Arsenic (As), a metalloid and unnecessary element, is highly toxic to living organisms. It can be accumulated in the environment and enter the food chains through uptake by plants. The present study was designed to assess the response of antioxidant defense system of alfalfa to As (As0, As3+ and As5+) induced oxidative stress at four rates (0, 100, 200, and 300 µM) as a completely randomized de...
Water shortage is one of the most important limiting factors for crop production, that affected growth and yield by changing physiological conditions. This study was carried out to investigate effect of oxidative stress on antioxidant defense mechanism in Research greenhouses of Birjand University in 2014. A factorial arrangement of treatments based on randomized complete block design (Due to...
an experiment was conducted to determine the aging mechanism in safflower seed using natural aging treatment (storing seed at room temperature for six years) and accelerated aging ( incubating the seed at 41?c and close to 100% relative humidity for 4 ,8 and 12 days). the results indicated that both natural and accelerated aging reduced germination percentage, seed vigor and activity of catalas...
Changes in freezing injury percentage, lipid peroxidation (malonaldehyde formation), antioxidant enzymes activity and proline content were monitored in the leaves of olive cvs. ‘Fishomi’ and ‘Roughani’ under diff erent freezing temperatures (-5, -10, -15 and -20°C for 10 h). Th e results showed that freezing injury (determined by electrolyte leakage analysis) and malonaldehyde (MDA) content of ...
Strawberry (Fragaria × ananassa Dutch) is a widely grown fruit crop in the world due to its high aroma, taste, and nutritional value. In this study, the effect of foliar application of titanium dioxide nanoparticles on phytochemical modifications of strawberry cv. Sabrina under deficit fertigation conditions was investigated. The interaction effect of titanium dioxide nanoparticles (0, 6 and 12...
