The effect of sawdust obtained from the wood of different tree species on
the rooting of softwood cuttings of sour cherry and hazelnut under
artificial mist was studied. Willow, pear, hazel, and apple sawdust
assured a higher percentage of rooted cuttings of the sour cherry cultivar
Schattenmorelle than the control medium the difference being significant.
A lower percentage of rooting was obtained in pine, sour cherry, plum, and
walnut sawdust but the differences, when compared with the control medium
were non-significant. Softwood cuttings of the hazelnut cultivar Hall's
Giant rooted in a higher percentage in all the investigated kinds of
sawdust than in the control medium, but significant differences were
observed only in sawdust from cherry wood.
The results of the bean hypocotyl bioassay confirmed the high rhizogenic activity of the sawdust
itself and of water extract obtained from it. The results obtained in the
present study seem to indicate that the positive effect of sawdust on the
rooting of cuttings is related rather to its chemical than its physical properties.
