Abstract

Anatomical and morphological similarities in flower and fruit development exist among cultivars of peach and nectarine [Prunus persica (L.) Batsch ‘June Gold’, ‘Harvester’, and ‘ArmKing’] and some other members of Rosaceae. The abscission of peach and nectarine fruit involves events at 3 recognizable zones between the fruit and the stem. Of these 3 zones, the most distal is the most complex and does not form a discrete separation layer. The basal zone is predominant in samples treated with the ethylene releasing compound, CGA-15281 [(2-chloroethyl) methyl-bis (phenlymethoxy) silane]. Mature fruit from untreated plants generally abscise at the most distal zone.
