Effect of hormone and its concentrations on root formation:
The effect of basal medium in combination of 2 hormones (NAA and BAP) was studied. As shown in Table 2. The highest root length were observed in 1 mg/l NAA with 0.25 mg/l BAP (4.167 ± 0.15 cm) in the other hand, the lowest root length and the lowest rooting percentage (73 %) is related 1 mg/ l BAP (1.297 ± 0.03 cm), growth rate was shown better in all
