Oleander (Nerium oleander L.) is cultivated recently as a flowering pot plant and therefore abundant propagation plant material for commercial use is of great importance. Oleander is a vegetatively propagated ornamental plant valued for its evergreen foliage and showy terminal flower clusters that are available in different colours. Studies have shown that rooting, plant growth regulators is one of the effective factors at rooting of hard rhizogenetic plant such as oleander. The purpose of this study is to determine an appropriate concentration of salicylic acid (SA) on rooting of oleander. Present study showed that there was a great variation in most of the measured characters at P
