Due to low organic matter content in most of the cultivated soils of Iran and occurrence of drought stress in plants because of low precipitation, application of sewage sludge compost has been recommended for increasing soil organic matter content and improving soil fertility, increasing crop tolerance to water deficit and improving crop yield. So, in this study, the effects of soil moisture an...
We evaluated drought resistance mechanisms in a drought-tolerant clone (CN5) and a drought-sensitive clone (ST51) of Eucalyptus globulus Labill. based on the responses to drought of some physiological, biophysical and morphological characteristics of container-grown plants, with particular emphasis on root growth and hydraulic properties. Water loss in excess of that supplied to the containers ...
In order to investigate the effect of salinity tension and zinc nano oxide on physiological parameters of Rapeseed and Camelina, a factorial experiment was conducted based on a completely randomized design with three replications in the greenhouse conditions of Department of Biology of Urmia University in 2012-13. The factor of zinc nano oxide was investigated at three levels of zero, 25 and 1...
one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...
In order to investigate genetic diversity and heritability of some morphological traits in five bread wheat (Triticum aestivum L.) cultivars, two separate experiments were conducted based on randomized compeletly blocks design (RCBD) with 3 replications under stress and normal conditions. The results showed that differences between cultivars were significant for the majority of traits in both c...
In order to evaluation of morphological selection criteria for salt tolerance screening in wheat (T. aestivum L.) a factorial experiment based on completely randomized design in 3 replications were conducted under greenhouse condition. Salinity treatments involved 4 levels: S=1.3dSm-1 (control), 5, 10, 15 dSm-1 from calcium chloride and sodium chloride with 10:1 (Na: Ca ratio) and another facto...
Using plants and natural products as medicine is increasing every day. The reason might be a tendency that the societies mostly have toward natural and original products especially natural drugs. Essential oilsare referred to aromatic composition which is found in different parts of a plant and can be used for different remedial and hygienic purposes. One of the plants which have been used a lo...
Ginseng root is used more often than other parts such as leaf stem although extracts from ginseng leaf-stem also contain similar active ingredients with pharmacological functions. Ginseng's leaf-stems are more readily available at a lower cost than its root. This article reviews the pharmacological effects of ginseng leaf-stem on some diseases and adverse effects due to excessive consumption. G...
The pollution caused by the presence of heavy metals in the air, water and soil is one of the world's ecological problems. In this study, the effect of different concentrations of calcium on the absorption and accumulation of Cd and Zn in M. flavida from Brassicacea was studied. For this purpose, concentrations of 100, 400 and 1600 µM calcium and 1, 5 and 10 µM Cd and 10, 20 and 40 ...
