Vesicular-arbuscular mycorrhizal (M) fungal colonization, growth, and nonstructural carbohydrate status of sour orange (Citrus aurantium L.) seedlings were compared at low- and high-phosphorus (P) supply following inoculation with four Glomus isolates: G. intraradices (Gi, FL208), G. etunicatum (Ge, UT316), G. claroideum (Gc, SC186), and Glomus sp. (G329, FL906). Nonmycorrhizal (NM) seedlings s...

The application of organic fertilizers alone or in combination with bio-fertilizers is important for sustainable agriculture, healthy agricultural production and restoring soil quality. Compost, vermicompost and mycorrhiza amendments could improve soil quality and plant yield. However, little is known about their impact on yield and quality of European borage (Borago officinalis L.). To evaluat...

The most important and sensitive level in the modification of rangelands surrounding the mine is the initial seedling establishment of plants, which often faces failure due to adverse environmental conditions, poor soil nutrients, disturbance of soil different layers and its instability and unstable soil around the mines. New methods of rangeland improvement using biological and non-biological ...

The potential of three arbuscular mycorrhizal fungi (AMF) - Glomus mosseae, G. fasciculatum and G. intraradices- to enhance the production of essential oil and plant growth parameter was investigated in sweet basil (Ocimum basilicum). The AMF inoculation significantly increased plant height, fresh and dry matter yield, oil content and oil yield as compared to non-inoculated basil plants. Essent...

Communities of P-solubilizing bacteria, fungi and arbuscular mycorrhizal fungi, were evaluated in two different ecosystems. Samplings taken from two areas of Atlantic forest, in Paraty-RJ, Brazil, one with a secondary forest and the other with a grass pasture were studied. Four growth media: GL (glucose and yeast extract), GES (glucose, soil extract, KNO3, CaCl2, MgSO4, NaCl, FeEDTA and micronu...

Plants simultaneously interact with multiple organisms which can both positively and negatively affect their growth. Herbivores can reduce plant growth through loss of plant biomass and photosynthetic area, while plant mutualists, such as mycorrhizal fungi, can increase plant growth through uptake of essential nutrients. This is the first study examining whether species-specific associations wi...

Mycorrhizas of vascular plants and mycorrhiza-like associations of liverworts and hornworts are integral parts of terrestrial ecosystems, but have rarely been studied in tropical mountain rain forests. The tropical mountain rain forest area of the Reserva Biológica San Francisco in South Ecuador situated on the eastern slope of the Cordillera El Consuelo is exceptionally rich in tree species, e...

Interactions between herbicides and vesicular-arbuscular mycorrhizal (VAM) fungi are little-known but may differentially affect the development of tolerant and susceptible plants. We conducted this greenhouse study to determine if VAM fungi modify the effects of the herbicide bentazon (3isopropyllH-2 ,1 ,3-benzothid iaz in(4)3H-one 2,2-dioxide) on soybean (Glyc ine max (L.) Merr.) and common co...

in order to investigate the effect of mycorrhizal fungi and phosphorus fertilizer on concentration of leaf nutrients and photosynthetic pigments of bean (phaseolus vulgaris l.) in condition of irrigation with saline water, an experiment was conducted based on completely randomized design with three replications in greenhouse of bahonar university of kerman, iran during 2010. the studied factors...
