Wheatgrass variability (Agropyron, Sect. Elytrigia) in a native collection from Transylvania, Romania. I. Agropyron intermedium Complex (in English)

Agropyron intermedium sl. variability  has been studied in 36 populations collected  in Transylvania, in order to identify valuable germplasm for erosion control. Open pollination fertility of the samples calculate on seeds per flower basis ranged from 0% to 48,7%. Average values and extremes of some morphological characteristics have also been established. About 20% of  the collected samples belong to ssp. trichophorum (Link.) Volk. and one population with special growth habit and phenotype has been identified as ssp. pulcherrimum (Grossh.). High germination energy and rapid seedling growth have been observed in populations selected for higher OP fertility as compared to A. repens populations.
