Origin and Evolution of abscisic acid

First Known Use: 1963 year

Language of Origin: Latin

Story behind the word: The word 'abscisic acid' was coined by scientists in the mid-20th century during research on plant hormones.

Evolution of the word: Originally named 'abscisin II', the compound was later renamed to 'abscisic acid' to reflect its role in abscission (the shedding of leaves and fruits). The term has since become widely used in the field of plant physiology.
