An aniline blue squash technique for observation of urediniospore germ pores

Abstract

An aniline blue squash technique for observation of urediniospore germ pores is described. It was useful in separating three related rust species with different mean numbers of indistinct germ pores, Puccinia allii, P. mixta and Uromyces ambiguus. It may be of wider but not universal benefit in the study of germ pores of other taxa. © 1989, British Mycological Society. All rights reserved.
