Abstract
An experiment was conducted to investigate the effect of potato extract (PE) on seed germination and seedling
growth of Vanda roxburgii in vitro, a local orchid. Potato extracts significantly enhanced seed germination and
seedling growth. Among the concentrations, PE at 200 mlL-1 enhanced per cent germination from 17.2% (control) to
78.24% and was found to be the most suitable one for seed germination. It was also the best among treatments for
production of viable protocorms as well as healthy seedlings from seeds. Growth of seedlings in respect of length of
shoot, number of root per shoot and length of root per seedling was significantly enhanced in medium supplemented
with 100 mlL-1 of PE. It may be concluded that PE at optimum concentration could be supplemented in medium for
high percentage of seed germination and seedling growth of Vanda orchid.
