Abstract

Abstract Excised ‘Staymared’ and ‘Golden Delicious’ apple pedicels translocated more indoleacetic acid (IAA) basipetally as the flower opened and fruit set, but basipetal and acropetal sucrose translocation did not increase seasonally. In both cultivars translocation of sucrose was not affected by spraying the tree with naphthaleneacetic acid (NAA) or 1-naphthyl methylcarbamate (Sevin). Basipetal translocation of IAA was increased on the tenth day following treatment with NAA. Pedicels of fruit about to abscise had lost much of their capacity for basipetal IAA translocation but not for sucrose translocation. The thinning effect of NAA and Sevin apparently was not due to their effect on translocation of auxin or sucrose by the pedicel.
