Abstract
As a result of the outbreak of an unidentified disease
among onion plants, these plants were examined quantitatively
for their auxin contents. Both the bulb and the stem were
found to contain detectable levels of Indole-3-acetic acid
(IAA), The stem appeared to have generally a lower level
of IAA than the bulb. The concentration of IAA in twisted
(diseased) onion plant was also determined. Though only
one specimen of the twisted onion was available for the
present work, it is very likely the twisted onion contains
a higher level of IAA than do the healthy ones. This
will have to be further confirmed during the rainy season
when the twisted plants are usually available.
