ABSTRACT = {Fresh pollen grains of Alnus glutinosa were radiated with the same intensity of CuKα ray for four different lengths of time. The alterations in the exine ultrastructure and particularly in the biopolymer organization were investigated. The most important results are as follows: (1) The originally homogeneous substance of the ectexine layers are altered into finely granular one. (2) In particular on the surface, the degradation of the biopolymer system have been observed with several kinds of organization. (3) The original ultrastructural characteristic features of some exinous layers (e.g. lamellar endexine) disappear. (4) Endexine and the protoplasm may have the same secondary ultrastructure. (5) Peculiar effect to the bordering part of the different exinous layers have been observed with strong electron density. From these results it is concluded that X-ray has effected a heterogeneous character.},
