| Summary: | Neolamarckia cadamba or kelampayan is well known throughout the timber industry due to
its fast growth rate. Kelampayan has many end uses that are not just limited to the timber
industry. Through in vitro micropropagation, arise new ideas of producing new variation of
white kelampayan. This study was attempted to develop new clones with improved traits of
white kelampayan through in vitro mutagenesis using Ethyl methanesulfonate (EMS). In this
study, calli and nodal segments were treated with three different concentrations of EMS, i. e.
0% (control), 0.1 %, 0.3% and 0.6% (v/v). Calli were exposed to EMS for 0.5,1 and 24 hours
while nodal segments were exposed for 3 and 6 hours. Effects of EMS toward calli and nodes
of kelampayan were identified in this study. For the calli, as the concentration and exposure
duration increases, the percentage of survival and proliferation trended to decrease.
Meanwhile for nodes, similar trend was observed on the survival percentage, number of
leaves and plant height. Potential mutant cultivars with irregular leaves, red coloured leaves
and early branching were also observed. It is recommended to do further studies on these
potential mutants cultivars at genetic level by using DNA marker. |
