Hello Vincent et al,
Yes, tubers and rhizomes are forms of stems not
roots.
People often talking about Amorphophallus
say "stem pattern". This is not a stem, but a petiole.
The green bodies of Lemnoideae are also modified
stems - these plants have no leaves.
And everybody knows that a spathe is not a "petal"
or "flower", it is a leaf.
Well, we are interested in the most strange plant
family, and we're proud of this :)

You are most probably correct about those plants being
treated with ga3. As I was mention ing to another group member the plant
may look nice and have flowers which is good for sales but at the end of
the season, you will be left with a tiny tuber or no tuber at all. Which
is also good for sales because your plant dies then you go buy another.
Some information I was reading said that Zantedeschia bloom well with GA3. But I would think
they would die at the end of the season or very soo as has been your
experience :-)
Thanks for telling me that a tuber is a form of a
stem. I did not know that. And that may be part of the reason why ga3
can damage them. GA3 will cause main stems in plants to grow very tall.
Obviously a tuber trying to grow tall will not work. Ive got no proof of
this but the reasoning sounds sound to me.
I refuse
to participate in the in the
recession.

Hello,
Now I think I know why all
Zantedeschia plants bought in pots in florist shops with many
inflorescences died shortly after blooming.
These pot plants must have been treated
with GA3, they had more inflorescences than leaves, just to be a
decoration for a few weeks.
They had a lot of flowers, but no tubers,
when the overground parts withered there was nothing in
the pots except the peat.
Zantedeschias I buy as garden plants
with huge tubers behave differently.
They produce one or a few
inflorescences during summer and their tubers grow and
divide.
Thanks for this info, I haven't known
this
Marek
P.S. A tuber is not a form of a root, but
a form of stem (corm).

Use caution with this if you care to
experiment. GA3 retards root growth and will kill your
tubers/rhizomes if it comes in contact with them. Do not use
on amorphophallus unless its a variety that can grow a leaf
and an inflorescence at the same time but dot expect much
tuber growth as GA3 retards that also because is a form of a
root.
I've been using plant growth hormones for years.
If you want to noticeably increase tuber growth then wait
until the tuber has formed a leaf and the leaf is fully open
and established. Then pour a 100-150ppm solution at the base
of the plant avoiding the leaf,a higher ppm is not better, it
will cause the plant to do different things. Just do this one
time during the season and apply high phosphate or bone meal
fertilizer. Keep in a hot and humid shaded greenhouse
for optimal results. Using this method, I made a 2lb konjac
grow into a 7lb monster in one season. The next year it gave
me a perfect flower of specimen quality. Which Ive
posted pictures of here in the past.
This year Im doing
this too all my tubers

Dear Steve,
Yes gibberellic acid has been "intensively" used to
induce the production of an inflorescence with aroid. See
all the work of henny and collaborators.
I wanted to
try but never have time, so please keep me
informed.
Here is the list of some papers by
Henny:

Gibberellic acid (GA3) induces flowering in
Dieffenbachia maculata 'Perfection'. HortScience
15(5): 613. species.

J. 1981. Promotion of flowering in Spathiphyllum
'Mauna Loa' with Gibberellic Acid. HortScience

flowering in Aglaonema with gibberellic acid (GA3).
