newmown

newmown is a term used to describe the distinct scent produced by freshly cut grass. This aroma is primarily a chemical defense mechanism released by plants when they are wounded. The compounds responsible for this smell are known as green leaf volatiles (GLVs). When grass blades are cut, their cells are damaged, triggering the release of these volatile organic compounds into the air.

The perception of newmown as a pleasant or nostalgic scent is a human interpretation. While the initial release of GLVs serves a biological purpose for the plant, such as signaling to insects or deterring herbivores, humans associate this smell with positive experiences like spring, summer, and outdoor activities. The specific blend of GLVs can vary depending on the type of grass and environmental conditions. Scientists have studied the chemical composition of newmown to understand its olfactory components and the biological processes behind its production. Some research suggests that humans may have an evolved predisposition to find the smell of fresh greenery comforting.
