| Summary: | This study was to determine the effects of different plant growth regulators
(PGRs) on breaking of dormancy and induction of multiple shoot formation
from rhizomes of Curcuma cordata. This study comprised of four
experiments. The first experiment was conducted to evaluate the effect of
different PGRs at various concentrations on breaking of dormancy of
rhizomes of C. cordata. The PGRs used were IBA (0, 250, 500 and 750
mgL -1), GA3 (0, 500, 1000 and 1500 mgL -1), SAP (0, 100, 200 and 300
mge1), ethephon (0,250,500 and 750 mgL-1) and daminozide (0,500,1000
and 1500 mgL-1). The second experiment analyzed the influence of light
intensity and 6-benzylaminopurine (BAP) on breaking of dormancy of C.
cordata. The light intensities were: 18 molm-2s-1, 9.3 molm-2s-1, 4.4
molm-2s-1, 2.4molm-2s-1, 1m01m-2s-1 and 0 molm-2s-1, respectively. The
third experiment analyzed the effect of different PGRs with sucrose at various
concentrations on breaking of dormancy of rhizomes of C. cordata. |
