Abstract. Dendrocalamus asper is a type of bamboo with a large diameter and strong fiber, so it has many benefits for the socio-cultural life of the community, especially in Tana Toraja. However, the extensive utilization has resulted in Dendrocalamus asper decreasing and has not yet been accompanied by adequate cultivation efforts. In order to provide Dendrocalamus asper, a cultivation step is needed starting from providing quality bamboo stumps. The provision of quality bamboo stumps is currently constrained due to the difficulty of growing bamboo stumps in nurseries. Therefore, a study is needed to obtain bamboo stumps that are able to grow fast and in accordance with environmental conditions. The aim of this study was to determine variations in the growth of the Dendrocalamus asper stump originating from several regions according to the height and plant growth regulators (PGRs). This study used a factorial design which was analyzed using an analysis of variance. The bamboo stump was taken from 3 locations namely from Enrekang Regency (<800 musl), Tana Toraja Regency (800-1000 musl), and North Toraja Regency (>1000 musl) with PGRs dose treatment. The parameters observed were growth percentage, shoots speed, number of shoots, and shoot length. The results showed that the interaction between the origin of the bamboo broodstock and PGRs dosage had no effect on the observed parameters. The source of the stumps affects the speed of sprouting. At the same time, the PGRs dosage affects the number of shoots. The growth percentage and stump shoot length were not affected by the origin of the bamboo stumps, PGRs dosage, or the interaction between the two. Information regarding variations in the vegetative growth of bamboo stump is expected to be input in meeting the needs of Dendrocalamus asper and as a recommendation for further nursery activities.
