Abstract
Shoot tip explants of Exacum travancoricum, an endangered herb mainly known
for ornamental purpose grown on MS with 4.44 μM BAP and 1.34 μM NAA
showed better growth response and produced 29.3 ± 0.3 shoots per explant with
an average length of 4.6 ± 0.1 cm after 35 days. Roots were induced after transfer
to half strength of MS supplemented with 2.46 μM IBA produced 4.8 ± 0.62 roots
with an average height of 3.6 ± 0.10 cm after 30 days. The rooted plantlets were
transferred for hardening, 80 per cent of plantlets survived and resumed growth
in the mixture of soil, vermiculite and farm yard manure (1 : 1 : 1).
