| Title : | SHOOTS CUTTINGS PROPAGATION OF ENDANGERED AND ENDEMIC TREE SPECIES Kalappia celebica Kosterm USING THE APPLICATION OF ROOTONE |
| Abstract : | Kalappia celebica Kosterm is a member of the Fabaceae family and is included as monotypic species. The tree is one of the most important timber because has a high quality of wood, with dark brown color, making K. celebica has great performance thus increasing its economic value. However, its population has decreased with the increase in logging and wood harvesting, mining, and housing. Natural regeneration is also limited due to infrequent flowering periods and fruiting. Therefore, to improve plant material for replanting, it is crucial to do vegetative propagation, such as cutting and accelerating their rooting and growth using a growth regulator. This study aimed to determine the effect of rootone-f as a plant growth regulator on the rooting and growth of K. celebica cuttings. The study was designed using a randomized block design which consisted of 4 (four) treatments. The treatments used were untreated cuttings (control), application of 100 ppm, 200 ppm, and 300 ppm/rootone-f solution. The data recorded were analyzed using an analysis of variance (ANOVA). The results showed that the application of rootone-f treatments had a significant effect. There is a different response between untreated and treated cuttings. The treatment of rootone f produced better rooting and growth than untreated ones. There was a significant increase in the total of primary and secondary roots, length of roots, shoots number, leaf area, shoots dry weight, and roots dry weight of K. celebica cuttings at eight weeks after planting. The highest rooting and growth were reached by 200-300 ppm treatment. Rootone f application with concentrations of 200 ppm is the optimal dose that could be considered to produce high-quality seedlings of K. celebica from cuttings. The success of shoots cutting propagation for K. celebica will provide primary practice of K. celebica cultivation, support juvenile stage bypass, and contribute to conservation efforts for valuable, endemic, and threatened tree species. |
