Determinants of the phytotoxicity of platinum [PDF]
, 2000 Studies performed to demonstrate the phytotoxic potency of heavy metals are frequently carried out in nutrient solutions. Owing to their simple methodology, such experiments can serve only to provide an initial orientation. They must be supplemented by experiments which more accurately simulate the complex interactions between plant roots and the ...

Municipal Sludge-induced Phytotoxicity
Alternatives to Laboratory Animals, 2005Municipal sludge (MS), containing various types of environmental pollutants, can exert phytotoxic effects in plants. Seed germination, chlorophyll content, plant weight, root and shoot growth, and metal levels, were measured as endpoints to assess the phytotoxic effects of leachates of MS from Lucknow city in three plants, Triticum aestivum, Brassica ...

Phytotoxic lesions of chromium in maize
Chemosphere, 2003Chromium (Cr) is fairly abundant in the earth's crust and ranks fourth among the 29 elements of biological importance. Besides natural sources, Cr enters biotic components of the ecosystem in various ways. Of other major industrial sources, tanning and chrome-plating industries are prominent sources.

Phytotoxicity of orellanine, a mushroom toxin
Toxicon, 1987Orellanine, a toxic principle of Cortinarius orellanus Fr., efficiently inhibited the photosynthetic activity of duckweed, Lemna minor L., at a concentration of 0.4 mM. A lower concentration (0.06 mM) blocked the O2 production in isolated spinach class A chloroplasts.

Publisher Summary This chapter discusses the phytotoxicity, damage caused to plants by insects. Insects damage plants in many ways, but the most common type of damage is the removal of plant tissues, as in the familiar examples of caterpillars, beetles, and grasshoppers whose feeding creates noticeable holes or even the wholesale removal of leaves ...

Synthesis and Phytotoxic Activity of Ozonides
Journal of Agricultural and Food Chemistry, 2008The [4 + 3] cycloaddition of the proper furans with the oxyallyl cation, generated in situ from 2,4-dibromopentan-3-one, produced a series of 8-oxabicyclo [3.2.1]oct-6-en-3-ones. Exposure of the oxabicycles to ozone afforded the corresponding 8,9,10,11-tetraoxatricyclo[5.2.1.1 (2,6)]undecan-4-ones in variable yields (7-100%).

Herbicides and Selective Phytotoxicity
Annual Review of Plant Physiology, 1951The field of herbicides and phytotoxicity continues to command the widespread interest of workers in all parts of the world. In spite of the fact that this subject was fully reviewed by Norman et al. (209) in the previous volume, the present review contains more than 300 new references. With such a volume of work ranging over the many subjects relating

Inhibition of Glyphosate Phytotoxicity
Weed Science, 1979Effects of seven herbicides and two herbicide formulations on the phytotoxicity of glyphosate {[N-(phosphonomethyl)glycine]} were studied in the greenhouse. All herbicide formulations tested reduced glyphosate toxicity; the degree of reduction among herbicides varied. Type of formulation did not alter the reducing effects of propazine [2-chloro-4,6-bis(

The phytotoxicity of mercury vapor
Water, Air, and Soil Pollution, 1984Seed germination and early growth were unexpectedly resistant to Hg-vapor at air saturation levels (14 μg L−1). Among 15 species and cultivars tested, inhibition of shoot or root growth in excess of 50% was not seen, but occasional stimulation was noted.

Abstract The increase of aluminum (Al) bioavailability in the soil seriously compromises plant growth and crop production. Al phytotoxicity highly depends on the interactions between Al and root cells, apoplast and symplast, which are influenced by genotype and environmental conditions (e.g., soil pH, nutrients availability).
