ABSTRACT: The sweet taste of Stevia leaves makes it a
potential substitute for table sugar which can be used to sweeten foods and
beverages. However, the limited planting materials become a constrained to
large production; hence
the experiment aims to investigate the different part and methods of
propagation for stevia specifically use of different rooting hormones. The experiment was laid out in 3 × 4 factorial
arranged in
Randomized Complete Block Design. It consists of 3 types of cutting (shoot tips, intermediate
stem and basal stem part) and four kinds of commercial hormones (miracle gro, rootech gel,
NAA and control). Results showed that the highest percentage survival of stevia
was obtained from shoot tips (93.92%) which differed statistically from those
intermediate (91.00%) and basal stem cuttings (85.51%). On the other hand,
basal stem cutting significantly has the lowest percent survival. Results
revealed that shoot tip cuttings treated with Rootech Gel developed roots early
(6.92 days), with most number of roots (13.70), longer roots (3.33 cm), and
96.38% survival.
