aux·in

(ôk′sĭn)
Any of various hormones or similar substances that promote and regulate the growth and development of plants. Auxins are produced in areas (called the meristem) in which new plant cells are formed. Auxins are also produced artificially in laboratories for purposes such as speeding growth and regulating how fast a fruit will ripen.
