraradices and glomus versiforme) and external phosphorus supplement (8 and 35 mg p kg-1 soil) on leaf p, zn, cu and fe nutrition of 4-month-old tea(camellia sinensis) was studied in an glass house pot experiment. the highest leaf p concentration (up to 59.43% increase) was found in g. versiforme inoculated seedlings gro...

1. The effects of mutualistic interactions on partner phenotype and fitness can vary with many factors, including the abundance of interacting partners. Partner abundance may determine the relative costs and benefits associated with the interaction. Although arbuscular mycorrhizal fungi (AMF) can strongly influence plant phenotype and community interactions, the effects of AMF abundance on plan...

The seasonal change and host preference of arbuscular mycorrhizal (AM) colonization and community composition of five common plant species Agropyron cristatum, Anemarrhena asphodeloides, Cleistogenes squarrosa, Leymus chinensis, and Stipa grandis in the Inner Mongolia steppe were investigated. The AM root length colonization rates were different among the five plant species and were generally h...
