Abstract :The agricultural and medicinal plant pomegranate insert ignore into journalissuearticles values(Punica granatum L. cv. Wonderful); was studied to examine the effects of wounding of cuttings and to test the effects of different concentrations of indole-3-butyric acid insert ignore into journalissuearticles values(IBA);, gibberellic acid insert ignore into journalissuearticles values(GA3);, hydrogen peroxide insert ignore into journalissuearticles values(H2O2);, melatonin insert ignore into journalissuearticles values(MEL);, and ascorbic acid insert ignore into journalissuearticles values(ASC); on rooting of the shoot cuttings under mist. The data indicated that IBA had a positive influence on the rooting percentage in wounded and nonwounded cuttings. The best rooting was achieved with very thin cuttings insert ignore into journalissuearticles values(3-4 mm in diameter);. The percentage of rooting insert ignore into journalissuearticles values(100.0 ± 0.0); and the number of roots per plant insert ignore into journalissuearticles values(15.2 ± 2.4); were positively affected if the point of severing was at an internode of the cutting. It was found that 17 mg L-1 H2O2 in combination with 1000 mg L-1 IBA produced the longest roots, whereas 500 mg L-1 GA3 in combination with the same IBA concentration insert ignore into journalissuearticles values(1000 mg L-1); reduced root length. In addition, the human hormone MEL at an application of 1.16 mg L-1 can be substituted for IBA to produce positive effects on rooting, while 352.24 mg L-1 ASC alone or in combination with IBA also promoted rooting.
