Excised apical segments of corn root (Zea mays) (5-15 mm from the root cap), some with and some without the root tips (0-5 mm) attached, were washed for varying time periods up to 4 hours in 0.5 mm CaSO(4). After washing, tips were removed from those segments washed with tips attached, and then all segments and tips were analyzed for K(+) content. The root tips (0-5 mm) initially contained abou...
In order to study the effects of seed pre-treatment with potassium nitrate (KNO3), gibberellic acid (GA3) and hydro-priming on growth and yield of two sugarbeet cultivars, an experiment was conducted at Miyandoab Agricultural and Natural Resources Research Station in 2009 growing season. The experimental design was a factorial based on randomized complete blocks design with three replications. ...
Enlarged root systems that extend into the salt affected soil improve water and nutrient capture by plants and can increase plant productivity. In order to examine root system characteristics of four bread wheat cultivars contrasting in salt tolerance (Arg, Ofoq, Tajan and Morvarid) a greenhouse experiment was conducted with applying two salinity levels (0 and 150 mM NaCl) on plants grown in PV...
the ability of composing a coherent and extended piece of writing in second language is considered as a fundamental factor to convey information and ideas of learners through the academic issues. although learners may achieve a perfect academic writing skill through assigning the l2 tasks in content based instruction, but demonstration of their abilities may be related to their ability in l1 es...

The essential component of its root is glycyrrhizin. This study was performed to determine the percentage of the extract and glycyrrhizin content of the roots of Glycyrrhiz glabra grown in different areas of Kerman province and some s...
Investigation of soil properties like Cation Exchange Capacity (CEC) plays important roles in study of environmental reaserches as the spatial and temporal variability of this property have been led to development of indirect methods in estimation of this soil characteristic. Pedotransfer functions (PTFs) provide an alternative by estimating soil parameters from more readily available soil data...
Although both rhizome and root of Panax notoginseng are officially utilized as notoginseng in "Chinese Pharmacopoeia", individual parts of the root were differently used in practice. To provide chemical evidence for the differentiated usage, quantitative comparison and metabolite profiling of different portions derived from the whole root, as well as commercial samples, were carried out, showin...
