Aspirin is among the most popular remedies used by people for stress. Researchers at the National Center for Atmospheric Research were surprised to discover that stressed plants an aspirin like chemical that can be detected in the air above the plants. The chemical may be a sort of immune response that helps protect the plants. Acetylsalicylic acid, or aspirin, was originally derived from the tree bark, so scientists knew it was a compound made by plants .But it was never seem to be emitted as a gas.
Such compounds can combine with industrial emissions to affect pollution and they can influence local climate. The tress were already stressed by drought, and levels of methyl salicylate rose with unseasonably cool night-time temperatures, especially when it is quickly warmed up the next day. The finding raises the possibility that farmers may eventually be able to start monitoring plants for early signs of disease.
