A greenhouse study was conducted to monitor microbial community dynamics related to contaminant concentration and plant growth during the phytoremediation of pyrene. Soil microbial communities in both bulk and rhizosphere soils were assessed using a polymerase chain reaction--denaturing gradient gel electrophoresis (PCR-DGGE). However, no correlation between pyrene concentration and bacterial c...

of N. coenophialum mycelial proteins was first proposed by Gwinn et al. (1991) using polyclonal antiserum proA reliable, efficient, and accurate detection method for presence duced in rabbits. This technique worked equally well of the endophytic fungus Neotyphodium coenophialum (MorganJones and Gams) Glenn, Bacon, and Hanlin comb. nov. in tall fescue with either seed or plant tissue but seed an...

Wood vinegar, a by-product of wood pyrolysis, is mostly discarded. vinegar has phytotoxic effect and could be potentially used as naturally derived herbicide for weed control. The objective this research was to evaluate the efficacy from pyrolysis apple (Malus × domestica Borkh.) tree branch wastes control weeds. concentrations required inhibit 50% motherwort (Leonurus cardiaca L.), redroot pig...

Exposure to invasive weeds in pasturelands may result significant losses and toxicity forage crops. These species also contain a compound that be toxic as well beneficial depending upon the effect induced. The Ministry of Environment Republic Korea has now recognized Solanum carolinense (Horsenettle)—an weed species—as potential threat crops entire agro-ecosystem. As crop, Festuca arundinacea (...

Soil and sediments of the estuaries and wetlands in Northwest of Persian Gulf are recently polluted with different heavy metals because of municipal and industrial wastewaters. Therefore an urgent soil cleaning up and remediation program is vital in this region. Consequently, this study was initiated to screen two plant species (Festuca arundinacea and Cynodon dactylon) for hyperaccumulation of...

Constructed wetlands have emerged as a viable alternative for secondary treatment of domestic wastewater in areas with landscape limitations, poor soil conditions, and high water tables, which limit installation of full-scale adsorption fields. Existing information on the effects of macrophytes on treatment performance is contradictory and mostly derived from greenhouse mesocosm experiments. Th...

This study investigated the performance of steers grazing rhizomatous birdsfoot trefoil (Lotus corniculatus L.) (RBFT) compared to nonrhizomatous birdsfoot trefoil (BFT) in pure stands or when interseeded with endophyte-free tall fescue (Festuca arundinacea Schreb.; TF). Five forage treatments of RBFT, BFT, TF, RBFT+TF, and BFT+TF (four replicate paddocks per treatment) were continuously stocke...
