Influence of arbuscular mycorrhizal inoculation and humic acid application on growth and yield of Roselle (Hibiscus sabdariffa L.) and its mycorrhizal colonization index under deficit irrigation
In this study effect of irrigation managements including irrigation after 100 and 200 mm pan evaporation as normal and deficit irrigation respectively was investigated in Roselle plants. Effects of humic acid (including 0 and 4 kg ha-1) and mycorrhizal inoculants (including Glomus versiforme (GV) and Rhizophagus irregularis (RI)) were also studied on growth, yield and mycorrhizal symbiosis inde...

One of the most suitable methods for reducing the effects of copper (Cu) stress is the use of mycorrhizal fungus. This research was conducted to study the effect of Glomus mosseae mycorrhizal fungus on growth and some physiological parameters of pistachio (Pistacia vera) in response to increasing soil Cu concentration. The experiment was carried out as factorial in a completely randomized desig...

One of the most important limiting factors of crop growth in the arid and semi-arid regions is water deficit. Mycorrhizal fungi is one of the most important microorganisms in the rhizosphere. The effects of these fungi apply via changes on some of the characteristics of roots and nutrients uptake in host plants under drought conditions. In order to evaluate the effect of arbuscular mycorrhizal ...
