Abstract
Agropyron striatulum (Elymus striatulus Run.) 2n = 14, A. rechingeri Run. 2n = 28, A. junceum (L.) P.B. subsp. boreoatlanticum simonet et Guinochet (A. junceiforme Löve and Löve) 2n = 28, A. junceum (L.) P.B. subsp. mediterraneum Simonet (A. junceum (L.) P.B.) 2n = 42 and A. diae (Elymus diae Run.) 2n = 56 were studied by isoelectric focusing of seed soluble proteins. The electrophoretic phenotypes obtained from the five materials showed a striking degree of similarity. The typical protein profile was recognized to consist of 40 bands. No qualitative protein phenotypic differences were found and all observed variation concerned the intensities of some particular bands. The data of the present study combined with cytological information provided by other workers indicate that in the composition of the polyploid taxa another genome besides that of the diploid A. striatulum is not likely to participate. Consequently the polyploid taxa of A. junceum (L.) P.B. complex can be characterized as segmental allopolyploids with the same basic genome more or less modified at different ploidy levels.
