Abstract

The first problem that faces fruit trees production
is the limited success of rooted cuttings due to the poor
root formation in cuttings of some species. Moreover, in
some cases, hard wood cuttings are able to get roots at the
first stage, then dry and die either after planting or at
transplanting, due to their poor root formation. Such problems
are observed in hard wood cuttings which are commercially
used in fig propagation, resulting in low rooting
and survival percentages under normal conditions.
In previous study, Mokashi (1978) reported that Thompson
seedless grape cuttings are considered among difficult to
root, and the best rooting percentage was obtained by
soaking Thompson seedless cuttings in IBA at 250 ppm for 12
hours. He explained rooting difficulty by the low content
of sugar, phenolic compounds and C/N ratio.
It is well known that a mixture of more than one growth
regulator has been used to improve rooting ability. produce
more roots and to increase rooting and survival percentages.
These growth regulators such as Indole 3-acetic acid (IAA),
Naphthalene acetic,acid (NAA) and Indole-3-butyric acid (IBA)
