background and objectives: infunction of the photosynthetic apparatus of halophytes plays an important role in their salinity tolerance. kochia as a halophyte, is of high ability in biomass production in salinity stress conditions. thus study photosynthesis and the related factors salinity stress can provide appropriate physiological view for better understanding of the plant mechanisms of in s...

With green technologies, the damages caused by agro-technological wastes to environment are eliminated. In our study, it was aimed both prevent harm of olive oil waste and produce lipase enzyme, which is an important biotechnological product.. E. faecium E68 obtained from milk dairy products used in production enzyme. developed medium containing 10% waste, pH6.5, at 37oC with 120 rpm agitation ...

The evaluation of biochemical markers is important for the understanding of the mechanisms of tolerance to salinity of Phaseolus beans. We have evaluated several growth parameters in young plants of three Phaseolus vulgaris cultivars subjected to four salinity levels (0, 50, 100, and 150 mM NaCl); one cultivar of P. coccineus, a closely related species reported as more salt tolerant than common...

Zinc has previously been reported to alleviate salinity stress in plants. In this study, we monitored various biomass and chlorophyll fluorescence parameters to determine the optimum zinc sulfate concentration that can be used as foliar spray to alleviate salinity stress in Glycine soja. The plants subjected to a series of salinity levels (NaCl concentration of 0, 100, 200, and 300 mmol L), app...

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 ...

Increased Cd toxicity at low salinity has been attributed to increased free Cd2+ ion concentration ([Cd2+]sw), but transfer to dilute seawater also stimulates physiological ionic regulation in crabs. In this study, Cd accumulation and Ca homeostasis in the shore crab (Carcinus maenas) were explored at fixed [Cd2+]sw to reveal the physiological events during sublethal Cd exposure. Crabs were exp...

The olive tree (Olea europaea L.) is one of the main crops Mediterranean region which suffers from drought and soil salinization. We assessed photosynthetic rate, leaf water content antioxidative enzyme activity (APX, GPX, SOD CAT) three Greek cultivars (‘Amfisis’, ‘Mastoidis’ ‘Lefkolia Serron’) subjected to salinity stresses. Hyperspectral reflectance data were acquired using an analytical spe...

introduction: salinity is the most significant abiotic factor limiting crop productivity and several physiological responses, including modification of ion balance, water status, mineral nutrition, stomatal behavior, photosynthetic efficiency and so on. the gf677 (prunuspersica×prunusamygdalus) is widelyusedas rootstock for peach and almond. it is mainly used as a rootstock because of its resis...

Soil salinity is one of the main problems for plant growth in agriculture, especially in countries where crops should be irrigated (Ahloowalia et al., 2004). Soil salinity has been considered a limiting factor to crop production in arid and semi arid regions of the world (Munns, 2002). Saline soils are estimated about 5 – 10% of the world’s arable land (Szabolcs, 1994), and the area affected by...
