The interaction among Glomus intraradices, Meloidogyne incognita, and cantaloupe was studied at three soil phosphorus (P) levels in a greenhouse. All plants grew poorly in soil not amended with P, regardless of mycorrhizal or nematode status. In soil amended with 50 mug P /g soil, M. incognita suppressed the growth of nonmycorrhizal plants by 84%. In contrast, growth of mycorrhizal plants inocu...

The response of pea (Pisum sativum cv. Avola) to arbuscular micorrizal fungi (AM) species Glomus mosseae and Glomus intraradices and Rhizobium leguminosarum bv. Viciae, strain D293 regarding growth, nodulation and nitrogen fixing activity was studied. Pea plants (Pisum sativum cv. Avola) were grown in a glasshouse until flowering stage (35 days) in 4 kg plastic pots using leached cinnamonic for...

Field experiments were conducted near Weslaco, Texas (Lat. 26° 8' N) between 1999 and 2001 to evaluate the field performance of preand post-mycorrhizal inoculations of tomato and onion (2001 only) transplants. In 1999 ‘Heatmaster’ tomato (Lycopersicon esculentum Mill.) transplants were inoculated with Glomes intraradices (Reforestation Technologies, Salinas, CA) at transplanting; in 2000 ‘Heatm...

This experiment aims at establishing the ability of the endomycorrhizal fungus Glomus intraradices to suppress the plant pathogen Pythium ultimum in cherry tomato. A study published in Canadian Journal of Plant Pathology in 1994 showed that Glomus intraradices suppresses Pythium ultimum in Tagetes patula (french marigold) (St-Arnaud, Fortin, Caron, & Hamel, 1994). Pythium ultimum and other Pyth...

The study evaluated the response of alfalfa (Medicago sativa L) to arbuscular mycorrhizal fungi (AM) species Glomus intraradices and Sinorhizobium meliloti, strain 1021 regarding the dry biomass accumulation, mycorrhizal fungi colonization, nodulation and nitrogen fixation activity. Alfalfa plants were grown in a glasshouse until the flowering stage (58 days), in 4 kg plastic pots using leached...

In agricultural production, carbendazim and other pesticides are used to prevent soybean root rot. However, degrades slowly affects a series of biochemical processes such as soil biological nitrogen fixation nutrient activation in the natural environment. This study mainly investigated effects Rhizophagus intraradices, Acinetobacter calcoaceticus, on biomass, incidence rot, total number bacteri...

Pterocarpus officinalis (Jacq.) is a leguminous forestry tree species endemic to Caribbean swamp forests. In Guadeloupe, smallholder farmers traditionally cultivate flooded taro (Colocasia esculenta) cultures under the canopy of P. officinalis stands. The role of arbuscular mycorrhizal (AM) fungi in the sustainability of this traditional agroforestry system has been suggested but the compositio...

Para determinar la influencia de inoculación rizobacteria Azospirillum brasilense y el hongo micorrízico arbuscular (HMA) Glomus intraradices, así como fertilización química (FQ) (100 kg ha-1 N 60 P2O5) en cártamo (Carthamus tinctorius L.) cvs. ‘Tantoan 91’ ‘Guayalejo’, se establecieron dos experimentos campo localidades humedad restringida región semiárida del norte Tamaulipas, México.
