Well, there are many Arisaema with completely
stable variegation of course, assuming you will allow all of the silver centered
leaf forms to be included here, which I personally would, but maybe not
others. Michael can comment on the stability of his Amorph, but it seems
less than "stable" from reading his posts.
There are of course many other things that cause
variegation, including some chemicals that are not particularly harmful,
i.e., antibiotics. Some of these characteristics of antibiotics have
even been used to cause readthrough of premature stop codons in human disease in
order to obtain full-length protein as I am sure many on this forum are well
aware. A quick literature search will reveal a host of things that could
be potentially used, although I would never suggest anyone use these things that
does not atelast have some knowledge of fundamental scientific method and takes
appropriate precautions.
Of course, if you were really into this you
could use a gene targeting approach or perhaps you could introduce a transgene
on an inducible promotor, but this is now only in the realm of the true
gene-jocks out there.
best of luck with everyones
experimentation,

Ok, but can we stabilize variegation? Are there any
variegated tuberous or rhizomatous aroids?

Variegation can be induced with nasty mutagens like
Nitrosomethyl urea.
I would not recommend doing so unless you have a
compelling reason and
experience using such chemicals. There are a few
viruses that cause
variegation but most of them harm the plant and make
them useless. The
big exception is some forms of the mallow family
Abutilon.
Micropropagation can induce many variations and some of the
variegated
forms of plants do come from micropropagation but it appears
to be low
frequency so finding them involves a great deal of chance and
or large
commercial production where tens of thousands of plants are
produced and
grown out. Spontaneous mutations of plastids can occur and
are seen in
seedlings on occasion and this is the source of some
variegated plants.
So the answer is not
simple.

Dear All,
Can somebody help me
with variegated Araceae? Because I do not know how
variegation starts.
Are there some viruses or chemicals which can induce
variegation? Can
occure variegation by micropropagation? How often?
The second
question would be: How to take care of Anubias and
Cryptocoryne. They are
sold as aquatic plants, but my Anubias has grown
out from the tank. Do
they need a dry period or what? What are the
requirements of Lysichitons.
I have allready killed 5 pcs.
Sorry for the many questions, but I
still not received the Aroid book,
and thank you for your help in
advance!
