The Effects of Arbuscular Mycorrhizal Fungi on Nitrogen Concentration of Berseem Clover in Contaminated Soil with Cadmium
نویسنده
چکیده
The effects of Arbuscular Mycorrhizal fungi on nitrogen concentration of berseem clover were examined in contaminated soil with cadmium. Examined factors included: levels of arbuscular mycorrhizal fungi inoculation (Glomus mosseae) (With and without inoculation), and different levels of soil contamination by cadmium (0, 5, 10, 20, 40 and 80 mg.kg-1). The results showed that the effects of cadmium levels and mycorrhiza fungi were significant on nitrogen concentration (P≤ 0.01). Arbuscular mycorrhizal fungi increased nitrogen concentration in the root and aerial plant 30% and 40.3% respectively. Also cadmium in concentration of 80 mg.kg -1 reduced nitrogen concentration in root and aerial plant 28.3% and 35% respectively.

Influence of Arbuscular Mycorrhizae on Biomass Production and Nitrogen Fixation of Berseem Clover Plants Subjected to Water Stress
Several studies, performed mainly in pots, have shown that arbuscular mycorrhizal symbiosis can mitigate the negative effects of water stress on plant growth. No information is available about the effects of arbuscular mycorrhizal symbiosis on berseem clover growth and nitrogen (N) fixation under conditions of water shortage. A field experiment was conducted in a hilly area of inner Sicily, Ita...

Maintaining the levels of nitrogen in agricultural fields to ensure crop yield performance is challenging due to the complex dynamics of nitrogen transformation in soil. Nitrogen is mainly taken up by plant roots in the form of nitrate, but it is considered as an environmental pollutant that threatens human and animal health. Therefore, it is necessary to use adsorbent compounds to retain nitra...

Effects of the mycorrhizal fungus Glomus intraradices on establishment of subterranean clover (Trifolium subterraneum L.) seedlings in saline conditions were studied in a glasshouse experiment. Growth and nutrient uptake were determined 10, 20 and 30 days after transplanting of mycorrhizal and nonmycorrhizal matched seedlings into soils with five different levels of salinity. Mycorrhizal plants...
