SALICYLIC ACID DECREASES Cd TOXICITY IN MAIZE PLANTS
The present study is focused on the possible mediatory role of salicylic acid (SA) in photosynthesis under cadmium (Cd) toxicity. Maize seeds were sterilized and divided into two groups. One half of the seeds was presoaked in 500 μM SA solution for 6 h and then both groups were allowed to germinate for 3 days. Plants were grown for 12 days in Hoagland solution at 22/18 oC under 16/8-h light/ da...

15 صفحه اولCadmium Toxicity: The Investigation of Cd Toxic Level In Different Organs of Cherry Tomato Plant and The Effect of Cd Accumulation
This research was done in hydroponic environment in greenhouse at 3 stages (vegetative, flowering and full product) in 5 concentrations of Cd (0.1, 0.3, 0.9, 2.7, and 10 mm) for investigating physiological and biological effects. This study revealed that the increase of Cd concentration in understudy treatments causes the 49% reduction of sugar solution in 10 mm treatment. On the other hand, th...
متن کاملDifferential Accumulation of Salicylic Acid and Salicylic Acid-Sensitive Catalase in Different Rice Tissues.
We previously proposed that salicylic acid (SA)-sensitive catalases serve as biological targets of SA in plant defense responses. To further examine the role of SA-sensitive catalases, we have analyzed the relationship between SA levels and SA sensitivity of catalases in different rice (Oryza sativa) tissues. We show here that, whereas rice shoots contain extremely high levels of free SA, as pr...
متن کاملPb and Cd accumulation in Avicennia marina from Qeshm Island,
The accumulation of heavy metals Pb and Cd in the mangrove, Avicennia marina, was studied on the southern coast of Iran, particularly on and near Qeshm Island in the Persian Gulf. The samples were collected from 7 stations which they were analyzed by flame Atomic absorption spectrophotometer after chemical digestion. Maximum Pb and Cd in leaves are (34.50, 3.52 ppm) and minimum of them are in ...
