Ethylene’s effects on flowering vary between
species, but it has been well established
that ethylene induces flowering in
geophytes (Abeles et al., 1992). The mechanism
by which ethylene stimulates flower
induction in these plants is largely unknown.
It has been proposed that the induction of
flowering may be the result of changes in the
source and sink activities, which lead to increases
in the carbohydrate status of the apex (Sachs, 1977).
