The effect of potash biofertilizer and chemical fertilizer was studied on quantitative and qualitative traits of periwinkle in a factorial experiment based on a Randomized Complete Design with three replications, 48 experimental units, and two factors: (1) different methods of potash bio-fertilizer application at four levels of control (B0), seed inoculation (B1), root inoculation (B2) and seed...

systemic induction of peroxidase and polyphenoloxidase in tomato roots and stem followed by application of split root system method was investigated. root system of tomato seedling in the sixth growth stage were divided in two equal sections after washing and replanted in two adjacent pots and then inoculated with nematode and fungus as fallowing treatments. the second treatment was inoculation...

drought, high and low tempratures are the most important abiotic stresses in chickpea cultivation. improving plant root characteristics (root length and root volume) is one of the ways to increase drought tolerance in chickpea. mycorrhizal symbiosis increases drought resistance of host plants through different mechanisms. to study the effects of water stress and mycorrhizal fungi inoculation on...

In order to study of the effect of seed inoculation with PGPR on nitrogen and phosphorus use efficiency of spring wheat in different levels of nitrogen and phosphorus fertilizers, an experimental was conducted at the Research Farm of Mohageh Ardabili University, Ardabil, Iran during 2012 year. The combination of nitrogen fertilizer in three levels (0, 40 and 80 kg N/ha as urea) and phosphorus f...

Autoregulation of symbiotic root nodulation in soybean seedlings (Glycine max L. Merrill cv Pride 216) was studied following double inoculation of primary roots with Bradyrhizobium japonicum 110. When the second inoculation was given 10 or 17 hours after the first, the nodulation in the first-inoculated region of the root was suppressed. The effect was eliminated if B. japonicum 110 containing ...

Wild-type soybean (Glycine max [L] Merr. cv Bragg) and a nitrate-tolerant supernodulating mutant (nts382) were grown in split root systems to investigate the involvement of the autoregulation response and the effect of timing of inoculation on nodule suppression. In Bragg, nodulation of the root portion receiving the delayed inoculation was suppressed nearly 100% by a 7-day prior inoculation of...

The rapid juvenile growth of eastern cottonwood (Populus deltoides Bartr. ex Marsh.) makes it a desirable hardwood species for revegetation of disturbed sites. In addition, revegetation may be facilitated by improved root growth in response to endomycorrhizal colonization. An experiment was conducted to identify the effect of inoculation with a mix of three Glomus spp. isolates on the root grow...
