Avena sterilis

Avena sterilis in stock

The dove oat (Avena sterilis ) is a plant from the family of grasses ( Poaceae ).

Features

The dove oats is an annual plant, the plant height of 20 to 80, rarely to 160 cm reached.

The panicle is einseitwendig. The spikelets are 25-50 mm long. The lemmas are hairy 4 to 8 mm long. Enter at the top two membranous, 1-2 mm long teeth. At maturity, the Ährchenachse decomposes only above the glume, so that the two most fruits of a spikelet fail together.

The flowering period extends into central Europe from June to August. Germination occurs in autumn and winter.

Dissemination and locations

The dove oat is native to the Mediterranean region and Southwest Asia. In Western Europe it is naturalized and represents here a dreaded weed dar. In Central Europe it is rare and fickle, here he can not successfully overwinter mostly.

The dove oats is one of the original species of polyploid species oat (Avena sativa) and Wild Oat (Avena fatua ).

Within the species in addition to the nominate subspecies and three Nothotaxon a distinction is made:

• Avena sterilis subsp. atherantha (C. Presl ) H. Scholz
• Louis Tauber oat (Avena sterilis subsp. Ludoviciana ( Durieu ) Gillet & Magne ), is sometimes also performed as a separate species.
• Avena sterilis nothosubsp. malzevii H. Scholz ( Avena fatua = Avena sterilis × subsp. ludoviciana )
• Actual Tauber oat (Avena sterilis L. subsp. Sterilis )
• Avena sterilis subsp. trichophylla (K. Koch) Maltsev
