摘要

Plants are multifaceted chemical factories that produce a multitude of compounds ranging from ethylene and methanol to complex terpenoids and nitrogen-containing alkaloids. More than 100,000 chemical products are known to be produced by plants and at least 1700 of these are known to be volatile. The study of plant volatiles has long been restricted to floral volatiles, but studies on plant volatiles emitted from the vegetative tissues are rapidly increasing. The amounts of Volatile Organic Compounds that plants disseminate into the atmosphere (VOCs or BVOCs from their ''Biogenic'' origin) are enormous. For instance, terrestrial plants are estimated to release about 500 tera-gram of carbon per year as isoprene, and probably a similar amount of carbon as monoterpenes. Other plant volatiles include e.g. green leaf volatiles, nitrogen-containing compounds and aromatic compounds. The emission of plant VOCs is not restricted to aboveground tissues but also occurs belowground from their roots.
