Abstract
ABSTRACT A factorial experiment was conducted in the lath house to investigate the effect of cutting type (terminal, sub-terminal) dates of planting (1/5, 1/6, 1/7/2013) and different concentrations of IBA (0,500,1000,2000 mg/L) and thier interaction on the rooting of cuttings, vegetative growth of Damas plant during summer season / 2013 under the plastic cover using RCBD design with three replicates. Results showed that the terminal cuttings surpassed on the sub-terminal cuttings significantly in all properties studied, as it the first date and the second date of planting were Superior to the third date , and the concentration of 500 and 1000 mg IBA/liter superior on control treatment. The highest average of rooting percentage of cuttings, root number, branches and leaves number are realized at the interaction of terminal cuttings X500 mg IBA/L X date of 1/6/2013 amounted to 100 %, 23.50 root , 15.32 cm, 7.25 branch and 25.25 leaf respectively, while the sub-terminal cuttings at the same date and without auxin gave the lowest average of these properties .
