Alterations to the fine structure of the spore wall and the protoplasm are described. The exospore was more resistant to X-ray irradiation than to organic solvents, in particular diethylamine. The molecular structure of the spore wall was revealed by the X-ray effect. Resistance of the different layers of the sporomorphs to irradiation and organic solvents is important for understanding the complicated biopolymer system of the sporopollenin. %M doi:10.6165/tai.1998.43(3).215
