  Amorphophallus Chlorophyll missing?
From: Neil Gordon <gneil23 at yahoo.co.uk> on 2010.04.18 at 18:33:53(20868)
Ive got a new batch of Amorph. Titanum seeds on the go, but one of them see
ms to be missing the green bit most plants figure out early in life.

Its had the same light levels as the others, grown in the same place, not t
he biggest and not the smallest, nor the first or last in its batch to open
a leaf.

Its just not going green (like the one behind it which hasnt opened its fir
st leaf properly yet.)

Anyone got any clues, will it die, or will it keep growing in this mutated
colour?

Thanks
Neil

Dear Neil,

If there is no chlorophyll at all in the plant, it will not survive. To
produce the first leaf, it spent all the substances stored in the seed,
but if will not form a tuber because of lack of chlorophyll responsible
for production of all the matter.

If it was partially green (variegated) there would be a chance, just
like a mutation of Spathiphyllum I have.
It grows very slowly, since a few months it is growing in a small
greenhouse made in an empty aquarium and it's becoming stronger.

I append also 2 photos how it looks today.

best,
Marek

I had an albino seedling in a batch of A. bulbifer back in the 1990s. It did not survive much beyond 2" or 3" tall. I presume it was unable to photosynthesize.

Enjoy it while you can. It'll die without chlorophyll once it uses up the e
nergy in the seed.

I guess, it is missing chlorophyll and will die soon, when it eats up all
the food stores from the seed. I had the same with an Amaryllis seedling.

Neil,

Out of curiosity, where did you obtain your seeds? I recently (well a few
months ago) had a single A.titanum seedling do this as well out of a batch
of 5. It didn't seem to produce a tuber during this time for me while the
others did, and I had taken it out of direct sunlight for fear of it getting
burned by the sun. I'm not sure if it had anything to do with it not
producing a tuber, mainly because I'm unsure it could. As far as I had
understood it, these albinos will eventually die (I believe the "Shattered
Glass" A.konjac variant produces a number of albino offsprings that live for
the season, but die without making a tuber). It was just odd as I had never
heard/seen of it occurring with other Amorphophallus species; not to say
that it doesn't happen, just that I personally hadn't heard about it.

The albino A.titanum I had eventually died with barely a recognizable tuber,
but I knew it wasn't going to grow. I don't know if you can feed enough
nutrients through the soil to get it going, but because of how much is
produced by the leaf, I would suspect feeding directly through the roots
won't be of much help.

G'day Neil,

Back in 2005 we purchased 4 Titan seeds - all 4 germinated and two were
pale mutants, same as you have. They (the all-white seedlings) grew for a
while and then just faded away without turning green or forming a tuber....
which is what I expected really. Kind-a hard to make a life with no (or
minimal!) food!

My gut feeling is it doesn't have anything to do with the environment
they're germinated in, I'd say it's a genetic thing...

On a side note, I've just recently weighed in one of the siblings @ 10.34 kg
after 5 years. It's been averaging a 3-fold weight increase with every leaf
cycle (each leaf cycle lasts around 18 months, with a ~2 month dormancy in
between)... so perhaps by 2012 she'll be ready to strut her floriferous
stuff!

Hope that helps,

Jeremy P

Hi Neil,

Your achlorophyllous Amorphophallus titanum seedling is an albino,
commonly occurring in Amorphophallus seedlings, as well as in most
other aroids, due to inbreeding depression. Unfortunately, the
seedling will die once it has depleted the stored food in its seed.
However, it is possible to keep albino plants alive in tissue culture
by heterotrophically providing them with the carbohydrates they
cannot produce themselves via photosynthesis.

Regards, Scott

Its variegated. If it survives it will be worth thousands of dollars.

I refuse to participate in the in the recession.

Mine were an ebay buy, sold in 5 as well, from a company I cant remember th
e name of, in the USA, maybe we bought them from the same batch?
I had 8 seeds in total, all fine except that one.

I kinds suspected it wont survive, but a curiosity while it lasts!
Thanks
Neil
