Objective: The inoculation of substrates with arbuscular mycorrhizal fungi (AMF) is one of the most important effective strategies applied and one of the aims of sustainable agriculture. Methods: This experiment was conducted to evaluate the effects of AMF inoculation (0, 2.5, and 5 W/W) on morpho-physiological traits such as flower and root dry weight, water-use efficiency and antioxidant capa...

The effects of the phytohormone abscisic acid (ABA) on plant growth and root nodule formation were analyzed in Trifolium repense (white clover) and Lotus japonicus, which form indeterminate and determinate nodules, respectively. In T. repense, although the number of nodules formed after inoculation with Rhizobium leguminosarum bv. trifolii strain 4S (wild type) was slightly affected by exogenou...

Under two monoxenic culture techniques of growing plants (filter paper and silica sand cultures), sugar in root exudate from Meloidogyne incognita-infected tomato increased 133 to 836% over controls. In contrast, amino acids were moderately reduced 52 to 56%. Chromatographic analysis showed that galled root exudate contained three sugars, twelve amino acids, and three organic acids, whereas hea...

in order to evaluate the effects of biofertilizer on soybean (glycine max l.) seed vigor that produced under water deficit condition and related traits, an experiment was conducted in a factorial layout based of complete randomized block design with four replications at the research greenhouse of aboureihan campus- tehran university, iran. experimental treatments were include biofertilizer (see...

The interaction of lesion nematodes, black root rot disease caused by Rhizoctonia fragariae, and root damage caused by feeding of the scarab larva, Maladera castanea, was determined in greenhouse studies. Averaged over all experiments after 12 weeks, root weight was reduced 13% by R. fragariae and 20% by M. castanea. The percentage of the root system affected by root rot was increased by inocul...

with the aim to examine lead tolerance of populus nigra (clone 62/154) in symbiosis with arbuscular mycorrhizal fungi, a greenhouse experiment was carried out in a factorial randomized complete scheme with two factors 1) fungal inoculation in 4 levels (control, inoculation with glomus mosseae, inoculation with g. intraradices and inoculation with g. mosseae + g. intraradices) and 2) lead in 4 l...

We show that the disease tomato foot and root rot caused by the pathogenic fungus Fusarium oxysporum f. sp. radicis-lycopersici can be controlled by inoculation of seeds with cells of the efficient root colonizer Pseudomonas fluorescens WCS365, indicating that strain WCS365 is a biocontrol strain. The mechanism for disease suppression most likely is induced systemic resistance. P. fluorescens s...

ABSTRACT Although the isolated effects of cyanobacteria Anabaena cylindrica and bacteria Azospirillum brasilense are well-known, co-inoculation both can promote other benefits to corn plants’ biological nitrogen fixation growth. The aim was evaluate initial growth chloroplast pigment levels hybrids co-inoculated with A. cylindrica. experiment conducted in greenhouse conditions using completely ...
