Die Wildform hat weibliche Blüten oder Staubbeutel mit so genannten Gallblüten, deren Samenanlage verkümmert ist.
Die Befruchtung erfolgt durch die Gallwespe, einem ca. 1 mm großen Insekt.
Die Gallwespe vermag mit ihrer kurzen Legröhre ihr Ei nur in die kurzgrifflige Gallblüte zu legen, deren Fruchtknoten darauf hin anschwillt und die Entwicklung der Gallwespe sichert.
www.deidesheim.deThe wild form has female blossoms or anthers with so-called gall blossoms, showing rudimentary ovules.
The gall wasp, a very small insect of about 1 mm, is responsible for pollination.
Due to its short ovipositor, the wasp can only lay its egg on the short pistil of the gall flower until the ovary starts to swell and by doing so safeguards the continued existence of the wasp.
