By changing the chemical composition of foliage, the increase in atmospheric CO(2) is fundamentally altering insect herbivory. The responses of folivorous insects to these changes is, however, highly variable. In this review we highlight emerging mechanisms by which increasing CO(2) alters the defense chemistry and signaling of plants. The response of allelochemicals affecting insect performanc...

Abstract Allelopathy is a phenomenon by which plants positively or negatively affect neighboring releasing allelopathic compounds. These allelochemicals are secondary metabolites found in different concentrations shoots, roots, leaves, flowers, and even pollen grains. Allelochemicals have potential as natural bioherbicides for controlling weeds when applied the form of extracts through intercro...

A continuous flow filtration system was designed to identify and quantify the removal mechanisms of Cyanobacteria (Microcystis aeruginosa) by hydroponic biofilters Phalaris arundinacea compared synthetic filters. The units were continuously fed under plug-flow conditions with Microcystis grown in photobioreactors. cells decreased at two rates studied (1.2 ± 0.2 54 ± 3 cm3 minˉ1) results suggest...

Field, greenhouse, and laboratory experiments were conducted to evaluate the impact of soil moisture and phosphorus on allelopathic potential of wheat residues, and to study the effect of wheat extract concentrations on the germination and growth of wild mustard (Sinapis arvrnsis L.). The field experimental design was split-plot with 4 replications. The main factor was three moisture levels inc...
