  • Disclaimer
    InfoFlora compiles information on protected species as accurately as possible, taking it from the respective cantonal laws. In some cases, however, it was not possible to use the plant names as listed in the original text, but an interpretation of their taxonomy or nomenclature was necessary. The exact meaning of the categories „completely protected“ and „partially protected“ differs among the cantons.

    InfoFlora cannot guarantee that the information on the protection status is correct and complete. In case of doubts, we recommend to look up the texts of the respective cantonal law.

Threats and measures

Sukzession in Ruderalgesellschaften, keine Ausweichmöglichkeit

Genügend grosse Ruderalflächen (mit unterschiedlicher Störungsintensität) in Industriegebieten zulassen; klare Zielvorgaben und Beratung von Firmen mit solchen Bereichen

Verbesserte Saatgutreinigung, Sortenzüchtung,Ersatz des Dinkels durch ertragreichere Getreidesorten

Extensive (Dinkel-) Getreideäcker in thermisch günstigen Lagen im früheren Anbaugebiet des Dinkels anlegen oder fördern (z. B. im Rahmen der Erhaltung alter Getreidesorten, auf Grenzertragsflächen); Verzicht auf perfekte Saatgutreinigung

Kleine Zahl der Fundorte

Schaffung weiterer günstiger Ersatzlebensräume z. B. entlang von Bahnlinien; Information der Bevölkerung über den Zweck von «ungepflegten» Flächen; sofern noch Fundstellen bestätigt werden: ex-situ-Kultur für Erhaltungskulturen und allfällige spätere Wiederansiedlungen; Erfolgskontrolle der Massnahmen gewährleisten;für vollständigen Schutz vorgeschlagen (NHV, z. Z. in Revision)

Intensive Bewirtschaftung (tiefe Bodenbearbeitung, Düngung, Herbizide)

Nur geringe, wenig tiefe mechanische Bodenbearbeitung; keine oder geringe Düngung; dosierter Herbizideinsatz nur im Extremfall

Summary of stem anatomy (German)

Umriss rund oder oval. Leitbündel in mehreren Reihen. Kleine Interzellularen, oft dreieckig. Epidermiszellen verholzt. Chlorenchyma in tangential verlängerten Gruppen.

Description

Culm-diameter 2-5 mm, wall large, radius of culm in relation to wall thickness 1:0.5. Outline circular with a smooth surface. Culm-center hollow and surrounded by a few thin-walled, not lignified cells. Epidermis-cells thin-walled all around. Large vascular bundles arranged in 2-3 peripheral rows. Chlorenchyma in round, oval, square or rectangular groups. Sclerenchyma in a large, peripheral continuous belt (> 3 cells). Cells thick-walled. Sclerenchymatic sheath bilateral, large at both radial ends of vascular bundles. Largest vessels in vascular bundles in lateral position. Largest vessel in the bundle 50-100 μm. Cavities (intercellulars) between parenchyma-cells present, small, often triangular. Distinct cavities (intercellulars) in the protoxylem area of vascular bundles.
