Abstract:
The developing floriculture industry seeks
domestic pot ornamental plants as it is not further
being luxury in effort. Several endemic flowering
plants have the potential to introduce as pot
ornamental. But creeping growth attributes of this
endemic plants should be tested with growth retardants
and physical manipulations before introduce those
plants into the floriculture market. A shade house
factorial experiment was arranged in eight treatment
combinations of pinching/non-pinching and various
Paclobutrazol concentrations (0 ppm, 15 ppm, 30 ppm
and 60 ppm) with eight replicates for each treatment.
Paclobutrazol was applied in twice, two weeks intervals
while, soil drenching and pinching was done. Results of
the experiment disclosed that the plants showed better
performances in growth retardation and other
characters measured with the pinching and
Paclobutrazol concentrations increasing, but degree of
leaf deformation was increased when increase the
concentration of Paclobutrazol. It was observed that 15
ppm Paclobutrazol applied plants showed balanced
growth retardation and acceptable plant characters.
Application of Paclobutrazol in concentration of 15
ppm along with pinching caused considerable
suppression of height that makes increased
floricultural value for the Henckelia plants.
