Abstract:
A study was conducted mainly to determine the effect of auxin on in vitro cultures of
Cryptocoryne ciliata. The growth (fresh and dry weight), reducing sugar, and total
soluble protein were determined after 30 days of treatment. The addition of different
types of auxin with different concentrations induced root formation clifferentially. The
type of auxin used were indole acetic acid (IAA), naphthalene acetic acid (NAA) and
indole butyric acid (IBA). The protein content was low for high levels of concentration of
auxin IAA and IBA (0.6 mg/I and 0.8 mg/I). The reducing sugar content was high without
the presence of benzylaminopurine (BAP) in the medium. The suitable auxin for root
induction was 0.5 mg/I IBA (with BAP) and in the absence of benzylaminopurine (BAP),
the preferred auxin was IAA with 1.0 mg/I concentration.
