  Re: Contractile Roots
From: Dana Scholle <dana at homecom.com> on 1997.09.09 at 20:50:27(1199)
I' certainly not an expert, but what comes to mind would be that the
contractile roots keep the tuber in place and stabilize the petiole, then
as the season wears on, the tuber replenishes ans increases in weight. Then
when the plant begins to wither, so do the roots, which then loose the
ability to hold up the tuber and it would then collapse down into the space
below it. Just a guess?

I noticed the other day that my smallish Konjac is now putting out a
secondary something. I am assuming it could only be a leaf. I thought
Konjac was known for having only one petiole per season. I have a rapidly
growing Bulbifer (thanks to Mr. Martyn :) ) which is in the process of
putting up it's fourth and fifth leaves (at the same time, no less!!) But
the Konjac is a little puzzling. It's one of the black stem varieties from
Plant Delights. Has anyone else ever had this kind of thing happen?
