The watermelon [Citrullus lanatus (Thunb.) Matsum. and Nakai] cultivar Crimson Tide and 7 different gourd genotypes [Cucurbita maxima, C. moschata, Luffa cylindrica, Benincasa hispida, Lagenaria siceraria landraces (Skp and Birecik), and L. siceraria hybrid (FRGold)] with rootstock potential for watermelon were grown under saline conditions (0, 4, 8, 12, and 16 dS m) to investigate the response...

the influence of salinity on the different polyamine fractions (free, conjugated, and bound) was compared in a natrophilic halophyte (beta vulgaris l. cv. ic) and a salt sensitive glycophyte (nicotiana rustica l. cv. basmas). low-level salinity (25 mm nacl) and high salinity (150 and 50 mm nacl for sugar beet and tobacco, respectively) were supplied in hydroponics. under low salinity shoot dry ...

introduction abiotic stresses cause 71% reduction in crop yield around the world, from which 20% is related to salinity stress. the importance of sugarcane increases every day due to greater demand for sugar. since sugarcane has mainly grown in arid and semi-arid regions, salinity is one of the main problems for this crop due to higher evaporation in these areas. salicylic acid (sa) is classifi...

In order to investigate the effects of irrigation water salinity on root traits and absorption of sodium (Na+) and potassium (K+) by wheat cultivars, a factorial experiment, based on completely randomized design with 3 replications, was ‎conducted under greenhouse conditions. The main factor was 7 wheat genotypes ]Ghods, Marvdasht and Bahar (sensitive to salinity) and Arg, Bam, Sistani and Sing...

The interaction between roots and bacterial communities in halophytic species is poorly understood. Here, we used Jerusalem artichoke cultivar Nanyu 1 (NY-1) to characterise root distribution patterns and determine diversity and abundance of bacteria in the rhizosphere soil under variable salinity. Root growth was not inhibited within the salinity range 1.2 to 1.9 g salt/kg, but roots were main...

This experiment was conducted to evaluate the effects of salt stress on some agro-physiological traits in ten varieties of bread (Triticum aestivum L.) and durum (Triticum turgidum L.) wheats in seedling stage. A greenhouse experiment was carried out as a split plot experiment based on a completely randomized design with four replications in hydroponic condition. Different agronomic and physiol...

in order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(triticum aestivum l.), an experiment was carried out at the experimental farm of shiraz university. results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...

Selenium and hydrogen sulfide can alleviate the adverse effects of oxidative stress on plants by improving the oxidative defense system. In order to improve the oxidative defense system of garlic under lead and salinity stress by selenium and hydrogen sulfide, a factorial experiment was carried out using selenium and hydrogen sulfide in a completely randomized design with three replications. Ex...

We compared growth, leaf gas exchange characteristics, water relations, chlorophyll fluorescence, and Na(+) and Cl(-) concentration of two cultivars ('Koroneiki' and 'Picual') of olive (Olea europaea L.) trees in response to high salinity (NaCl 100mM) and elevated CO(2) (eCO(2)) concentration (700microLL(-1)). The cultivar 'Koroneiki' is considered to be more salt sensitive than the relatively ...

Salinity is one of the most important constrain affecting crop growth and productivity. Hence studying salinity at morphological and biochemical point of view has become the basis for understanding salinity and plant interactions. Under stress, plants survive by enhancing the osmolyte accumulation by complex metabolic activities. Present investigation deals with the effect of salinity on growth...
