Influences of calcium silicate on chemical forms and subcellular distribution of cadmium in Amaranthus hypochondriacus L.
A pot experiment was conducted to investigate the effects of calcium silicate (CS) on the subcellular distribution and chemical forms of cadmium (Cd) in grain amaranths (Amaranthus hypochondriacus L. Cv. 'K112') grown in a Cd contaminated soil. Results showed that the dry weight and the photosynthetic pigments contents in grain amaranths increased significantly with the increasing doses of CS t...
متن کاملSubcellular distribution and chemical forms of cadmium in two hot pepper cultivars differing in cadmium accumulation.
A greenhouse experiment was conducted to compare the subcellular distribution and chemical forms of cadmium (Cd) in roots, stems, leaves, and fruits between a low-Cd cultivar (Yeshengchaotianjiao, YCT) and a high-Cd cultivar (Jinfuzaohuangjiao, JFZ) of hot pepper (Capsicum annuum L.). The Cd concentrations in the root's subcellular fractions, and in all chemical forms in roots, were 1.85-4.88- ...
متن کاملArbuscular Mycorrhizal Colonization Alters Subcellular Distribution and Chemical Forms of Cadmium in Medicago sativa L. and Resists Cadmium Toxicity
Some plants can tolerate and even detoxify soils contaminated with heavy metals. This detoxification ability may depend on what chemical forms of metals are taken up by plants and how the plants distribute the toxins in their tissues. This, in turn, may have an important impact on phytoremediation. We investigated the impact of arbuscular mycorrhizal (AM) fungus, Glomus intraradices, on the sub...
متن کاملCadmium uptake, chemical forms, subcellular distribution, and accumulation in Echinodorus osiris Rataj.
Phytoremediation is a technology for extracting or inactivating pollutants in soil. Echinodorus osiris (E. osiris) is a fast growing perennial wetland plant that is common in tropical and subtropical areas and has a high tolerance to cadmium (Cd). However, the absorption dynamics, subcellular distribution and accumulation of Cd by E. osiris had not been investigated. In this paper, hydroponic e...
متن کاملEffects of Exogenous Calcium on the Growth and Physiological Traits of Garlic Seedlings under Cadmium Stress
In this study, the alleviation effect of exogenous calcium (Ca) against cadmium (Cd) toxicity to growth, photosynthetic characteristics, antioxidant properties, and absorption of nutrients was explored in nutrient solution-cultured garlic seedlings. The results indicated that Cd significantly inhibited the growth of garlic seedlings as well as reduced the chlorophyll content, net photosynthetic...
