Improvement of rooting of semi-hardwood cuttings in Henna (Lawsonia inermis L.) to plant growth regulators

This studying have used to determine suitable concentration NAA , IBA and SA for destroying root half hard of henna . This experiment performed in one planning completely accidental in for repetition and 15 percent treatment . In this research growth regulator have applied for IAA in a level 2000 mg/lit, NAA regulator in three level 2000, 3000, 4000 mg/lit and SA in two level 200 , 400 mg/lit. Due to achived resolutions show that harmonica treatment have been caused to increase percent of cuttings and statistically difference between treatments Growth regulator showed meaning discrepancy as to example of level 5%. Although the highest percent destroying root cuttings was related to treatment 2000 mg/lit IBA and 3000 mg/lit NAA ,but the highest some of stem in treatment was 4000 mg/lit NAA+200 mg/lit SA and 2000 mg/lit IBA+200 SA and discrepancy of average these treatments didn’t observe with meaning difference in level 5%. Resolutions of this experiment showed that applied treatments have been caused to increase some of root in each cutting . Treatment 4000 mg/lit+200 mg/lit SA have been made the highest weigh of root and stem and weigh of drying root and stem
