Appeal No. 94-1942
Application 07/773,603
11. A process for producing tubers from a tuber-forming
plant belonging to the genus Solanum comprising the steps of:
(a) culturing a plant piece having at least one bud in a
culture vessel containing a liquid medium comprising:
i) a carbon source and
ii) inorganic salts;
(b) exposing said plant piece of step (a) to alternating
periods of light and dark while the plant piece contacts the
medium;
(c) exposing said plant piece to carbon dioxide during at
least one light period of step (b) to induce and propagate
shoots and stolons from said plant piece;
(d) culturing said stolons of step (c) in a liquid medium
containing a carbon source; and
(e) exposing at least a portion of said stolons to a
gaseous phase during step (d) under conditions sufficient to
induce the formation of tubers on said stolons.
