Abstract

Shorea platyclados is one of fast-growing Dipterocarp species for enrichment planting in Logged-Over Area (LOA) of tropical rain forests. One of the constrain to supply the seedling for support enrichment planting is the irregular flowering of S. platyclados. Moreover, the vegetative propagation is an alternative method to provide the sustainable seedling for enrichment planting in the LOA. This experiment was carried out to assess the effects of IBA concentrations on rooting ability, the primary and secondary root lengths, and the accumulated number of primary and secondary roots on shoot cutting of S. platyclados. The research was conducted in Completly Randomized Design (CRD) with 5 replications. The treatment was five concentrations of IBA, i.e. 0 ppm, 25 ppm, 50 ppm, 75 ppm, and 100 ppm. The data were analyzed using one-way analysis of variance (one way ANOVA) to determine the effect of IBA concentration variation amongst the treatments. The Duncan Multiple Range Test (DMRT) was used for multiple comparisons among the means of treatment at tα=5%, Results showed IBA concentrations significantly affected the rotting ability, the primary and secondary root length of shoot cutting (P < 0.05). On the other hand, the number of primary and secondary roots was not significantly different among treatment (P > 0.05). For rooting ability, 100 ppm of IBA concentration was the highest of all treatments. Meanwhile, 75 ppm of IBA concentration was the best treatment for development of root, i.e. the number of primary roots, the length primary and secondary roots.

Abstract

Seedling production of S. platyclados through vegetative propagation offers various advantages particularly mass production of good quality seedling in a certain time can be attained. Shoot cutting is affected by various factors including the physical properties of several media on rooting ability and early root development of S. platyclados shoot cuttings. Completely Randomized Design (CRD) was used with 6 replications. Three medium used were Dipterocarp wood sawdust, wood sawdust + rice husk (2/1), and rice husk charcoal. Result showed that wood sawdust bulk density was highest (0.36 kg/l) in compare to that of wood sawdust + rice husk (0.29 kg/l) and rice husk charcoal (0.17 kg/l). The bulk density has positively correlated (r = 0.97) with Water Holding Capacity (WHC) and negatively correlated with porosity (r = -0.99). Rooting ability of the shoot cutting in sawdust + rice husk (2/1) was highest (63%) in compare to that in wood sawdust (43%) and positively correlated with porosity (r=0.59). Early root development in the media did not show significant difference; however, the media of wood sawdust and wood sawdust + rice husk (2/1) tended to have a better early root development compare to rice husk charcoal.
