Dracontium gigas - Brutknolle - was nun?

Hello everyone

Since about 1 year, I have a small (diameter approx. 0.8-1 cm) Dracontium breed Knolle lie in the substrate. Last winter, hot and slightly humid in the living room and the summer outside. Unfortunately without the leaves were trained.

While cleaning up, I have times carefully aside substrate and discovered something like this like a small shoot on the tubers. Roots are however not visible...

What do I do now to best? I have now just so much substrate accumulated again, that the tip of the shoot sees light in the hope that this will stimulate the growth.
Do you have more tips?


Greeting
Marco

Hi Marco,.

Make polyphyllum Dracontium gigas and also D. very many small Cormels or nodules, which sit on the mother tuber, but not cast out.
Probably a Übelebensversicherung, if the mother tuber.

But even if one separates the brood nodules, it takes usually a long time until you expel if she make's bipartite...

If your speeding tickets has been a white tip, but great – I would completely cover them and let things run their course; I don't know whether it is conducive to sticking out the top.

Happy growing, Bernhard.

Hi Marco,.

as Bernhard has described it I would do it. If the roots like in Amorphophallus above the tuber to grow, then you need Yes also place in the substrate while the tip is not green light won't...

Love greetings
Michael

index.php? page = attachment & attachmentID = 3690

Continued by transplanting a 13 months now until the visible drive...

Thank you for your help. Let's see how I'll keep this thing alive and growing.
Just in short supply is warm and bright. Or is bright not so important?

Hi Marco,.

Yes, it's true – some of us love types you must be soooo patient.
4 1/2 years at a cicatricifer bulb, which I received in July 2011 and which were the longest time, I once waited until spring 2016 (!) driven out is...

I'm glad that your D. gigas grows now :-)
Hell would be important, but if you can offer any additional exposure, or, even without going to; the shortest day of the year is soon reached.

Happy growing, Bernhard.

... Yes, patience is already required, by germinating the seeds, which can take long until the first flowering; but this is also the appeal.

Hello everyone
the first sheet has endured until March of this year and was replaced seamlessly by sheet No. 2 in April.

This is now about 30 cm high.
index.php? page = attachment & attachmentID = 4941 index.php? page = attachment & attachmentID = 4942

The petiole looks great!
index.php? page = attachment & attachmentID = 4943

I read somewhere that the drawing / structure of the Petiolen in Amorphophallus Lichen or cyanobacteria (mimicry) to play and should therefore suggest inedible, lignified shoots.

Do you know anything about it?

Hi Marco,.
Mimicry sounds good comprehensible, if you also conclusively proves that I don't know, it will be too hard.
In any case, the a real hot petiole is! I've never seen.

Hello Marco,

a very detailed article has just been published:

https://academic.oup.com/botlinnean/adva... edFrom=fulltext

However, it is not yet published ( https://doi.org/10.1093/botlinnean/boz014 ), but only available online e.g. at the University Library Hannover; also via other university libraries that have the journal available; should have all universities with fields of biology or botany.

I haven't read the artkel yet, I've just flown over; Worth seeing are the pictures alone...

Happy growing, Bernhard.

P.S.: also yes, the online access at the UIni-Bilbliotheken is of course usually only available for students or university/institute employees.....
