Summary
Electron micrographs were made of the cellulose part of the cell walls of pollen tubes ofPetunia hybrida, grown in selfed self-sterile plants and on agar plates. In sterile plants the tubes showed denser membranes but the orientation of the cellulose strands is the same as in cells germinated on agar.
