MARKOVÁ J., URBAN Z. (1977): To the knowledge of the brown rust of couch grass in Bohemia and Moravia. 2.  Česká Mykologie 31(2): 72-80   (published: 1977)
  abstract   This is a continuation of a previous paper (Čes. Mykol. 30: 90–105, 1976). Literature data, own results as well as ecologic and historic features are discussed to support the reasons for taxonomic treatment of brown rusts of couch grass and wheat: Puccinia persistens Plow. subsp. persistens var. persistens; P. persistens var. triticina (Eriks.) Urban et Marková (leaf rust of wheat); P. persistens subsp. agropyrina (Eriks.) Urban et Marková.

MARKOVÁ J. (1976): To the knowledge of the brown rust of couch grass in Bohemia and Moravia.1.  Česká Mykologie 30(2): 90-105   (published: 1976)
  abstract   A morphometric study of teliospores of brown rust from Agropyrum spp. and wheat reveals statistically significant differences between populations. Differences in teliospore dimensions support taxonomic distinctions among rust forms.

ONDRÁČKOVÁ J., URBAN Z. (1972): Infection experiments with Puccinia perplexans Plow. var. triticina (Eriks.) Urban f. sp. persistens in Bohemia.  Česká Mykologie 26(1): 9-22   (published: 1972)
  abstract   The life cycle of the brown rust of Couch grass from 3 Bohemian localities was studied. It was stated that there are at least 2 different physiologic races of the rust. One of them parasitizing Agropyrum × apiculatum in the mountains České středohoří is obligatorily heteroecious alternating with Thalictrum minus. In this respect it differs from 2 other collections on Agropyrum repens (originating from Central and South Bohemia) in which host alternation does not take place. Moreover, last mentioned races differ in their pathogenicity from the obligatorily heteroecious rust. For all urediniospore collections infection type on 33 grass species, 26 wheat varieties, 20 rye varieties, 1 barley variety and 4 wheat-couch grass hybrids and 2 wheat-rye hybrids was stated. Some species of Bromus and Couch grass were compatible. Wheats and their hybrids showed necrotic spots only. A part of rye plants inoculated produced uredinia of the susceptible type of infection.
