Basal or apical parts of grapevine cuttings as well as entire cuttings were treated with hot water at a temperature of 50 °c for 30 min. Root initiation was delayed following HWT of entire cuttings and treatment of the basal parts only. HWT of the apical parts of cuttings resulted in a marked stimulating effect on time of sprouting, root initiation, mean number and mass of roots.
Einfluß der Warmwasserbehandlung auf Austrieb und Wurzelbildung von Rebenstecklingen
Dreiaugenstecklinge der Rebsorten Salt Creek (Ramsey) und Jacquez (mittleres und unteres Auge geblendet) wurden 30 min lang partiell oder gänzlich in 50 °c warmes Wasser getaucht. Wurden die ganzen Stecklinge oder der basale Pol behandelt, so war die Wurzelbildung gegenüber der Kontrolle verzögert. Durch Warmwasserbehandlung des apikalen Pols wurden dagegen der Austrieb und die Bewurzelung beträchtlich beschleunigt und die Anzahl und Masse der Wurzeln vermehrt.
