  Propogation of Amorphophallus from Petiole Tissue
From: Don Burns <burns at mobot.mobot.org> on 1999.04.07 at 19:21:07(3244)
We have periodically discussed the propogation of Amorphophallus titanum
(I believe) from leaf tissue. Has anyone tried this with tissue from
petioles of any of the A. species?

Dear Don,

For my DNA-research I have to cut Amorphophallus leaflets . Just for fun I
kept some of these leaflets in water to see how long they will stay green.
Now I have got leaflets of three Amorphophallus species, which are green
since october and have rapidly developed small tubers with roots. I do not
know whether they will survive a transport into soil, for they are still in
water.

Don,

I have tried it on Amorph. galbra and it failed miserably.
Undeterred I have done another batch of galbra and some variablis.
They are looking ok so far and I am hoping my new whizz-bang
heating pad is going to do the trick.

Cheers,
Rob.

Dear Don,
My friend Bobby Mc Gehe here in W.P.B. called me and showed me an
Amorphophallus Sp. that had re-generated after it`s petiole had accidently
broken off cleanly about 1" above the tuber, he had just stuck the petiole
back into his potting medium, and it rooted. It MAY have been A,
albispathus, but I can not be sure. I believe I wrote to 'King
Amorphohallus' Wilbert and reported it at the time, but again can not be
sure! This was several years ago.
Cheers,
Julius

King here!

Yes, Julius story has been repeated here. I also once had a broken leaf
and the petiole regenerated a tuber at the base and is now growing fine.
Mind you, I am sure not all species will do this but the ones with very
turgid petioles will (and now all of you wann know which ones I mean,
huh? Well, figure it out yourselves...... I am not going to demolish all
leaves that are up now.....).

Gijs' story is remarkable but represents the same phenomenon. Stress
apparently can induce tuber generation. Who knows, Gijs, maybe these are
retrotransposons that are activated by stress and do their
thing........(this was just showing-off with terms.......).

Cheers all,
Wilbert
