Salinity stress as a major agricultural limiting factor may influence the chemical composition and bioactivity of Rosmarinus officinallis L. essential oils and leaf extracts. The application of salicylic acid (SA) hormone may alleviate salinity stress by modifying the chemical composition, gene expression and bioactivity of plant secondary metabolites. In this study, SA was applied to enhance s...

Rocky intertidal organisms are facing pronounced fluctuations in environmental conditions even at small spatial and temporal scales. This heterogeneous habitat is a proper model system to investigate effects of physical parameters and their interactions on physiological performances of marine organisms. In the intertidal zone (especially in tidal pools), the temperature and salinity usually inc...

Due to worldwide increasing of salinity, the identification of genes conferring tolerance to plants is important. The aim of this study was to investigate salinity effects on the expression of three genes-related to proteins and aquaporin in grape (Vitis vinifera L.). Based on screening study on 18 grape genotypes, H6 and Gharashani that showed lower decrease in water potential, leaf area, leaf...

theeffect of salt stress on the pysiological and biochemical responses of the seedlings of eight eucalyptus species viz. e. kingsmillii, e. tetragona, e. salubris, e. occidentali, e. microtheca, e. camaldulensis, e. globules and e. sargentii was analyzed. four month-old seedlings grown in greenhouse were watered by five levels of salt solution (0, 50, 100, 150 and 200 mm of nacl) in five replic...

The genetics of’ salinity tolerance in rice was studied by visual scoring in parents F1 F2 and backcross generations of six crosses. Segregation analysis indicated partial dominance for salinity tolerance. Estimation of genetic parameters under epistatic model indicated the importance of additive effects in the inheritance of salinity tolerance. Highly significant additive type of gene action i...

Salinity is a major limiting factor for the proliferation of plants and inhibits central metabolic activities such as photosynthesis. The halotolerant green alga Dunaliella can adapt to hypersaline environments and is considered a model photosynthetic organism for salinity tolerance. To clarify the molecular basis for salinity tolerance, a proteomic approach has been applied for identification ...

Safflower is an important, traditional, multipurpose oil crop. This was to investigate the effect of different salinity levels on morphological, physiological, biochemical and antioxidant response of two safflower cultivars (Carthamus tinctorius L. cultivar TSF1 and cultivar SM) differing in salt tolerance. Salinity stress (0.0%, 1.0%, 1.5% and 2.0% of NaCl) was induced to safflower plants afte...

Scarcity of water for irrigation is an alarming issue of Pakistan and the problem is being magnified rapidly with the passage of time. Shortage of water is thus, a limiting factor in increasing per unit area wheat (Triticum aestivum L.) yield that is staple food of most of the people. Eventually, the gap between production and consumption is widening day by day and Pakistan is now suffering fro...

Using cereal crops as examples, we review the breeding for tolerance to the abiotic stresses of low nitrogen, drought, salinity and aluminium toxicity. All are already important abiotic stress factors that cause large and widespread yield reductions. Drought will increase in importance with climate change, the area of irrigated land that is salinized continues to increase, and the cost of inorg...
