Abstract :
Magnolia soulangeana is a big shrub or a small tree with an irregular growth mode and a spring flowering tree whose large flowers appears before the emergence of leaves. Blossoms will be reflowed in early summer. To evaluate the effect of different concentrations of indole butyric acid and the proper time of better rooting for Magnolia soulangeana cuttings, an experiment was conducted in 2013-2014 in Gorgan University of Agricultural Sciences and Natural Resources Research . Five prepared levels of indole butyric acid of zero, 1000, 2000, 4000, 6000 mg L-1 and the bottom of cuttings were put in the above solution for five seconds, and then they were kept under mist system within the context of the greenhouse for 75 d and after that, they were removed for measuring the desired parameters. The highest percentage of rooting, the average number of roots, the average length of roots and establishment percentage related to 4000 mg L-1 attendance was in late June. All traits under study were significant at the level of 1%. Cutting in late June had positive impact for all traits under study, such as rooting percentage, callusing percentage, root number, and root length. After all, the concentration of 4000 mg L-1 of indole butyric acid in which the largest test number and highest percentage of survival can be seen is considered as one of the best hormonal treatments.
