Nickel: a micronutrient essential for higher plants.
Nickel was established as an essential micronutrient for the growth of temperate cereal crops. Grain from barley (Hordeum vulgare L. cv ;Onda'; containing 40 to 80 nanograms of Ni per gram dry weight) grown in solution culture with negligible Ni concentrations (< 30 nanograms of Ni per liter) exhibited greatly reduced germination rates (i.e. 50% less than grain from Ni-adequate plants) and seed...
متن کاملMolybdenum as an Essential Element for Higher Plants.
The preliminary findings that molybdenlum, in minute amounts, improved the growth of barley plants in a culture solution supplied with ammonium salts as the sole source of nitrogen (1), and that a group of seven heavy metals including molybdenum increased the growth of lettuce and asparagus (2), supported the view that the list of essential elements for higher plants is incomplete and suggested...
متن کاملHigher Plants
Contamination with 2,4,6-trinitrotoluene (TNT) is widespread at sites of past munitions manufacture. It is moderately toxic to plants and highly toxic to some animals. Some aquatic plant species have been observed to promote degradation of TNT. The degradative activity is associated with the root systems but products are found in the surrounding medium. We have examined a range of sixteen gener...
متن کاملNanoparticles and higher plants
Nanomaterials and nanotechnology have been widely applied in the world in this last decade. Nanotechnology provides the tool and the technological platforms for the study and transformation of biological systems. Few studies have focused on the effects and mechanisms of nanomaterials on plants. The results of these studies have been reported with the aim to provide further insight into connecti...
