Soil salinity is one of the important and determinant factors in land degradation and desertification. This study was undertaken to investigate salt tolerance in Salsola tomentosa under greenhouse conditions to choose a suitable species for saline conditions. The treatment solutions for salinity tests were different concentrations of NaCl (0, 100, 200, 300, 400, and 500 mM) with three replicate...
Prediction of leaf water potential and relative water content using terahertz radiation spectroscopy
Background & Aim: Increasing economic role of medicinal herbs in recent society and complexity of modern technologies in production (planting and harvesting), transportation, storage, processing, quality evaluation, distribution, marketing and consumption of these products require a thorough understanding of their physical properties. Coefficient of friction of plant on the various surfaces is ...

evaluating of some physiological indices for recognizing water deficit effects, selecting water deficit tolerant oilseed rape genotypes and also evaluation of drought effects on seed and oil yields and its components were the goals of this study. the experiment was conducted as factorial based on a randomized complete blocks design with three replications in east azarbaijan research center for ...
In recent years many models have been proposed for measuring soil water content (θ) based on the permittivity (ε) value. Permittivity is one of the properties used to determine θ in measurements using the electromagnetic method. This method is widely used due to quite substantial differences in values of ε for air, soil, and water, as it allows the θ value to be measured accurately. The perform...
Chickpea (Cicer arietinum L. cv. GPF2) and soybean (Glycine max (L.) Merrill cv. Brag) genotypes were subjected to varying water stress levels of -0.2 to -0.8 MPa to assess their relative sensitivity towards water stress. Soybean seedlings experienced significantly more stress injury (as electrolyte leakage) than chickpea at all stress levels. LD 50 in terms of percent germination, root length,...
This experiment was conducted in 2010 in order to study the effect of drought stress on proline, soluble carbohydrates, relative water content, concentration of potassium and sodium of leaf, electrolytes leakage from leaves and grain yield of spring rapeseed cultivars in Research Greenhouse of Yasouj University, Yasouj, Iran. The experiment was factorial, based on completely randomized design w...
