The present study is based on the investigation of a soil hyphomyces, Paecilomyces lilacinus, an opportunistic bio-control agent, in controlling root-knot nematode Meloidogyne javanica on tomato in greenhouse conditions. P. lilacinus, effectively promoted the growth of plants inoculated with M. javanica by suppressing its pathogenesis as root galling by the nematode and egg mass production was ...

in order to study the effects of pgpr application methods on proline and soluble sugars content of yarrow (achillea millefolium l.) under drought stress conditionsan experiment was performed at islamic azad university, yadegar-e-imam khomeini (rah) shahre-rey branch. this experiment was carried out in a split plot arrangement with randomized complete block design in three replications. experime...

On a few occasions, soybeans with broken root tips were included in tests to evaluate resistance to Heterodera glycines. Although females developed on these plants, the numbers tended to be lower than on similarly treated intact roots. To test the possibility that removal of the root meristem affected nematode development, a culture system using pruned soybeans was devised that permitted access...

Long-distance auxin transport was examined in Medicago truncatula and in its supernodulating mutant sunn (super numeric nodules) to investigate the regulation of auxin transport during autoregulation of nodulation (AON). A method was developed to monitor the transport of auxin from the shoot to the root in whole seedlings. Subsequently, the transport was monitored after inoculation of roots wit...

in the present study, the effects of two arbuscular mycorrhizal fungi, glomus mosseae andglomus intraradices, alone and in combination, on the growth parameters, chlorophyll and the root-rot disease of pea (pisum sativum) caused by fusarium solani f.sp. pisi were evaluated under greenhouse conditions. eight different treatments in four replications were designed in randomized blocks. compared w...

biological methods based on using soil beneficial microorganisms’ potentials for creating symbiosis relationship with plants by modifying genetic structure of plants resulting in improving nutritional status and crops quality. this study was conducted in order to investigate the effect of piriformospora indica inoculation on root colonization and uptake and transportation of phosphorus, zinc an...

Two methods of soybean seeds inoculation by Rhizobium japonicum have been compared in a field experiment : i) traditional use of inoculated turf embedding the seeds; ii) use of Cephalobus parvus as bacterial carrier (3 O00 and 300 O00 nematodes per linear meter). There is no difference in yield between the inoculation methods in spite of a greater number of bacterial germs provided by nematode ...

Inoculation of wheat with Azospirillum brasilense, combined with the application of four fungal and bacterium-inhibiting substances to which A. brasilense is resistant in the soil, decreased the rhizosphere population, while it increased wheat root colonization by A. brasilense, even in cases of poor inoculation. The inoculation significantly increased the following wheat plant parameters as we...

Monospecific polyclonal antisera raised against Rhizobium leguminosarum bv. trifolii R39, a bacterium which was isolated originally from red clover nodules, were used to study the colonization of roots of leguminous and nonleguminous plants (Pisum sativum, Lupinus albus, Triticúm aestivum, and Zea mays) after inoculation. Eight weeks after inoculation of soil-grown plants, between 0.1 and 1% of...
