The Effect of Different Treatments of Indole-3-Butyric Acid (IBA) on Rooting of Clerodendron Phlomidis

The research has been done for assessment of effects of different concentrations of Indole-3-Butyric Acid (IBA) on rhizogenesis of scions of C. Phlomidis in 2010.  The research has been done on Randomized Complete-blocks for five replications and three treatments with zero, 2000ppm and 3000pmm concentration. Different characters such as number of root of each scion, length of root, length of new branches, thickness of root, number of leaf, dried weight of root and dried weight of leaf have been evaluated in this experiment. The results revealed that there is not any significant difference between hormones treatments but there are significant differences with zero treatment. Therefore, treatments with zero concentration have the least rate at all assessment characters.  Between two hormones treatments the most number of root of each scion and the length of the highest branches in 2000pmm and the length of the highest root, average of length of root, number of leaf of each scion, dried weight of leaf in 3000pmm have been seen. Therefore, 2000ppm concentration of Indole-3-Butyric Acid is suggested as the most desirable concentration for rhizogenesis of scions of C. Phlomidis.
