Salinity is an important abiotic stress that reduces growth and productivity of different crops. In many agricultural soils cyanobacteria or blue green algae are the prominent inhabitants, where they potentially contribute to improve soil fertility and crop productivity under normal and abiotic stress conditions. Glycinebetaine is an osmoprtectant compound improving plant tolerance to abiotic s...

Soil and water salinity are the most important problems that limit crop production, especially in the arid and semi-arid regions. This study was conducted to investigate the effect of growth-promoting bacteria and selenium nanoparticle pretreatment on increasing the tolerance of the Chenopodium quinoa plant to salinity. A factorial experiment was conducted in a completely randomized design with...

The present study was conducted to assess the physiological and biochemical responses of winter vegetable radish (Raphanus sativus L.) to salinity stress. Salt stress markedly reduced biomass production of both radish varieties. Shoot fresh and dry weights were significantly reduced under salt stress, higher reduction was found at 120 mM NaCl as compared. Salt stress significantly reduced chlor...

a factorial experiment based on completely randomized design (crd) was performed with three replications to investigate the interaction between salinity and nh+4 / no-3 ratio on olive saplings. four levels of salinity (0, 50, 100,150 mm) and different ratios of nh+4/ no-3 (0:14, 2:12, 4:10, 6:8) were applied on one-year old olive saplings grown in perlite: sand media (1:1). results indicated th...

A pot experiment was conducted to assess the effect of different salinity levels on growth and ion contents of black seeds (Nigella sativa L.) at Shakarganj Botanic Garden, Jhang, Pakistan. There were three levels of NaCl salinity as 0 (control), 3 dS/m and 6 dS/m. All growth attributes such as fresh and dry shoot weights, shoot length decreased with increase in salinity levels, but in contrast...

Understanding the salinity stress mechanisms is essential for crop improvement and sustainable agriculture. Salinity prepotent abiotic compared with other stresses that decrease growth development, reducing production creating food security-related threats. Therefore, input of metal oxide nanoparticles (NPs) such as zinc (ZnO-NPs) can improve salt tolerance in plants, especially early stage gro...

BACKGROUND Olive (Olea europaea L.) cultivation is rapidly expanding and low quality saline water is often used for irrigation. The molecular basis of salt tolerance in olive, though, has not yet been investigated at a system level. In this study a comparative transcriptomics approach was used as a tool to unravel gene regulatory networks underlying salinity response in olive trees by simulatin...

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...

Sugarcane (Saccharum officinarum L.) an important sugar crop, shows high sensitivity to salinity at various growth stages. This study was conducted to determine the comparative response of a salt-tolerant (CP-4333) and a salt-sensitive (CP-71-3002) sugarcane clone to the toxic or osmotic effects of sodium chloride at two growth stages. Clones indicated significant differences in terms of reduct...
