The composition of root exudates from two varieties (K 326 and NC 89) of tobacco were identified by GC-MS. Organic acids,amides and esters were the main constituents of the root exudates which differed in their qualitative ...

The release of allelochemicals by aquatic macrophytes can inhibit or benefit other plants. Here we studied allelopathic interactions between syntopic species native to the Neotropical region. First, we quantified the ...

Background and aims: We studied, through exudates employment, the effect of Epichloë (endophytic fungi), both independently and in association with Bromus auleticus (grass), on arbuscular mycorrhizal fungi (AMF) colonization, ...

Motility allows populations of bacteria to rapidly reach and colonize new microniches or microhabitats. The motility ofrhizobia (symbiotic nitrogen-fixing bacteria that nodulate legume roots) is an important factor determining ...

En las semillas de Cedrella fissilis Vell. Se determinó la presencia de una sustancia que lixiviaba al sustrato de germinación. El objetivo de este trabajo fue el estudio de algunas características de la sustancia en cuanto ...

Research with the sunflower crop currently emphasize the use for oil extraction for biodiesel production. The sunflower, because it is a culture of broad adaptation and soil nutrient cycling, has been deployed in systems ...

The effects of soybean genotype and seed coat lignin content on bulk electrical conductivity were investigated. Seeds of nine soybean cultivars were hand harvested at R8 maturation stage in Londrina, PR., Brazil in 1995/96. ...
