Volatiles released as cut grass dries
In laboratory measurements, cut grass and clover released a burst of volatile compounds when cut, followed by a second, more intense emission lasting several hours as the plants began to dry, with enhanced emissions of methanol, acetaldehyde, acetone and butanone besides the (Z)-3-hexenal, (Z)-3-hexenol and hexenyl acetate released on wounding.
Freshly cut grass and clover drying in a laboratory; the source does not mention haymaking or study finished hay, and it measures emissions, not odour.
The statement the claim rests on was found word for word in the abstract fetched from the named service, and an editor read the full abstract against every part of the claim. Abstract from Crossref (api.crossref.org).
