Hi,.

I have this year by t. venosum "Indian giant" get cuttings root (approximately 1,5 cm), who already had the first sheet in may in the greenhouse above. Now they are each partly during the 12 sheets, larger than the previous.

But my normal venosum, until late June / early July have driven out at me, are partly at the 5th sheet. That seems very strong to be subject to the conditions, which in the flower bed (at the same time driven out) has only 1 sheet. Large pots, full sun, and very much fertiliser help anyway.

I unfortunately don't have images of the natural sites, but I am convinced that they can reach their full size in Germany. It must be just a bit of trouble...

Hi Philip,.

two images would interest me...;-)

And "Indian giant' compared to the normal form."
I had from the 'Indian giant' of a Araceenfan to get United States and think that this is the clone, the plant delights has expelled once.
I don't have the normal form, so that I could also never safely say what I have there. Though, I think that I have certainly 'Indian Giant' because of the American friends of the plant is very nice and is certainly reliable and trustworthy....

@ Dan,

a Komensationsreaktion on the lower radiation - more assimilation area to compensate is that plants in the shade make larger leaves....

My 'Indian giant' are on the South side of the House in the blazing sun (so it seems).
As of midday the leaves roll up however, what probably is a protective reaction against excessive evaporation when insufficient water transport from the roots produced; You can see similar in winter with frost on rhododendron.

A half ramosa site would be so eventulel better.
Ultimately I would wait but, what "rear comes out (in order to talk with former Chancellor Kohl)"; as the thickest tubers grow after culture in the blazing sun, I would expect even the Einsrtrahlungssreß the plants...

Bernhard.

Hi,.

Sorry, you have to to images you have a small little wait. The plants were namely at my workplace in a very hot greenhouse, and when the first Burns showed I taken them home and erected outside. Since they've then by bad weather and spider mites (I know unusual combination:??:) the most leaves lost and now no longer particularly good look. But thanks to the chemical Club they are now back on the road to recovery, I will photograph them once again beautiful leaves there are.
By the way, never more than five hands were well-maintained at a plant, it always which have died if new formed. I was just too lazy to remove the dead leaves, therefore I could count how many have already made the plants.

@ Bernhard: honestly, I am now a bit skeptical about whether we really have the genuine Indian giant. My plants become larger, the more they look like the normal t. venosum. Here a photo of Ken Moshers Indian giant:

The Petiolen are much more closely speckled on my plants.

Hi Philip,.

I will ask once again for specialised in the exchange partner of the United States whether he knows reliable that he had 'Indian Giant' and has.

I had before a few days visit by Daniel an amorphophallus "addicted" collectors who held my plant for 'Indian Giant'; in the normal form, the leaf segments are not as wide.

Perhaps there are still other Forum members, who have both forms (and photos)....

MfG,
Bernhard.

Hallo Dan,

na ja, das mit der Kompensation denke ich mir halt nur.....

Ich stelle meine 'Indian Giant' nun lieber in den Halbschatten, die Blätter sehen nun doch zu mitgenommen aus.

@Philipp: Ich habe bei meinem Tauschpartner in den USA nachgefragt und bestätigt bekommen, daß er den Klon wohl tatsächlich bei Palnt Delights bestellt hat.
Zitat:
"If I recall correctly, I did indeed get that clone from Plant Delights years ago. At first glance it resembles the ?normal? form, especially in juveniles, but the mature plant is quite distinct. The ?Indian Giant? produces leaves that are substantially larger than normal, and the individual leaf segments ( the ?fingers?) are broad, wide, and slightly wavy on the edges. If a normal leaf looks like a giant human ?hand?, with long thin fingers, the Indian Giant leaf looks like a gecko foot, with wide fingers. I hope that makes sense!?
Also, the Indian Giant corm gets much larger, makes fewer offsets, and the bloom is taller and stockier than the normal."
Zitat Ende.

nochmal @ Dan: Woher kommt Deine Info, daß nubicum und 'Indian Giant' eventuell Synonyme sind? Oder habe ich da was falsch verstanden? :???:

MfG,
Bernhard.

Hi Erwin-;-),.

do you have a digital camera???

MfG,
Bernhard.

Hi,.

in the meantime, my doubts are defeated, I am now sure that I have the "real" Indian giant and thus no crap was filmed at the Bernard;-)
My plants characteristic have emerged in the meantime very clearly, there are obvious differences from the normal t. venosum.

@ Bernhard: do you have now already the normal form? If not send I you like some tubers to, in a few weeks I will have more than enough...

MfG Philipp

Hello Thyphonium fans,.

Please find attached two pictures of my 'Indian giant'....

The print shows attributed to the 'Indian giant' properties of the "broad fingers" and of little speckled petiole.

The tuber of an already confiscated plant filled almost entirely from the 3-liter pot:-)

@ Phillip: no, the normal form I don't; have Therefore, I could not describe the differences or judge.

I've got some answers in the aroid L aimed on it that t. is venosum halt highly variable and there are just very large genotypes.
A possible explanation is that the major genotypes are polyploid so vervielfachte chromosome sets have, which then leads to the 'giant 'growth (Kern-plasma-relation would be I think the key word to....).

Further, it is conceivable that nubicum "a great polyploid clone or tribe of t." will is venosum T.. (To nubicum were unfortunately no comments in the aroid L.)

@ Erwin: you have done a comparative photo???

MfG,
Bernhard.

Yes, I have presented in the Forum.

Hi Erwin,.

and already on the 25.08.....
Sorry, that was me account for, but your pictures show actually very nice the difference.

@ Phillip: Wow, that's Yes really great!
How big was the Kolle at transplanting because?????

@ all: I am curious, how big the tubers from my larger pots are, and how the ' Indian Giants' and nubicum Forum members to make in the next year...

Good growing
Bernhard.

P.S.: Here is a picture of Brian Williams' 'Indian Giant' - in the background, still the canonical form....
I have a feeling that something else is this clone jadoch strong....

Next came from Tony Avent (plant delights nursery) that 'Indian Giant' is not a clone, but a trunk, i.e. a population of phenotypically uniform plants, the generative was increased. PDN has crossing the descendant with the normal form. If you then prove in the future as sterile that would be a proof that 'Indian Giant' probably a polyploid from t. is venosum.

Hi Bernard,.

the bulb had only 4.5 cm in diameter, was nothing special really. Shortly after the pot in a 10 liter pot (!), it has flourished and started almost simultaneously with the first sheet that was about 25 cm in length. A regular fertilization has led finally to the pictured leaves with a diameter of 60 cm, am looking forward very on the tuber. This year I've venosum planted for the first time Typhonium and am very positively surprised by the rapid growth. I could already reap a tuber which had 2.5 cm in the spring, now it has over 5 cm diameter and many offshoot. You may look you post in a few weeks so I;-)!

Wow, Brian's plants be surprised again and again, really impressive! I do not think that this is anything other than Indian giant, it will be simply easy to a very unusual clone.
Not surprised that the Indian giant are different clones in circulation, it is yes no selection breeding but a natural shape (see t. nubicum-tread). But it can be so variable I had not thought...

I'm curious about whether we can see a polyploidy. But then some issues would arise:
Polyploid mutants are rarely independent populations, they are present rather scattered in the holdings of "normal" plants of the same kind (I know this behavior at least by a number of other plant species). But it seems obvious from the Indian giant to give closed stocks on the without, otherwise she would be been described sure (t. nubicum) as a separate species. That would rather argue against a polyploidy. Now you should still know why she has lost its status as separate species, could this be related again with the polyploidy or not. So a little bit complicated the issue, rather times wait what the folks at PDN figure out:??:.
