Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]
The plant roots must absorb the heavy metal. The plant must chelate the metal to both protect itself and make the metal more mobile (this can also happen before the metal is absorbed). Chelation is a process by which a metal is surrounded and chemically bonded to an organic compound. The plant moves the chelated metal to a place to safely store it.
Forest dieback presents itself in many ways: falling off of leaves and needles, discolouration of leaves and needles, thinning of the crowns of trees, dead stands of trees of a certain age, and changes in the roots of the trees. It also has many dynamic forms. A stand of trees can exhibit mild symptoms, extreme symptoms, or even death.
Detoxification (often shortened to detox and sometimes called body cleansing) is a type of alternative-medicine treatment which aims to rid the body of unspecified "toxins" – substances that proponents claim accumulate in the body over time and have undesirable short-term or long-term effects on individual health.
The earth to nurture the plant, the air from which it feeds, the sun or fire to enable it to impart its power, and water to collect and be enriched with its beneficent magnetic healing. By the time of his death in 1936 at 50 years of age, Bach had created a system of 38 different flower remedies along with their corresponding theories of ailments.
Wilting diminishes the plant's ability to transpireļ¼reproduce and grow. Permanent wilting leads to the plant dying. Symptoms of wilting and blights resemble one another. The plants may recover during the night when evaporation is reduced as the stomata closes. [2] In woody plants, reduced water availability leads to cavitation of the xylem.
Ibogaine is a psychoactive indole alkaloid obtained either by extraction from plants in the family Apocynaceae such as Tabernanthe iboga, Voacanga africana, and Tabernaemontana undulata or by semi-synthesis from the precursor compound voacangine, another plant alkaloid. [1] [2] The total synthesis of ibogaine was described in 1956. [5]
Hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
