Abstract

The purpose of this study is to investigate the effect of four concentration of auxin (IBA) ( 0 , 3000 , 5000 , 8000 p.p.m ) and kinds of different mediums ( sand + peatmoss ) ( sand + poultry manure ) (2:1) , sand + poultry manure + peatmoss (1:1:1).
An improvement of rooting percentage and all rooting and vegetative growth of Henna plant Lawsonia inermis L., The experiments was designed in two stages , The first stage designed in C.R.D with three replicates and 15 cutting of each treatment , The second stage of experiment was arranged in factorial (2-factors) experiment in complete randomized design (C.R.D) were used with 3-replicates and 5 cuttings of each treatment .
Treatment were compared using least significant test (L.S.D 0.05) at 0.05 , The most important results showed that using of IBA in all concentrations of auxin was significant increase gave in all rooting traits for the treatment cuttings comparing with untreatment cuttings (control) All auxins concentrations significantly in creased all cuttings parameters in comparisons with untreated cuttings . except treatment T2 in Rooting length . Also T4 (4000 p.p.m IBA) the highest rooting percentage (86.71%) and number and length of Roots which that (23.83 and 8.07 cm) respectively . Results for the two stage of the experiment are summarized follows :
The results showed that the effects of medium culture M3 (sand + peatmoss + poultry manure ) (1:1:1) was significantly increased in most parameters (content chlorophyll relative , number of leaves , number of shoots plant , leaf area ) which that ( 41.78 spad unit , 98.8 , 7.25 and 10.52 cm2 ) respectively .
All IBA treatment caused a significant increase for all vegetative growth compared with control specially treatment T4 comparison of means also showed that interaction of medium culture and concentration of IBA had significant effect on highest content chlorophyll relative , number of leaves , number of shoots , leaf area and high of plant were observed on T4M3 (sand + peatmoss + poultry manure ) × 8000 p.p.m IBA .
