Abstract

For many landscape tree species, the production of rooting stock by seeds is not reliable due to difficulty in seed collection and at the same time some tree exhibit seed dormancy. Vegetative propagation by stem cuttings is one of popular alternative used by tree growers. This study was conducted to determine the rooting propensity of two different landscape trees which were Tabebuia pentaphylla and Spathodea campanulata. Three different concentrations of indole-butyric acid (IBA) (0, 100mg/L, 200mg/L, 500mg/L) and commercial rooting powder - SADEX® were applied on stem cuttings of three-year-old T. pentaphylla seedlings and one-year-old coppice shoot of S. campanulata. Another set of cuttings were not treated with IBA (as a Control). Forty cuttings of each species (20 with leaf and 20 without leaf) were used for each treatment and planted in Styrofoam cooler box (500mm x 383mm x 310mm – LxWxD) containing sieved river sand. The cuttings were assessed for their rooting for 14 weeks. The results show that PGR concentration significantly affected the rooting propensity for T. pentaphylla and S. campanulata. Overall rooting success of T. pentaphylla is 16.5% while S. campanulata is 28%. For T. pentaphylla cuttings treated with 100mg/L of IBA (22.5%) and untreated cuttings produced 25% of rooting success while for S. campanulata, 100mg/L of IBA produced 42.5% of rooting success. On number of roots, the overall analysis shows that PGR treatment (P=0.002), species (P=0.003) and interaction between PGR treatment with species (P=0.000) produced significant effect. It could be concluded that S. campanulata is much easier to root species compared to T. pentaphylla.
