in order to study the effects of single and combined applications of biofertilazer and organic fertilizers on quantitative and qualitative characteristics of anisum (pimpinella anisum), an experiment was conducted based on a randomized complete block design with three replications and fifteen treatments at research station, faculty of agriculture, ferdowsi university of mashhad, iran, in 2011 y...

Plant growth is highly dependent on bacteria, saprophytic, and mycorrhizal fungi which facilitate the cycling and mobilization of nutrients. Over 95% of the sulfur (S) in soil is present in an organic form. Sulfate-esters and sulfonates, the major forms of organo-S in soils, arise through deposition of biological material and are transformed through subsequent humification. Fungi and bacteria r...

Abstract In order to study the effect of different soil amended and biological fertilizers on accumulation nitrogen phosphorous in wheat grain some physiological morphological characteristics wheat, this experiment was performed as a split factorial arranged randomized block design with 32 treatment three replication for 2 years. The treatments included mycorrhiza inoculation main factor (witho...

Forest ecosystems are the regions where there is least human interference and therefore we see luxury of plant growth. Sithkhandi forest one interfered forests present near Bhokar region Nanded district in Maharashtra. Arbuscular mycorrhizal fungi (AM fungi) develops symbiotic relation with most land plants. This association very common terrestrial ecosystem throughout world. The objective curr...

The study of fungal-bacterial interactions in soils is not only interesting from a basic point of view but has also yielded findings of societal and economical relevance, such as in the application of biological controls of plant diseases. This study evaluated the effect of Tsukamurella paurometabola C 924, a bacterium with nematocidal action isolated from banana rhizosphere, as single inoculan...

The effect of root exudates from non-mycorrhizal and mycorrhizal cucumber (Cucumis sativus L.) plants colonized by one of three arbuscular mycorrhizal fungi (Gigaspora rosea Nicolson & Schenck, Glomus intraradices Smith & Schenck, or Glomus mosseae (Nicolson & Gerdemann) Gerd. & Trappe) on hyphal growth of Gi. rosea and G. intraradices in axenic culture and on root colonization by G. mosseae in...

The production of hydrolytic enzymes from external mycelia associated with roots and colonized soybean roots (Glycine max L.) inoculated with different arbuscular-mycorrhizal (AM) fungi of the genus GLOMUS:, and the possible relationship between these activities and the capacity of the AM fungi to colonize plant roots was studied. There were differences in root colonization and plant growth bet...

Arbuscular mycorrhizal (AM) fungi are obligate biotrophs that acquire carbon (C) solely from host plants. AM fungi can proliferate hyphae in, and acquire nitrogen (N) from, organic matter. Although they can transfer some of that N to plants, we tested the hypothesis that organic matter is an important N source for the AM fungi themselves. We grew pairs of plants with and without the AM fungus G...

Arbuscular mycorrhizal fungi are the most widespread root fungal symbionts, forming associations with the vast majority of plant species. Ectomycorrhizal development alters gene expression in plant symbionts. In this work we examined the effect of arbuscular mycorrhizal fungi spores on the growth and development of Brassica and on the expression of BnMT2 in winter rape. In a pot experiment, rap...

in order to investigate the response of mycorrhizal fungi to different kinds of fungicides and phytohormone balance in soybean, the present study was carried out during 2008-2009 at research site of azad university of karaj branch as factorial based on randomized complete block design with two factors and four replications. treatments were all combination of arbuscular mycorrhizal fungi species...
