evaluation of some antioxidant enzymes activities and metal ion accumulation in canola inoculated with p. fluorescens fy32 under salinity stress

اثر تلقیح باکتری Pseudomonas flourescens FY32 بر برخی ویژگی‌های ارقام کلزا تحت تنش شوری در سیستم هیدروپونیک

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...

Evaluation of Biochemical Response and Defense Mechanism of Wheat Antioxidant Enzymes to Salinity Stress

  Understanding the reaction form and biochemical response of wheat cultivars about the salinity stress can help to better understand the defense mechanisms and identify the indicators and biomarkers of tolerance screening for salinity stress in this strategic plant and other field crop. For this purpose, biochemical traits related to salinity tolerance of wheat cultivars were evaluated as a f...

Changes activities of antioxidant enzymes in oilseed rape in response to salinity stress

In this study, the effects of salinity stress (NaCl) on the activity of Catalase (CAT), Guaiacol Peroxidase (POD), and Superoxide dismutase (SOD) were studied in leaves of fifteen oilseed rape (Brassica napus L.) cultivars (Champlain, Hayola401, Licord, Modena, NK Aviator, NK Karibik, NK Octan, Okapy, Opera, PF, RGS, RNX 3621, SLM046, Talayeh, Zarfam). Plants were grown in a greenhouse under co...

Variation in antioxidant enzyme activities , growth and some physiological parameters of bitter melon ( ) under salinity and chromium stress Momordica charantia

Accumulation of Proline under Salinity and Heavy metal stress in Cauliflower seedlings

Salinity and heavy metals affect the growth and development of higher plants and also their productivity. In the present study, Cauliflower (Brassica oleracea var botrytis) seeds were allowed to germinate and grow in the absence (control) and presence of different concentrations (50, 100, 250, 500, 750 and 1000 μM) of NaCl, CdCl2, HgCl2 and ZnCl2. Seed germination and growth parameters of seedl...

Evaluation of salinity response through the antioxidant defense system and osmolyte accumulation in a mutant rice

In order to assess the responses of Hashemi rice genotype and its advanced mutant line under salinity stress of 100 mM Sodium chloride (NaCl) for three and six days the shoot samples were taken for biochemical analysis. This experiment was performed in split plot based on randomized complete block design with three replications. The main factor was factorial combination of saline treatmen...
