Wheatgrass variability (Agropyron, sect. Elytrigia) in a native collection from Transylvania. II. Agropyron repens

Abstract

In continuation of former studies regarding wheatgrass variability (Agropyron Gaertn. Sect. Elytrigia) carried out on 89 different populations collected along a transect in Transylvania (Not. Bot. Hort. Agrobot. Cluj,1979, X. 89-99) results regarding 31 A. repens (L.) P. Beauv populations are presented in this paper. Average values per population for open pollination fertility (OPF) varied betweeen 0.0-40.0%; spike length: 59-196 mm; spikelet length: 8.8-17.0 mm; number of caryopses per spike: 0.0-40 etc. The results may contribute to the explanation of some microevolutionary processes and differential spreading patterns found in Elytrigia section.
