AMELIORATION OF NICKEL TOXICITY IN SOYBEAN PLANTS BY GIBBERELLIN AND ASCORBIC ACID
The interactive effects of nickel (Ni) and ascorbic acid (AsA) and gibberellin (GA3) on soybean seedlings (Glycine max L. cv. Union × Elf) were examined. Seven-day old hydroponically-grown seedlings were exposed to NiCl2, 6H2O (0.5 mM), either with or without AsA (1 mM) or GA3 (0.05 mM) or AsA (1 mM) plus GA3 (0.05 mM), for five days. Nickel toxicity symptoms, such as formation of reddish-brown...
متن کاملOccurrence, physiological responses and toxicity of nickel in plants
The focus of the review is on the specific aspects of nickel’s effects on growth, morphology, photosynthesis, mineral nutrition and enzyme activity of plants. The mobility of nickel in the environment and the consequent contamination in soil and water is of great concern. Also, the detrimental effects of excessive nickel on plant growth have been well known for many years. Toxic effects of nick...
متن کاملSalicylic Acid Protects Photosynthesis against Cadmium Toxicity in Pea Plants
In the present study we have investigated the possible mediatory role of salicylic acid (SA) in protecting photosynthesis against cadmium (Cd) toxicity. The exposure of pea plants to increasing Cd concentrations (0.5, 1.0, 2.0 and 5.0 µM) during early stages of their establishment caused a gradual decrease in shoot and root fresh weight accumulation, the rate of CO 2 fixation and the activity o...
متن کاملLiver and Cadmium Toxicity
Cadmium (Cd) is an important industrial and environmental toxicant with many industrial applications. Cd emissions to the atmospheric, aquatic, and terrestrial environment have increased during the last century. Since Cd is not degraded in the environment, the risk of human exposure is constantly increased due to Cd also enters to the food chain [1]. Humans are generally exposed to Cd by two ma...
متن کاملCadmium Toxicity and Treatment
Cadmium is a heavy metal of considerable toxicity with destructive impact on most organ systems. It is widely distributed in humans, the chief sources of contamination being cigarette smoke, welding, and contaminated food and beverages. Toxic impacts are discussed and appear to be proportional to body burden of cadmium. Detoxification of cadmium with EDTA and other chelators is possible and has...
