Abstract: The effect of Naphthalenacetic acid (NAA), Pseudomonas putida and Trichoderma harzianum on the rooting response of Clerodendron inerme, Bougainvillea spectabilis and Nerium oleander was studied. The data indicated that the percentage of rooted cuttings was affected by the different treatments and the different plant types. NAAy'P, putida and T. harzianum increased the percentage of rooting of C. inerme, B. spectabilis and N. oleander. Although all treatments inr:reased the rootings of all tested plants, P. putida showed significant increase over other treatments with cuttings of B. spectabilis. The number of leaves of B. spectabilis was increased as a result of NAA, P. putida and T. harzianum treatments. However, the number of C. inerme leaves was increased with NAA and T. harzianum treatments. In contrast, the number of leaves of N. oleander was not affected by any of the studied treatments. No significant differences were detected in leaves dry weight of the treated plants. The length of branches of B. spectabilis was encouraged with NAA, P. putida and T. harzianum treatments. However, only P. putida increased the length of N. oleander branches. The root length of the treated C. inerme with NAA, P. putida and T. harzianum was increased. The root dry weight of C. inerme was increased with NAA and P. putida treatments, whereas, no increase in both of root length and dry weight of B. spectabilis and N. oleander was observed.
