UJICOBA MEDIA AKAR DAN ZAT PENGATUR TUMBUH PADA STEK PUCUK TANAMAN GYRINOPS VERSTEEGII

Abstract

The variety of agarwood production in the Gyrinops versteegii plant is one of the main problems in the agarwood cultivation. Efforts to reduce the variation is by cultivating high agarwood production through vegetative propagation, thus the results of the agarwood are expected to be more consistent. Shoot cuttings are the most inexpensive and easy vegetative propagation, however some studies showed a low success propagation rate especially for Gyrinops versteegii. Several factors determine the succed of shoot cuttings propagation i.e: media of rooting and hormon application. Therefore, research to improve the success of G. versteegii shoot cuttings should be conducted.. Based on those issues, the research aimed to determine the influence of the rooting media and hormone on the shoot cutting of Gyrinops verteegii. This study used a randomized complete block design (RCBD) with six media treatments they are soils, soil+compost (3:1), cocopeat+sand (1:1), cocopeat+sand+ compost (1:1:2), soil+cocopeat+sand (2:1:1), and soil+cocopeat+sand+compost (5:3:3:4). IBA and NAA hormones with a concentration of 100 ppm, 200 ppm, 300 ppm and 0 ppm (control) were used in this study. The results showed that the success of shoot cuttings was influenced by the media and hormones; where the best rooting found on the shoot cuttings using soil as media and 200 ppm IBA.
