Electron microscopy was used to study the plastid distribution during pollen development in Aloë secundiflora and A. jucunda. During the first pollen mitosis the majority of plastids is located in the centre of the microspore. Only exceptionally, single plastids are present in the region of the later generative cell. Normally the generative cell does not contain plastids. The semiquantitative analysis of the plastid content of generative cells at different developmental stages indicates that plastid transmission into the generative cell is an exceptional case in Aloë. This behaviour is considered to be typical for species of the Lycopersicon type (Hagemann 1983).
