Abstract
THE search for a thinning spray to be used on peaches has shown that N-l-naphthyl phthalamic acid promotes abscission of peach fruits1. This preliminary report compares the size, content of natural auxin, and embryological development of adhering and abscising fruits of Halehaven peach trees sprayed with N-l-naphthyl phthalamic acid at petal fall.
