Cassava is widely grown in Inceptisol. As agricultural land, the soil has several problems, i.e., high acidity, easily leached surface layers, unstable aggregates, and slow permeability. Arbuscular mycorrhizal fungi (AMF) form a symbiotic relationship with over 80% of higher plant species. However, effectiveness AMF on cassava not been reported. This study aimed to determine effect inoculants v...

Arbuscular mycorrhizal fungi (AMF) are potential biofertilizers for plants. The succeed and quality of AMF inoculation is related to the type This study aimed find most effective species in Indigofera zollingeriana nurseries. experiment was designed using a completely randomized design with six treatments five replications based on different types single consortium forms. Treatment details incl...

A technique combining PCR and restriction fragment length polymorphism analysis was used to generate specific DNA fragment patterns from spore extracts of arbuscular mycorrhizal fungi. With the universal primers ITS1 and ITS4, DNA fragments were amplified from species of Scutellospora and Gigaspora that were approximately 500 bp long. The apparent lengths of the corresponding fragments from Glo...

Positive effects of dual inoculation with some combinations of arbuscular mycorrhizal fungi (AMF) and bacteria on the growth of micropropagated potato (Solanum tuberosum) transplanted to a peat-based substrate were found in three different cultivation systems — pots, greenhouse or shadowhouse beds. Some inoculation treatments, e.g. with Glomus etunicatum, Glomus fistulosum together with bacteri...

an experiment was conducted, using two year old kinnow plants, budded on rough lemon rootstock, inoculated with different isolates of amf fungi viz., glomus manihotis, gigaspora gigantean and glomus mosseae singly as well as in mixed culture. five primers vans1, ns61,ns21,vaglo,vagiga specific to glomus and gigaspora species were designed and used in a polymerase chain reaction with dna extract...

Analyses of DNA polymorphism and virulence variation were used to evaluate the population structure of Xanthomonas axonopodis pv. manihotis, the pathogen causing cassava bacterial blight in Colombia. We collected strains from the major cassava-growing regions which can be grouped into different edaphoclimatic zones (ECZs) according to environmental conditions, production constraints, and econom...

Restriction fragment length polymorphisms (RFLPs) were used to study the population genetics and temporal dynamics of the cassava bacterial pathogen Xanthomonas axonopodis pv. manihotis. The population dynamics were addressed by comparing samples collected from 1995 to 1999 from six locations, spanning four different edaphoclimatic zones (ECZs). Forty-five different X. axonopodis pv. manihotis ...

Fifty-one strains representing Xanthomonas campestris pv. manihotis and cassavae and different pathovars occurring on plants of the family Euphorbiaceae were characterized by ribotyping with a 16S+23S rRNA probe of Escherichia coli and by restriction fragment length polymorphism analysis with a plasmid probe from X. campestris pv. manihotis. Pathogenicity tests were performed on cassava (Maniho...
