Abstract Ultrastructural changes in the abscission zone between ovary wall and floral disc were followed during abscission of young lemon (Citrus limon (L.) Burm. f. cultivar 'Villafranca') fruit explants. Although some cell breakage was observed by light and scanning electron microscopy as well as cell wall dissolution, only middle lamella dissolution was observed by transmission electron microscopy, strongly suggesting that pectic substance dissolution is the primary cause of cell separation. Prior to cell separation the middle lamella of the cell wall stained deeply, the amount of rough endoplasmic reticulum (ER) profiles increased, and the number of Golgi bodies also increased. However no change in mitochondria or chloroplast structure was observed before cell separations, and no microbodies were observed. In Ethephon (2-chloroethylphosphonic acid)-treated explants, essentially similar cytoplasmic and cell wall changes occurred during the course of abscission, but the changes were more rapid.
