Abstract

Eha (Castanopsis buruana Miq.) is an endemic and valuable species of the Castanopsis genus which is potential for both producing of wood and also source of food. However, sustainability of C. buruana has many constraints in its growth and development such limited of seeds production due to the plants do not produce seeds every year and low of seeds germination because of hard and thick seeds coat. In order to increase the plant population, it is very important to do species propagation with vegetative propagation methods by stem cuttings. This study aimed to get information about vegetative propagation of C. buruana and to examine the success of vegetative propagation C. buruana using stem cuttings which were influenced by the application of rootone-F. The research was designed by using a completely randomized design consisted of 5 treatments, namely no rootone-F (control), application of rootone F 100 ppm, 200 ppm, 300 ppm and 400 ppm. Each treatment was repeated four times and each replication consisted of 5 plants, so that there were total of 100 plant units. Media used were combination of sand: soil: rice husk charcoal (1: 1: 1 v / v / v). Thus, the variables used to determine the success of C. buruana stem cuttings were live percentage, sprouting percentage, number of leaves, percentage of rooted cuttings, number of roots, length of roots and number of rooted days. The data were analyzed using the F test- if the treatments had a significant effect then it was followed by the Duncan test with the 5% confidence level. The results showed that the application of rootone F had no significant effect on all tested variables. There were no differences between rootone F treatments and control for all observed variables. At the end of the research, the stem cuttings had not produced roots yet. Moreover, C. buruana can be propagated without the addition of rootone F.
