Identification of medicinal plants with tolerance to salinity stress has an economical importance in Iran. This study was carried out to evaluate the effects of salinity stress on different Morpho-Physiological traits of Foeniculum vulgare Mill in germination and seedling stage in hydroponic condition. The experiment was conducted as a split plot based on a Randomized Complete Block Design (RCB...
This research was carried out to assessment agro physiological traits of bread wheat affected salinity stress, Nano zinc oxide and arbuscular mycorrhiza (AM) fungi under greenhouse condition via factorial experiment based on randomized complete blocks design with three replications. Experimental factors included salinity stress in three levels [no-salt (S0) or control, salinity 40 (S1), and 80 ...
DOR: 98.1000/2383-1251.1397.5.101.9.1.1578.1610 Extended abstract Introduction: Stevia is a perennial short day plant, belonging to the Asteraceae family. It is also called sugar leaf. Poor germination of this plant serves as a barrier for its planation on a large scale, which contributes to its scarcity and expensivenss as a medicinal herb. In many plants, seed germination is sensitive...
This research was carried on in order to investigate the response of wheat cultivars to salinity tension as factorial experiment and in complete randomized block design in four replications in Islamic Azad University Shoushtar Branch. In this experiment the response of nine wheat cultivars including Chamran, Karchia66, Mahoti, Roshan, Alvand, Kavir, Ghods, Atrak and Tjan at vegetative growth st...
Salinity stress is considered as one of the major factors that reduce plant growth in many regions in the world. Agropyron pectiniforme and Agropyron trichophorum species are perennial grasses species that product valuable forage and grazing material in pasture and rangelands of Iran. The aim of this study was determining effect of salinity stress with NaCl on seed germination traits of Ag. pec...
To investigate the effect of salinity stress on membrane stability index, membrane lipid peroxidation, catalase activity and protein content of Fenugreek (Trigonellafoenum) an experiment with five levels of short-term salinity stress (0, 50, 100, 150 and 200 mM) was carried out at the laboratory of agriculture faculty of Shahid Bahonar University of Kerman, Iran. The treatments were ar...
to study the effect of salinity on physiological and morphological traits of chickpea in 2010 at faculty of agriculture and natural resources, university of tehran with seven chickpea genotypes. two experiments design was rcbd with 3 replications and 5 levels of salinity stress (ctrl, 200, 150, 100, 50 mm) for laboratory experiment on germination indices and greenhouse experiment on physiologic...
abstract soil salinity in huge parts of the world, especially in arid and semi-arid regions, is a factor limiting growth of plant and other organisms. earthworm can be considered as an indicator of soil quality in agroecosystems, because of a positive correlation between earthworm abundance and the productivity of cropped plants. the main objective of this study was to realize the interaction b...
Absolute salinity measurement of seawater has become a key issue in thermodynamic models of the oceans. One of the most direct ways is to measure the seawater refractive index which is related to density and can therefore be related to the absolute salinity. Recent advances in high resolution position sensitive devices enable us to take advantage of small beam deviation measurements using refra...
This paper introduces a potential method for the remote sensing of sea surface salinity (SSS) using the measured propagation delay of low-frequency Loran-C signals transmitted over an all-seawater path between the Sylt station in Germany and an integrated Loran-C/GPS receiver located in Harwich, UK. The overall delay variations in Loran-C surface waves along the path may be explained by changes...
