Abstract:
The influence of transplanting time of Arundo donax L. in relation to vegetative clone plant propagation systems was studied for two subsequent growing seasons (2008-2011) at the Experimental farm of Catania University (Italy). A factorial experiment was carried out combining three times of transplanting (November 5th 2008, March 17th 2009, April 30th 2009), two clone propagation methods (rhizome cuttings and stem cuttings) at two soil water availability (irrigation only at the transplanting dates and irrigation from transplanting dates to end of summer). At each transplanting dates 23 mm of water were applied; in the irrigated treatment, from May to end of August, other 250.0 mm of water were applied. The time span between planting to emergence of the first stems has been 168 days (first planting dates), 41 days and 24 days for second and third planting dates respectively. Stem cuttings have shown a good plant establishment in the first and second planting dates; furthermore in all planting dates showed a positive effect on planting density due to supplementary irrigation whereas rhizomes did not. On the contrary rhizomes have a good establishment in the second and third planting dates. Generally speaking the second planting dates was the best for all propagation methods.
