<![CDATA[Bamboo is one of the potential plants in the Flores area, one of which is in East Flores Regency. Decree of the Governor of East Nusa Tenggara No. 404 of 2018 states that bamboo is designated as one of the 14 leading Non-Timber Forest Product (HHBK) commodities in East Nusa Tenggara. The percentage of survival from multiplication of betung bamboo branch cuttings is still low, namely around 44.44% so that it becomes a problem in procuring seeds. This research was conducted to determine the effectiveness of natural ZPT on the growth of betung bamboo branch cuttings with various concentrations and which concentrations of natural growth regulators gave the best results in the growth of betung bamboo cuttings. The research method used a completely randomized design (CRD) with 1 factor, namely the concentration consisting of Control (Aquades), Shallots and Coconut Water with each concentration of 25%, 50%, 75%, 100%. The results showed that natural PGR of coconut water and shallots had a very significant effect on the parameters of the period of shoot emergence, number of shoots, number of leaves and root length of bamboo betung branch cuttings (Dendrocalamus asper) but had no significant effect on survival percentage of bamboo betung branch cuttings. Treatments A1 (25% concentration of ZPT coconut water) and A5 (25% shallot concentration) gave the best results for the parameters of the shoot emergence period, number of shoots, number of leaves and root length of bamboo betung (Dendrocalamus asper) cuttings.]]>
