EFFECTIVENESS OF CONCENTRATION OF GROWTH REGULATORY SUBSTANCES ON THE GROWTH OF KALIANDRA (Calliandra callothyrsus) TRUNK
Get PDFThe potential of our energy sources in Indonesia is getting thinner day by day. Energy sources that come from fossils if we take it continuously will run out and cannot be renewed. Therefore, it is necessary to have an alternative source of renewable energy, one of the renewable energies to replace fossil energy, is wood biomass. One of the woods that can be used as a renewable energy source is Kaliandra wood (Calliandra calothyrsus). Calliandra (Calliandra callothyrsus) is a type of tree that can grow throughout the year. The problem faced in generative breeding of Kaliandra is the low seed germination caused by Kaliandra seeds having hard seed dormancy, and the skin has a waxy coating. To overcome the problem of meeting the needs of Kaliandra wood in energy resources, vegetative propagation of plants is needed, one of which is stem cuttings. This study aims to determine the level of effectiveness of the successful growth of Kaliandra stem cuttings using various concentrations of growth regulator Rootone F. The research method used is quantitative by conducting various experiments, namely treatment of Kaliandra stem cuttings without treatment, treatment using Rootone-f hormone with concentration (100 ppm), and treatment using the hormone Rootone-f with a concentration (200 ppm). The results showed that the number of shoots and the number of leaves were the same in each treatment, namely 1 shoot. The length of shoots in the Rootone F hormone treatment with a concentration of 100 (ppm), produced the largest shoot length of 0.71 cm, the percentage of life in the Rootone F hormone treatment with a concentration of 100 ( ppm) was 6.67%, and the root length of Kaliandra cuttings on Rootone F hormone treatment with a concentration of 100 (ppm) produced the largest 0.25 cm.
