Abstract:
Pennisetum setaceum ‘Rubrum’ was used as experimental material.The effects of ramet method，different cutting positions and indoleacetic acid (IBA) concentrations on seedling growth and multiplication efficiency were studied by ramification and cuttings，in order to select the optimal breeding conditions for the Pennisetum setaceum ‘Rubrum’ and provide reference for its efficient propagation.The results showed that propagation through cuttings was the most efficient method for Pennisetum setaceum ‘Rubrum’.The quality of seedling growth produced from different parts of Pennisetum setaceum ‘Rubrum’ stem cuttings was in the following order,lower buds>central buds>upper buds.The best growth status of seedlings was observed when treated with 0.3% IBA，and the highest multiplication coefficient was achieved when the lower buds were treated with a 0.3% concentration of IBA.
