Zinc toxicity in plants: a review
Planta, 2021This review highlights the most recent updated information available about Zn phytotoxicity at physiological, biochemical and molecular levels, uptake mechanisms as well as excess Zn homeostasis in plants. Zinc (Zn) is a natural component of soil in terrestrial environments and is a vital element for plant growth, as it performs imperative functions in

Toxic Plants and Phytochemicals
2018Poisonous plants produce toxic compounds which are capable of eliciting undesirable aftermath effects even death when in contact with living organisms such as plants, animal, and microorganism. These compounds include anticholinergic, severe gastrointestinal (GI) irritants, cardiac glycosides, central nervous system stimulants/hallucinogens, and ...

Abstract Manganese (Mn) toxicity in plants is often not a clearly identifiable disorder. Symptoms of Mn toxicity as well as the concentration of Mn that causes toxicity vary widely among plant species and varieties within species, perhaps because the phytotoxic mechanisms of Mn involve different biochemical pathways in different plant genotypes.

The Botanical Review, 2000
Mercury poisoning has become a problem of current interest as a result of environmental pollution on a global scale. Natural emissions of mercury form two-thirds of the input; manmade releases form about one-third. Considerable amounts of mercury may be added to agricultural land with sludge, fertilizers, lime, and manures.

The Journal of Agricultural Science, 1912
The writer has pointed out the influence that some agricultural plants have on others when grown in close proximity to them. It was demonstrated (inter alia) that a row of Sesamum indicum (gingelly), when sown at a distance of two feet from a row of Sorghum vulgare (great millet), will not mature, the plants dying after reaching a height of a few ...

Abstract The toxicity of Li to three plant species was studied to determine if there were interactions with other elements and to determine if a chelating agent modified Li toxicity. Bush beans (Phaseolus vulgarls L. C.V. Improved Tendergreen), grown in solution culture, were sensitive to 0.5 X10‐3Li which resulted in 10 μg/g in leaves, 48 in stems ...

Toxicity and uptake of nitroguanidine in plants
Bulletin of Environmental Contamination and Toxicology, 1990During the manufacture of the munition nitroguanidine (NQ), wastewater is contaminated by NQ and related by-products. Land application of the NQ-contaminated wastewater was initiated after discussions with the Kansas Department of Health and the Environment and the US Environmental Protection Agency.

The toxicity of ammonia was evaluated and an estimate is given of (mass) concentration for no adverse effect: 75 μg/m3 for a yearly average, 600 μg/m3 for 24 h and 10 000 μg/m3 for 1 h. Ammonia can cause various types of injury, including necrosis, growth reduction, growth stimulation and increased frost sensitivity.

Boron in Plants: Deficiency and Toxicity
Journal of Integrative Plant Biology, 2008Abstract Boron (B) is an essential nutrient for normal growth of higher plants, and B availability in soil and irrigation water is an important determinant of agricultural production. To date, a primordial function of B is undoubtedly its structural role in the cell wall; however, there is increasing evidence for a possible role of B in other processes
