Abstract 50% breaking point pressures of pollen grain walls of eleven species were determined. The breaking point pressures of most pollen grain walls are equivalent to those reported in the literature for other types of living cell walls such as bacterial spore coats, algal cell walls, mold sporophyte cells, and dicot suspension culture cells. The strongest pollen grain walls are two or three orders of magnitude stronger, however. Pollen grain walls are proportionately very thick in comparison to other types of cell walls. It is this thickness, not the construction or physical properties of the pollen grain wall, that most probably accounts for their strength.
