Abstract: | Effects of cyclic AMP and traumatic acid on adventitious bud initiation inTorenia stem segments culturedin vitro were examined. Both the compounds stimulated bud initiation at relatively low concentrations. Simultaneous addition of an anticytokinin did not counteract the stimulatory action of the 2 chemicals. Their stimulatory effects were also clear when expiants were pre-incubated for 2 h with 1 μM of either of the 2 substances. The treatment with cyclic AMP and traumatic acid may favourably modify some physiological process which is triggered by excising expiants (wounding) and leads to adventitious bud initiation. |
