ABSTRACT: Stenting is a vegetative
propagation method, based on cutting and grafting in one action. The question
addressed in this study is whether indole-3-butyric acid (IBA) concentration is
able to impress success of Chinese hibiscus propagation when grafted onto two
kinds of rootstocks. The used IBA concentrations include: 0, 1000, 3000 and
5000 ppm and two cultivars of Hibiscus syriacus (“Blue Stain” and “Jeanne
d’Arc”), which have been used as rootstock. Results indicated that, all the
cultivars were superior for most of the measured parameters when IBA treatments
were used compared to control
plants except for average of the longest root size. The highest healing percentage
resulted in stentlings (plant which has been propagated by stenting method) with 5000 ppm
of IBA treatment. All IBA treatments significantly increased rooting percentage
compared with the control plants. Stentlings that were treated with 3000 and
5000 ppm of IBA, produced the greatest leave number. In Chinese hibiscus/“Jeanne d’Arc” combination, higher root
number and dry weight of roots were observed. Interactions of kinds of
rootstock and IBA concentration showed that the highest healing percentage was
obtained in “Blue Stain” in concentration of 5000 ppm and the highest root
number were seen in stentlings with “Jeanne d’Arc” in 3000 ppm and “Jeanne d’Arc”
in 5000 ppm.
