- Abstract
Porang is known as an alternative food source. The main obstacle for porang production is the long harvest period with growth time needed ranging between 4-5 months and 7-8 months of dormancy. The application of plant growth regulators (PGR) such as CPPU and GA3 could be used to break porang’s dormancy. This study aimed to determine the effect of the application of CPPU and GA3 on the growth of porang plants from bulbil. Best CPPU and GA3 concentration were determined to be 60 ppm and 100 ppm, respectively. The PGRs were used to treat the bulbils by soaking them for 15 minutes. The bulbils then planted on planting media containing soil:husk charcoal:compost (1:1:1) for 1 month. After 1 week of PGR treatment, the bulbils showed an increase in the number of shoots, bulbil diameter, and bulbil weight when compared to the control. Then after two weeks of PGR treatment, an increase in shoot length, root length, and the number of roots only occurred in the GA3 treatment while CPPU treatment showed different response. At 1 month of PGR application, all treatments showed a lower result in plant height, number of leaf, leaf area, and stem diameter when compared to control. This study showed that while CPPU and GA3 are able to induce shoot propagation, it negatively affected the development of the organs such as roots, stem, and leaves.
