Fig. 2. — Volume distribution of the plastidial compartment in developing barley endosperm. Ninety different cellular sections of developing barley endosperm (14 DAF) were visualized by microscopy. From these micrographs the relative plastidial volumes as a percentage of the total cell volume were calculated according to the principle of Delesse (1847). A total of 335 cells were analysed. The histogram of relative volume distribution shows the range of volumes obtained for the plastidial compartment. The mean value ±SE is 50.5±0.5 for the plastidial and 49.5±0.5 for the extraplastidial compartment, respectively (n=335). The extraplastidial compartment consists mainly of cytosol.
