Hordeum geniculatum in the Pannonian Basin: Ecological requirements and grassland vegetation on salt-affected soils

Therefore, species response curves of H. geniculatum were obtained for soil reaction and nutrients using Borhidi's indicator values and LOESS smoother response model in the programme CANOCO. Our data showed that H. geniculatum can be regarded as an obligate halophyte preferring slightly to moderately saline soils with relatively high content of nutrients.

The Hordeetum hystricis association, indicating grazed vegetation on salt-rich soils, is a plant community that occurs only in central and southeastern Europe. Because this plant community has only been documented in a relatively small area, details about its vegetation ecology are inaccurate. Therefore, the ecology and species composition of this community were studied in three countries within the Pannonian Basin (Hungary, Serbia and Slovakia).
