Beta vulgaris belongs to the family Amaranthaceae and was found to have halophytic ancestors. The objective of this study was to investigate the effect of sodium chloride on seed germination, therefore the early stages of seedling growth of Beta vulgaris grown under different salinity levels (0, 100, 150 and 200 mM of NaCl) were studied. The experiment was laid out in a completely randomized de...

Fasulye (Phaseolus vulgaris L.) gıda üzerine birçok alanda kullanılır, ancak kurak ve tuzlu şartlara son derece hassastır. Kuraklık tuzluluk kültürü yapılan bitkilerin gelişimini üründen alınan verimi etkileyen önemli çevresel faktördür. Bu çalışma da amaçlanan fasulye genotiplerinde farklı tuz konsantrasyonları kuraklık dozunun tohum çimlenmesi, büyüme parametreleri etkilerini araştırmaktır. Ç...

Present work was carried out to investigate the possible role of arbuscular mycorrhizal fungi (AMF) in mitigating salinity-induced alterations in Brassica juncea L. Exposure to NaCl stress altered the morphological, physio-biochemical attributes, antioxidant activity, secondary metabolites and phytohormones in the mustard seedlings. The growth and biomass yield, leaf water content, and total ch...

In the present study, potential of ethylene as ethephon (an source) was investigated individually and in combination with split doses nitrogen (N) sulfur (S) soil treatments for removal damaging effects salt stress (100 mM NaCl) mustard (Brassica juncea L.). Plants were grown 50 mg N plus S kg−1 at sowing time an equivalent dose 20 days after [N50 + S50]0d 20d. Ethephon 200 μL L‒1 applied to co...

thyme (thymus vulgaris l.) is an aromatic and medicinal plant which is very important for the herbal industry. in this research, in vitro selection for nacl tolerance was investigated in this plant. hypocotyl and shoot explants (apical meristem and cotyledonary leaves) of sterilized seedlings were cultured in ms medium supplemented with different combinations of 2, 4-dichlorophenoxyacetic acid ...

A sensitive ESR method which allows a direct quantitative determination of nucleic acid binding affinities of proteins under physiologically relevant conditions has been applied to the gene 5 protein of bacteriophage fd. This was achieved with two spin-labeled nucleic acids, (ldT, dT)n and (lA,A)n, which served as macro-molecular spin probes in ESR competition experiments. With the two differen...

Many secondary metabolites have insecticidal efficacy against pests and may be affected by abiotic stress. However, little is known of how plants may respond to such stress as pertains the growth and development of pests. The objective of this study was to determine if and how salt stress on cotton plants affects the population dynamics of aphids. The NaCl treatment (50 mM, 100 mM, 150 mM and 2...

Plasma membrane H+-ATPase is a major integral membrane protein with a role in various physiological processes including abiotic stress response. To study the effect of NaCl on the expression pattern of a gene encoding the plasma membrane H+-ATPase, an experiment was carried out in a completely random design with three replications. A pair of specific primers was designed based on the sequence o...

In this study, rapeseed Okapi cultivar was treated under three NaCl levels (0, 50 and 100 mM) and four Zinc oxide nanoparticles (ZnO NPs) concentrations (0, 20, 40 and 80 mgL-1) at flowering stage. The experiment was performed in a completely randomized design (CRD) in the greenhouse of Biology Department of Urmia University, in 2015. Results showed that NaCl (100 mM) significantly enhanced tot...

Salinity is one of the major environmental stresses, which has deleterious effect on growth, development and yield of crops. Due to the gradual increase in soil and water salinity in the East Azarbaijan province of Iran, the garden cress cultivation in this region has always been associated with many problems. In order to evaluate the tolerance of this plant to different levels of salinity thr...
