The rye brine ( Bromus secalinus ) is a species of the sweet grass family (Poaceae).
description
The one-year grass has 50 to 100 cm high stalks, like the leaf sheaths in contrast to the hairy leaves are bare. The upright and spreading panicle later nods. The conspicuously large, 15 to 25 mm long spikelets are 4-7 flowered and yellow-green. The awns are only half as long as the lemmas . After the flowering period from June to September, the ripe spikelets turn yellow and the husks spread apart, their edges curling around the grain. When the wind moves the plant, the spikelets rustle audibly.
The number of chromosomes is 2n = 28.
Occurrence
The rye bristle occurs from southern, central and eastern Europe to northwestern Iran and from Siberia to northern China.
It thrives on nutrient-rich and base-rich, mostly low-lime, sandy or pure clay soils. It is a species of the Aperion spicae-venti association. In the Allgäu Alps, it rises to a maximum of 1,100 meters above sea level.
Cultural history
The rye brine exists as a weed in rye fields , much less often in wheat fields . It ripens and germinates with the rye and is harvested with it. It was previously assumed that it could turn into rye and vice versa, later it was assumed that the grass was created by humans over time. In times of need, the grains could be used to bake bread, making the bread dark and bitter. The rye brine has been known since the Neolithic Age and was spread all over the world with rye. Because of the careful cleaning of the seeds, it has become quite rare.
