Bromus sterilis

Dove brome ( Bromus sterilis )

The dove brome ( Bromus sterilis ) is a plant of the family Gramineae ( Poaceae ). It was introduced by man before 1492 to Central Europe and is therefore as there archaeophyte. You can survive the winter as Hemikryptophyt or as seeds ( Therophyt ).

Features

The dove brome is an annual or annual wintering herbaceous plant, reaching the heights of growth of about 30 to 60 centimeters and has bare stalks.

The loose and droopy panicle is about 10 to 15 cm long. The lower branches of the panicle are usually as long as spikelets that are not compressed. From her rough bendable branches are everywhere stand-off. The husks are always rounded on the back. The 15 to 30 mm long awn is almost twice as long as the highly annoying lemma. The spikelets are extended with the awn 4-6 cm long and the tip. The lemma is 13 to 23 mm long. The lower glume is einnervig, the top three annoying. The plant has finely toothed ligule.

Systematics and naming

The dove brome was first published in 1753 by Carl Linnaeus in Species Plantarum. Together with similar types dove brome is often separated from the genus Bromus and is then called Anisantha sterilis (L.) Nevski.

" Bromus " is the name for an oat- like plant. " Sterilizers " = " numb " must be very freely as "non- oat " interpreted, because the species was formerly assigned to the genus oats. In contrast to oat it was not used as a grain.

Locations

The dove brome is widely present in the dry Unkrautsaum ways in premolars, slightly shaded meadows, on dumps, on walls or embankments, also in clover fields and vineyards.

She prefers loose and therefore mostly sandy or stony clay soil, which should be moderately rich in nitrogen. It bears dehydration well and can even live on encrusted rubble or in wall cracks. She loves warm locations.

After Ellenberg she is a half-light plant, sub-oceanic spreading, preferably moderately nitrogen-rich sites and is a Verbandscharakterart ruderal annuals in temperate warm climate ( Sisymbrion ).

Ecology

The glumed seeds are spread by animals ( Epizoochorie ). The rough awns stick in the fur.
