  abnormal flowers
From: Claire Piette claire.piette at rug.ac.be> on 2000.03.29 at 14:53:44(4272)
Hello,

Recently we found some abnormal Spathiphyllum flowers in our greenhouse.
Some are smaller then usually; others have a normal size, but lack a
spathe and instead there is a little of white amorph tissue. The same
plant has normal and abnormal flowers. The only thing that we changed
during culture, is fumigation with Bladafume against thrips.
Does someone have a hypothesis for these abnormal flowers?
Thank you,

Claire Piette

Hi Claire, I have seen abnormal blooms on Spathi`s but generally in
commercially grown (and sprayed?) hybrids. Have you had them for a long
time, and they have never done tis before??? Are they store-bought or wild
collected species??
The hybrids sometimes produce double spathes, no spathes, double or forked
spadices, all kinds of deformities. I don`t know if it`s the breeding, OR
the sprays to make them all bloom together, or fungicides or what it may be.

Hope this helps,

Cheers,

Julius

Claire - it used to be fairly common to see abnormalities in commercial spath
crops that came from tissue culture, but in recent years I haven't seen that
as a problem too often. It is always a possibility with micropropagation,
however.

Hmmm...this is a little off-subject re: aroids, but I was just reminded of
something I have seen in cultivated Codiaeums, especially the yellow-marked
varieties. Near (but not at) the tip of the leaf is a little filament,
which occasionally shows a rudimentary leaf blade at its tip. The
filament, I presume is normal, but I do wonder about that secondary blade.
Is there not some aroid which occasionally does this? I cannot recall
which, but I have read about it.
