Lucky bamboo (Dracaena sanderiana) canes are naturally straight. Yet they can be encouraged to form spirals by manipulating the plant's position relative to its light source. However, the problem associated with producing value added plants is a longer time taken to produce spirals. Hence the present study was aimed to produce spirals from Dracaena sanderiana stalks within the shortest possible time to make value added products more feasible. The experiment was arranged as a completely randomized design (CRD) with six treatments randomized in three replicates. Treatments were the five different concentrations (ppm) of auxin, i.e., 50, 100, 150, 200, 250 ppm combined with 100 ppm of gibberellic acid (GA3) applied to pot plants and rotated twice a week at the angle of 45°. Application of 100 ppm of gibberellic acid only and rotation (45°) of plant stalks in front of the sun light at twice a week was considered the control of the experiment. In the first experiment, plants taken from 25-cm length cuttings were rotated once a week at the angle of 45°. However, a week after the hormone treatment, spirals rooted and smoothness of canes was reduced. Hence this experiment was arranged to rotate plants with the same angle (45°) twice a week; measurements were taken on spiral growth, plant height, internodal length and smoothness of the spirals. Data obtained were tabulated and analyzed subjected to the analysis of variance (ANOVA) procedure of Statistical Analysis System (SAS). Duncan's new multiple range test (DNMRT) was performed to compare differences among treatment means at p=0.05. Among different treatments tested, the highest length as well as smoothness of the spirals was manifested from plants treated with 50 ppm auxin + 100 ppm GA3. When correlation analysis was performed for overall data, there was a significant (p<0.01) positive correlation between plant height and the spiral length. On the other hand, plants taken from 35 cm cuttings showed a fast growth of spirals than plants taken from 25 cm cuttings. In the light of this situation 100 ppm of GA3 + 50 ppm auxin applied to plants (taken from 35-cm cuttings) and rotated at 45° angle in front of the light can be considered the best treatment to produce value added products from Dracaena canes.
