abstract osmoreguolation is a physiological processes that plant cell uses to maintain water balance and it is generally caused by metabolite accumulation inside the cell. inoculated legumes by some drought tolerant sinorhizobium isolates helps osmoreguolation by increasing biological nitrogen fixation. in order to find some drought tolerant sinorhizobium isolates, 80 isolates were isolated and...

A series of water-soluble glycofullerenes containing up to 24 fucose residues have been prepared. These compounds were tested against the two bacterial fucose-binding lectins LecB and RSL, and C60(E)12 bearing 24 fucose residues appeared to be the best known inhibitor of both lectins to date. We have shown that increasing both the valency and the length of the spacer between the central core an...

Mature coconut water (MCW) is a natural beverage and main by-product of various processing industries such as virgin oil, chips, milk, etc. In spite huge benefits, MCW’s short shelf life limits its market potential. this context, the present study investigates effect ultrasonic parameters, amplitude (50%, 60% 70%) time (5 min, 10 min 15 min), on microbial population quality profile (pH, total s...

introduction drought stress is the most important growth limiting factor for crop production. sugar accumulation under drought stress strengthens and stabilizes cell membranes and maintains the water absorption and turgid property. under stress conditions, proline will also maintain the turgor pressure and decreased the damages caused to plant membrane. although proline concentrations may have ...

Seasonal changes in antioxidant enzymes activities, amount of water, ash, proline and soluble sugars were surveyed during this research in four halophyte species of Varamin County, Tehran, Iran: Salsola turcomanica Litwin, Suaeda arcuata Bunge, Tamarix leptopetala Bunge and Cressa cretica L. Plants were collected randomly from their natural habitats in spring and summer. Activity of these enzym...

Pond-cypress, a deciduous conifer, is a dominant canopy species in depressional wetlands of the southeastern Coastal Plain (SCP). Extensive premature decline and death of pond-cypress trees in central Florida have been attributed to hydroperiod alterations due to excessive withdrawals of ground water from the Floridan aquifer. One factor identified in the decline process is basal decay, which m...

ABSTRACT The semi-arid region of northeastern Brazil is characterized by irregular precipitation and high evapotranspiration, with a common occurrence water sources concentration salts. In this context, study aimed to evaluate the post-harvest fruit quality grafted guava cv. Paluma under brackish irrigation foliar application salicylic acid. experiment was conducted greenhouse conditions in Cam...

Seasonal variations may influence the quality and quantity of biologically active ingredients in medicinal plants. Rosemary (Rosmarinus officinalis L.) a member of the Lamiaceae family, contains valuable antioxidant, anticancer and antibacterial substances, including Carnosic acid (CA). Here, the fluctuations of important active compounds present in rosemary leaf extracts collected in Golestan,...

The effects of 2 concentrations of kinetin, i.e., 2 and 4 mM together with 2 levels of drought stress, i.e., moderate (35% soil saturation capacity) and severe (20% soil saturation capacity) were investigated on the growth parameters of tomato including fresh and dry leaf weight, leaf number, leaf surface area, fruit number, fruit weight, and enzymatic antioxidants. To this end, first tomato pl...
