This study aimed to investigate Four levels of IBA concentration: (0
(control), 1000, 2000, 4000 ppm) and three kinds of rooting media: sand,
peatmoss, sand+sawdust in ratio of 1:1 in a factorial complete random design.
The results indicated that
the concentration of 2000 ppm was superior at
rooting percentage 76%, root number (20 roots) and root length 13 cm over the
other levels of concentration. Besides, the media of (Sand+Sawdust) was
superior at rooting percentage 72%, rooting number (19 roots), root length 11
cm, physical and chemical charactaristics and the charactaristics of the rooted
cuttings.
This study has been conducted to show the influence of some factors to the
rooting of semi-wooden cuttings of boxwood Boxus suffruticosa L. in order to
know the best concentration of indol biotryc acid (IBA) and the best rooting
media for the root
ing of boxwood cuttings .
The experiment was designed in the sub-plots method and semi-wooden
Boxwood cuttings were used. The cuttings were treated with three
concentrations of IBA: 3000, 5000, 10000 p.p.m. using fast dipping. Then the
cuttings were planted (distributed) in five rooting media, namely: sand, peatmoss,
khaffan, (sand+peat-moss) in the rate of (1:1), (khaffan+ perlite) in the
rate of 1:5 respectively. under protected conditions. The experiment has
continued for 8 weeks.
