Coal mining and related industry can increase heavy metals (HMs) concentrations in soil, atmosphere and wheat, thereby posing metal-associated human health risk via food ingestion.  In this study, 58 samples of soil, wheat, and dust were collected from Xuzhou coal mine eastern China, six kinds of HMs Pb, Cd, Cu, Zn, As and Cr were studied for their spatial distribution in wheat, enrichment in d...

a pot experiment was conducted in a completely randomized design with five treatment and five replication, in each replication were 6 plants used. the study of zinc sulphate (znso4) application (20 and 40 ppm) and salicylic acid (sa) application (50 and 150 ppm) was compared to the control (distillated water) on growth and flowering petunia hybrid. for each plant was used 100 cc of solution at ...

this research was carried out on corn in the orzuiyeh region of kerman province over two consecutive seasons (2005-6 to 2007-8). the experiment was done as a split plot with a completely randomized block design and four replications. four levels of consumed water (60%, 80%, 100% water requirement, water use based on regional custom) and three varieties (404sc, 700sc, 704sc) were the main factor...

abstract application of salicylic acid (sa) as a phytohormone has been increased due to its role in plant tolerance to environmental stresses such as drought. the main goal of this experiment was to evaluate the effects of sa on morphological and physiological characteristics of cucumber seedlings under drought stress. a factorial experiment based on completely randomized block design was condu...

BACKGROUND AND AIMS Leaf gas exchange is influenced by stomatal size, density, distribution between the leaf adaxial and abaxial sides, as well as by pore dimensions. This study aims to quantify which of these traits mainly underlie genetic differences in operating stomatal conductance (gs) and addresses possible links between anatomical traits and regulation of pore width. METHODS Stomatal r...

The impact of elevated CO2 (1000μmol/mol) was assessed on the common weed, Arabidopsis thaliana (Landsberg erecta), which is used as a model plant system. Elevated CO2 stimulated relative growth rate (RGR) and leaf area gain of Arabidopsis beginning from the cotyledon stage and continuing through the juvenile stage. This early advantage in growth enabled the plants grown in elevated CO2 to gain...
