Effect of plant growth regulators on rooting of henna (Lawsonia inermis L.)

Studies have shown that rooting substrate is one of the effective factors at rooting of hard rhizogenetic plant such as Henna. The purpose of this study is to determine an appropriate concentration of Naphthalene Acetic Acid (NAA), Indole Butyric Acid (IBA) and salicylic acid (SA) on Rooting of Henna. Present study showed that there was a great variation in most of the measured characters at P< 0.05 percent level. The obtained results show that hormonal treatments have caused the increase of percent of rooting. The use of SA caused a positive effect on rooting. The maximum leaf was obtained in 2000 ml.L-1 NAA + 200 ml.L-1 SA. This study shows that Plant Growth Regulators have a profound influence on Rooting of Henna
