| Abstract | ||||
| This study determines the effect of some exogenous growth substance treatments on rooting and endogenous growth hormones [the total indole-3acetic acid (IAA), gibberellic acid (GA3), cytokinins (CKs) and abscisic acid (ABA)] in stem cuttings of Casimiroa edulis L. (C. edulis). After 45 days from the treatments, results showed that, no roots were observed in the cuttings without treatment while at 1000 ppm of IBA plus sucrose, BA or pyrogallol is most preferred and more suitable for initiation of roots in cutting. The treatment with IBA 1000 mg/l + sucrose 3% produced the higher number of rooted cuttings (90%) and higher in the average number of roots (6 roots/ cutting). While the cuttings treated with IBA 1000 mg/l + sucrose 5% and IBA 1000 mg/l + pyrogallol 0.5% produced higher average root length (20 mm). Also, there was increasing determined in IAA and CKs levels of cutting treated with IBA (500 and 1000 mg/l alone or plus BA, pyrogallol or sucrose) and decreasing in ABA levels with treatments but the relationship between the rooting and endogenous hormones were uncleared. | ||||
