Soil and water salinity in semi-arid regions such as Iran have been a important threat for plant growth and agriculture. It is demonstrated that TiO2 nanoparticles can improve plant growth and increase stress tolerance in plants. Therefore, in current study, a pot experiment was conducted as factorial with completely randomized design to evaluate the effect of 3 levels of salinity (0, 50, ...
In order to study the effect of melon powdery mildew on physiological indexes different varieties, high resistant variety ‘16-6’, medium ‘04-38’, and highly susceptible ‘15B-42’ were used as materials. The activities antioxidant defense system enzymes, contents of malondialdehyde (MDA), soluble protein chlorophyll, photosynthetic indicators in leave...
A major concern on the application of sewage sludge in agricultural lands is relatively high cadmium (Cd) concentrations in these wastes which might be toxic to the plant and causes oxidative damage. Much higher Zn concentration in sewage sludge in comparison with cadmium may affect oxidative damage induced by cadmium. The aim of the present study was to investigate the effects of various conce...
The elucidation of heat tolerance mechanisms is required to combat the challenges of global warming. This study aimed to determine the antioxidant enzyme responses to heat stress, at the enzymatic activity and gene expression levels, and to investigate the antioxidative alterations associated with heat tolerance in the stems and roots of squashes using three genotypes differing in heat toleranc...
In order to evaluate the effect of sodium nitroprusside (SNP) as an effective antioxidant with advantageous impact in reducing oxidative stress in purple coneflower (Echinacea purpurea) seedlings under saline condition, a factorial experiment with arrange of completely randomized design with four replications was conducted at Sana Institute of Higher Education in 2015. In this study, the effect...
In this study, the effects of Funelliformis mosseae and Piriformospora indica on wheat growth, enzyme activity and gene expression of catalase (CAT), ascorbate peroxidase (APX) and glutathione S-transferase (GST) in wheat leaves under different cadmium (Cd) toxicity were investigated. Cd exposure reduced plant dry mass and enzyme activities of CAT and APX, but it increased GST activity. The pre...
kentucky bluegrass (poa pratensis l.) is one of the most widely used turfgrasses for home lawns, golf courses, parks, and athletic fields in temperate climates. oxidative stress caused by drought stress is a major limiting factor for grass cultivation in arid and semi-arid regions. the objective of this study was to investigate whether prohexadione-calcium (pro-ca) may play a role in promoting ...
Antioxidant enzymes play an important role in plant defense against pathogenic agents. Following the identification of the pathogen, plants produce active oxygen species (ROS) as one of their first defense responses. To maintain the balance of ROS levels and prevent their harmful effects, plants produce antioxidant peroxidase (POX), catalase (CAT), ascorbate peroxidase (APX) and superoxide dism...
the present study was laid out in order toevaluate the effect of salinity on some biochemical characterize of grapevine c.vyaghouti. the experiment was done at agricultural and natural resources research center, ilam, iran at 2014. the experiment was a completely block design (crd) with four replications. saline factor was nacl salinity in seven levels (zero, 50, 100, 150, 200 and 250 mm). grap...
Cadmium (Cd) is a phytotoxic heavy metal (HM) that can induce generation of reactive oxygen species (ROS). Arbuscular mycorrhizal fungi (AMF) are considered as bio-ameliorators that help to mitigate HM-derived oxidative stress. The objective of this study was to assess AM fungus Rhizophagus irregularis on changes in enzymatic activity and transcription of antioxidants of Medicago sativa to Cd s...
