Unter sterilen Bedingungen bildet Aureobasidium pullulans mit Vitis riparia eine Mykorrhiza, die als dichter plektenchymatischer Überzug auf den Wurzeln in Erscheinung tritt. Zwischen den Rindenzellen bildet sich ein mehr oder weniger ausgeprägtes HARTIGsches Netz. Der Pilz scheidet einen Wuchsstoff aus, der schon vor dem Hyphenkontakt bei sterilen Stecklingen ein Streckungswachstum auslöst.
Studies on artificial mycorrhiza in Vitis riparia
Under sterile conditions a mycorrhiza is formed between Aureobasidium pullulans and Vitis riparia. The mycelium forms a dense plectenchymatic layer an the roots and a more or less complete HARTIG net between the cells of the cortex. The fungus produces a growth substance inducing internodial elongation of the plantlet even before a hyphal contact is achieved.
