In dessert ecosystem, evaluation of range species tolerance to salinity stress is more and more appreciable for saline rangelands reclamation and forage production. The principal goal of this investigation is the effects salinity stress on production and tillering of Aeluropus lagopoides, Aeluropus littoralis, Puccinellia distans. The experiment was carried out In a completely randomized design...
plant growth is often limited by low levels of soil micronutrients such as copper (cu), especially in calcareous salt-affected soils of arid and semiarid regions. the aim of this work was to investigate individual and combined effects of salinity and cu on growth, leaf relative water content (lrwc), cell membrane permeability, lipid peroxidation, and total phenolic content (tpc) of rosemary...
The effects of salinity and supplied calcium chloride on growth and leaf ions concentration of tomato (Lycopersicon esculentum L.) were investigated in Gorgan, Iran. A factorial experiment was conducted based on RCBD with four NaCl levels (0, 50, 100, and 150 mM) and four CaCl2 levels (0, 100, 200 and 300 mg L-1). Data of growth, yield and leaf’s Ca, K, and Na content were subjected to analyze ...
the effects of salinity and supplied calcium chloride on growth and leaf ions concentration of tomato (lycopersicon esculentum l.) were investigated in gorgan, iran. a factorial experiment was conducted based on rcbd with four nacl levels (0, 50, 100, and 150 mm) and four cacl2 levels (0, 100, 200 and 300 mg l-1). data of growth, yield and leaf’s ca, k, and na content were subjected to analyze ...
To study the effects of soil Cu and salinity levels on uptake of micronutrients by shoots and roots of pistachio seedlings, a factorial experiment was carried out as completely randomized design with three replications in greenhouse of College of Agriculture, Vali-e-Asr University of Rafsanjan, Iran, in May 2008. Treatments consisted of five salinity levels (0, 800, 1600, 2400 and 3200 mg NaCl ...
Questions: 1. Do pine seedlings in estuarine environments display discrete or continuous ranges of physiological tolerance to flooding and salinity? 2. What is the tolerance of Pinus taeda and P. serotina to low salinity and varying hydrologic conditions? 3. Are the assumptions for ecological equilibrium met for modeling plant community migration in response to sea-level rise? Location: Albemar...
Soil water, salinity and nitrogen content are three major factors affecting crop production in arid and semi-arid areas. This study was performed in two years of 2009 and 2010 in a semi-arid area in order to investigate the effects of irrigation water quantity (as main plot), quality (saline water, as sub-plot), nitrogen fertilizer (as sub-sub plot) and their interactions on growth and yiel...
in order to study the effects of irrigation water salinity and leaching fraction on soil chemical characteristic, grain yield, yield components and sodium and potassium contents in leaves of safflower, an experiment was coducted in a split plot design with four replications in 2009 at roudasht, isfahan. treatments included three irrigation water salinities of q1=3.35, q2=8.77 and q3=11.21 ds/m ...
Abstract Dorema ammoniacum is a medicinal plant, with plenty of chemical constituents, which has been used extensively in curing diseases. To study the salt tolerance of Dorema ammoniacum, its seedlings were put under different salinity treatments under hydroponic conditions. Dorema ammoniacum seeds were transferred to cold (4-5 °C) pretreatment for germination for 27 days. The germinated seed...
Iris (Iris spp.) is one of the major ornamental and pharmaceutical plant species from Iridaceae family. The aim of this study was investigation the effect of mycorrhizal fungi on some morphophysilogical charachteristics of three genotypes of Iris germanica under salt stress. Experiment was conducted on a factorial and completely randomized design (CRD) with three replications. Treatments of thi...
