Following the Initiation and Development of Individual Leaf Primordia at the Level of the Shoot Apical Meristem: The Case of Distichous Phyllotaxis in Begonia

摘要

Background and AimsBy using the technique of replicas of a developing apex it is possible to obtain a direct measure of phyllotactic parameters (plastochrone and platochronic ratio) involved in the initiation of two successive primordia at the level of the SAM. The goal of this study is to compare, in a real time setting, the value of phyllotactic parameters in distichous sytems using Begonia as a case study, with the value of the same parameters in spiral phyllotactic systems.
