Re: [Aroid-l] Amorphophallus tuber growth without leaf?

Peter,
Soluble sugars would have a higher affinity for water as well as increase the overall molality of the cell sap. I would follow that a dehydrated plant (one sitting dry on a shelf) would rapidly take up water both because of the dehydration and the starch breakdown. Example: most seeds store energy as starches, but during imbibition they swell several times their original size.

I give some more details.
1st case) A. kiusianus - plant not even developed the leaf correctly, never unfolded completely and died fast away. The tuber tripples it's size.
2nd case) Helicodiceros muscivorus - i planted several tubers (some very tiny) in a pot, just one realy thrived. Meanwhile the leaf begin to die back and I digged down to see what the tuber do. And found beneath the biggest tuber (the one with leaf) another tuber even bigger than the other ever was.

greetings
Peter
