study the effects of inoculation with two arbuscular mycorrhizal (am) fungi, gm (glomus mosseae t.h. nicolson & gerd.)gerd & trappe) and gi (glomus intraradices  n.c. schenck & g.s. sm.) on the  herb yield, essential oil (eo) content and nutrient acquisition of basil (ocimum basilicum l.) under drought stress conditions,the experiment conducted with 9 treatments and 4 replications. drought stre...

Abstract This study aims to determine the diversity of arbuscular mycorrhizal fungi in area former gold mine North Sumatra. research was conducted with 5 soil sampling points. The method used began calculating percentage root colonization, spores density and types fungal spores. In addition, physical chemical conditions are also measured. results showed that rate colonization at moderate high a...

In recent years, the use of soil microbial potential including arbuscular mycorrhizal fungi is widely considered to enhance the better growth and nutrition of plants. This research was conducted in order to study the impact of mycorrhizal fungi on the increase of yarrow production and the plant establishment affected by the symbiotic ...

Several species of Phytophthora cause crown and root rot diseases of herbaceous and woody plants. Crown and root rot of pistachio trees cause significant damages in infected orchards. The effect of foliar application with Elite (fosetyl-Al) in 2 and 2.5 g/l was evaluated in greenhouse experiments. The frequency of mortality, fresh and dry weight of roots and shoots, height, intensity of crown r...

a greenhouse experiment was conducted to investigate the effects of mycorrhial fungus (glomus mosseae) on cadmium (cd) toxicity in pepper (capsicum annuum l. cv. zhongjiao 105) plants. half of plants were inoculated with arbuscular mycorrhizal fungi (amf). cd was supplied in the form of cadmium chloride at 0.0, 0.1 and 0.5 mm through irrigation water in the soil. mycorrhizal colonization was hi...

The phenazine-1-carboxamide-producing bacterium Pseudomonas chlororaphis PCL1391 controls tomato foot and root rot caused by Fusarium oxysporum f. sp. radicislycopersici. To test whether root colonization is required for biocontrol, mutants impaired in the known colonization traits motility, prototrophy for amino acids, or production of the site-specific recombinase, Sss/XerC were tested for th...

Not all roots born as first-order branches are the same and this has important consequences for overall function. We hypothesized that, compared with fibrous roots, pioneer roots are built to live longer at the expense of absorptive capacity. We tested this hypothesis by investigating pioneer and fibrous roots in their first 14 d of life in the arbuscular mycorrhizal tree species: Acer negundo,...

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...
