Processus de croissance et d'organogenese chez le pommier cv Golden Delicious

Abstract

Growth and organogenesis processes in apple tree cv Golden Delicious. This work aims to focus on the organogenetic activity, growth and histological processes in the shoot apical meristem of apple cv Golden Delicious. In that perspective we studied: the organogenesis of the ""bourse"" shoot during vegetative period; the internodal and leaf growth of the 2 types of ""bourse"" shoots (long and short); the histological process of apical meristem during the development of these two structures; the growth stopping and the beginning of terminal bud formation characterized by a progressive heteroblasty within the long ""bourse"" shoots and an abrupt heteroblasty within the short ""bourse"" shoots.
