This study was conducted in a plastic house at the Department of Horticulture
and Landscape Design, Faculty of Agriculture and Forestry, Mosul University,
In tow dates (15th November and 15th February) during 2019/2020 season, in
order to study the effect of the date of sowing and treatment with Indole Acid at
concentrations of (0, 250, 500, 750, 1000 and 2000 mg/L), and the effect of the
interaction between them on root ability of the half woody cuttings of
Dodonaea viscosa plants, and the extent of its effect on improving the
characteristics of root and plant growth. The experiment was laid according to
completely randomized design CRD with two factors and 3 replicates per
treatment, and ten cuttings per replicate. The data was statistically analyzed and
its treatments were compared with Duncan multiple test. The results showed
that the date of getting the cuttings and treatment with Indole acid had a
significant impact on the studied traits. No rooting was observed at the first
date, while the second date had a clear response after ten weeks of cultivation,
where the highest rooting percentage was obtained (33.33 %) due to the
treatment with a concentration of 1000 mg/L and the number of roots (14.43)
and the highest value of root length (10.86 cm) and the number of vegetative
branches (1.96) and the length of the vegetative branch (2.76 cm) besides the
fresh weight of the roots (2.50 g) and the highest dry weight (0.08 g)
