The present study was conducted to evaluate the ameliorating effect of 5-aminolevulinic acid (ALA) on physiological and biochemical changes of induced NaCl-salinity stress on in vitro shoot and callus cultured of red-fleshed apple. Shoot and callus segments of the red-flesh apple of Local Iranian genotype were cultured on MS medium containing different levels of NaCl (0, 30, 60 and 90 mM) and A...
Pollution of the environment by heavy metals, especially soil pollution with cadmium (Cd), is one of the most important environmental problems. Also, salinization of soils due to a decrease in irrigation water quality reduces plants growth. To investigate the effect of sugarcane bagasse biochars and salinity on Cd available and Cd fractions in a contaminated soil (15 mg kg-1 Cd), an experimenta...
In order to investigate the interaction of mycorrhizal fungi and salinity on growth and physiological characteristics of sweet corn, a greenhouse experiment was conducted at College of Agriculture, Shiraz University, in 2014. The experimental design was factorial based on Completely Randomized Design in three replications. Treatments included salinity at four levels (0.4 (control), 4, 7, 10 dS ...
scion-rootstock combination and level of salinity affect growth characteristics and concentration of nutrition elements of almond leaves and roots. in this research, effects of salinity stress were investigated on growth characteristics and nutrient concentration of almond leaves and roots by completely randomized design (crd), with two factors, genotype and water salinity with three replicatio...
The present study was conducted to evaluate the impact of drought and salinity stresses on germination, seedling growth and cell membrane stability of anise (Pimpinella anisum) and fennel (Foeniculum vulgare) in two separate experiments, using a completely randomized design with three replications in Islamic Azad University, Shoushtar Branch in 2013. Drought stress was applied by PEG 6000 and i...
Epigenetic modification contributes to the regulation of gene expression and plant development under salinity stress. Here we describe the identification of 49 soybean transcription factors by microarray analysis as being inducible by salinity stress. A semi-quantitative RT-PCR-based expression assay confirmed the salinity stress inducibility of 45 of these 49 transcription factors, and showed ...
Taking into account the high potential of cyanobacteria to tolerate salinity stress, researches have evaluated the morphological and physiological behavior of these microorganisms in recent years. This study is conducted to investigate the impact of different concentrations of NaCl on the morphological and physiological traits of Nostoc sp. ISC 101. Biometrical and morphological observations ar...
Salinity is a serious problem for expansion of agriculture, especially in arid and semi-arid regions. On the other hand, various benefits of soilless culture have caused the expansion of this system in these areas. In order to investigate the effect of different levels of salicylic acid and salinity stress on vegetative and physiological characteristics of eggplant, a factorial experiment was c...
In this paper twelve barley (Hordeum vulgare L.) genotypes were screened for salt tolerance during seed germination in the Crop Production Department, Faculty of Agriculture, Jordan University of Science and Technology, Irbid, Jordan. To evaluate salt tolerance during germination, 30 seeds of each genotype were placed on towel paper in 9 cm Petri dishes containing 20 mL distilled water or 1:1 M...
Salt stress is one of the major factors limiting crop productivity worldwide. Grain amaranth is new crop with high yield potential and good nutrition value which can be a good substitute for salt-sensitive crops in saline areas. This research was conducted to evaluate different level of salinity and applied salinity stress at several growth stages on some morphological and physiological traits ...
