This study was conducted to evaluate the effect of salinity on concentration of potassium (K), sodium (Na) and chloride (Cl) ions, in sweet lime budded on five citrus rootstocks, including Bakraii (mandarin x sweet lime), Volcameriana, Sour orange, Sweet lime and Mexican lime in a glasshouse, using a randomized completely design with factorial arrangement and four replications. Rootstocks had...
in order to investigate the effects of supplementary calcium chloride and potassium nitrate on plant growth of ammi (carum copticum l.) in different salinity levels and nutrient solutions (ns), an experiment based on randomized complete block design (rcbd) with factorial arrangement was conducted under greenhouse condition in the faculty of agriculture, vali-e-asr university of rafsanjan, durin...
To study the goosegrass (Eleusine indica (L.) Gaertn.) in tall fescue (Festuca arundinacea Schreb.), an experiment in 15-year old turf was conducted during 2006 in Tehran in Sheikh Fazlollah highway using randomized complete block design with 4 replications in 1*1 m2 plots. Treatments were diclofop methyl at 2.5 and 3 Lha-1, fenoxaprop-p-ethyl at 0.8 and 1 Lha-1, clodinafop propargyl at 0.6 and...
kochia (kochia scoparia l. schard) is an annual, halophyte and drought resistant plant that can be irrigated with saline water and a valuable source for forage under drought and saline ecosystem. in order to evaluate the germination characteristic of kochia under different temperatures and salinity stress levels, an experiment was conducted at physiology lab of ferdowsi university of mashhad, i...
The red mangrove (Rhizophora mangle L.) in southern Florida occurs frequently in two distinct growth forms, tall and scrub plants, with the scrub form usually found in coastal inland areas having a higher fluctuation of soil water salinity. In the present study, effects of constant and fluctuating salinities on leaf gas exchange and plant growth of red mangrove seedlings were investigated under...
Limitation of suitable water resources is the most important problem of agriculture in Iran. Considering the condition of shallow and saline groundwater in many parts of Iran, and relative resistance of safflower to salinity, it is necessary to study the contribution of groundwater to water consumption of safflower. In this research, the effects of different water table depths and salinity of g...
In this study, the effects of salinity on the hematological parameters in Mesopotamichthys sharpeyi were investigated within 21 days. One hundred and twenty fish weighing 300-350g were divided randomly to four treatments of urban water and following 3 salinities: 4, 8 and 12 g/lit and blood samples were taken in following days of experiment: 1th, 3th, 7th, 14th and 21th.Hematological parameter...
A doubled haploid (DH) population of barley (Hordeum vulgare L.) generated from salinity tolerant genotype CM72 and salinity sensitive variety Gairdner was studied for salinity stress tolerance at germination, seedling emergence and first leaf full expansion growth stages. Germination study was conducted with deionized water, 150 mM and 300 mM NaCl treatments. Seedling stage salinity tolerance ...

Salinity is one of the most important ecological stresses which have undesirable effects on seed germination. This study was carried out to evaluate the germination of three species of lawn (Poa pratensis, Lolium perenne, Cynodon dactylon) seeds under salinity stress. The effect of different treatments (Gibberellins 50 mgl-1, 2% CaCl2 and hydroprimig in 24 hours) was evaluated on total germinat...
