Meadow foxtail (Alopecurus pratensis L.) belongs to family Poaceae, it is very yielding and high-quality grass, very important grass from the point of view of farming animals fattening. Phenological data were processed for period 1991 – 2009 from all CHMI phenological stations.
Temporal variability was executed in Excel, spatial variability in GIS (Clidata – GIS application, ArcView 3.2). Maps were created from average and median values for comparison.
Temporal variability was evaluated in altitudinal zones ( 801 m asl). We have also calculated pentade temperature to phenophase entrance (day of phenophase entrance was not counted), further on were analysed climatological characteristics between allergology important phenophases.
