Salinity is one of the most important non- biological stresses which limit the production of agricultural yields in dry and semi arid regions. Humic acid as an organic acid and ascorbate as a powerful antioxidant can improve yield of plants under salt stress. In order to investigation effects of salinity and its interaction with ascorbate and humic acid on growth, photosynthetic pigments conten...

In order to investigate effects of Azomite application in reducing salinity stress in basil herb, a pot factorial experiment based on completely randomized design with three replications was conducted in the research greenhouse of Agriculture Faculty, Ferdowsi University of Mashhad. Treatments were consisted of salinity stress at three levels (0, 50 and 100 mM) as the first factor and the appli...

Chamomile (Tanacetum parthenium) is one of the most valuable medicinal plants and its dried flowers contain many terpenoids and flavonoids contributing to its medicinal properties. Salinity is one of the main limiting factors of plants growth in the world, especially in arid and semi-arid areas. Currently, biological methods use widely to contrast the soil salinity. To study of the effect of me...

Plant growth promoting rhizobacteria are known as an alternative to chemical fertilizers, which are able to reduce the harmful effects of non-biological stresses such as salinity and increase soil fertility and crop production. This study was conducted to investigate the effect of inoculation of Pseudomonas fluorescens strain FY32 on a number of morphological characters in canola cultivars unde...

In order to investigate the effect of putrescin and salicylic acid on some physiological and antioxidant properties of stevia under salinity stress, a factorial experiment was conducted in a completely randomized design with three replications. In this experiment, samples were exposed to different concentrations of putrescine (0, 0.5 and 1 mM), salicylic acid (0 and 0.5 mM) and salinity (0, 75 ...

Soil salinity is a serious environmental problem that has negative impacts on growth and production of plants. On the other hand, application of chitosan has recently been increased to enhance the resistance to different stresses, such as salinity. In order to study the effect of chitosan seed-priming on alleviation of salinity stress in fenugreek (Trigonella foenum-graecum L.) a factorial expe...

Populus euphratica tree is a species naturally growing in riparian zones of rivers in arid and semiarid region where seasonal flooding and soil waterloging provides the conditions for this species. The aim of current study was to assess survival, growth characteristics and biomass allocation of Populus euphratica seedlings exposed to combined flooding- salinity stress at four levels including c...
