Air pollution is one of the most important problems threatening organic life and ecosystem throughout world. Among components air pollution, ones are heavy metals that can be toxic carcinogenic even at low concentrations nutrient elements harmful when high concentrations. Thus, monitoring metal in very plants widely used as biomonitor for this purpose. However, which organs more suitable determ...

Recent studies have shown that, in some species, xylem hydraulic conductivity (K(h)) increases with increasing cation concentration of xylem sap. Evidence indicates that K(h) increases as a result of the de-swelling of pit membrane pectins caused by cation neutralization of polygalacturonanes. We tested whether this ionic effect partly compensates for the embolism-induced loss of stem hydraulic...

Field experiment was carried out at Ornamental Nursery, Department of Horticulture, Khyber Pakhtunkhwa (KP) Agricultural University Peshawar, during 2009 to study “the response of plane tree cuttings to different planting dates”. Three types of cuttings (hardwood cuttings, semi-hardwood cuttings, Softwood cuttings) and three dates (6 January, 21 January and 5 February) were studied. The experim...

With this study, Cataldag province extending at the provincial borders of Balıkesir and Bursa, field studies were performed 11 different study areas per three weeks using pitfall traps window with old hollow seven original forest tree species (Alnus glutinosa, Carpinus betulus, Platanus orientalis, Fagus Quercus petreae, Q. cerris, cerris x infectoria) in between April November months during 20...

The aim of this study was to evaluate the effect raw (RawBC) and iron (Fe)-modified biochar (FeBC) derived from Platanus orientalis Linn branches on plant growth, enzyme activity, bioavailability uptake As, Cd, Pb by rice in a paddy soil with continuously flooded (CF) or alternately wet dry (AWD) irrigation pot experiment. Application RawBC (3%, w/w) significantly increased pH, while FeBC decre...

Podosphaera (Sphaerotheca) euphorbiae on Euphorbia epithymoides (= E. polychroma, cushion spurge) is reported for the first time in North America. Neoerysiphe (Erysiphe) galeopsidis on Lamium amplexicaule (henbit), Blumeria (Erysiphe) graminis on Festuca idahoenis (Idaho fescue), Taphrina johansonii on Populus tremuloides (trembling aspen), and Taphrina occidentalis on Alnus rubra (red alder) a...
