Experiments were performed in a laboratory chamber to investigate the influence of alfalfa plants on the fate and transport of trichloroethylene (TCE) fed at 200 μl/l concentration in the entering ground water. Concentrations of TCE in the aqueous and gas phases were regularly monitored in the chamber. Evapotranspirational fluxes of TCE were also reported from the soil to the headspace of the c...

objectives this study examined 125i concentrations in the edible parts of five types of plants from different locations on farms with a similar climate. near zahedan, iran. background radioiodine 125i is an environmental contaminant that humans may consume in edible plants. the characteristics of 125i in plants are poorly understood. materials and methods the experiments used a mini-column appr...

in vitro propagated and conventional runner propagated plantlets of strawberry (fragaria×ananassa duch) cv. ‘festival’ were transferred to the field and the size of crown for plants derived from both sources of planting material were compared. four sizes of the crown, i.e., < 0.5, 0.5-0.8, 0.8-1, and > 1 cm were taken from both sources of planting material. the results obtained flashed that veg...

as a diagnostic probe for P. syringae pv. tomato. In a survey of 75 plant-associated bacteria, pTPR1 hybridized exclusively to those strains that produced coronatine. The detection limit for this probe, which was labeled with the Chemiprobe nonradioactive reporter system, was approximately 4 x 103 CFU of lesion bacteria. During the 1989 growing season, a total of 258 leaf and fruit lesions from...

The importance of trees in a challenging urban environment ABSTRACT Our cities are a challenging environment for plants due to urban specific environmental stresses like urban heat island effects altering the radiative regime. Ecosystem service provision by urban trees qualifies the uptake of urban greening as an engineering solution to climate change. Further interdisciplinary research and wid...
