Amorphophallus growing season (was konjac ques.)

From: markdim at azstarnet.com (Mark A. Dimmitt) on 1997.09.07 at 01:59:14(1169) I've been growing several species in my greenhouse at 32 degrees north latitude (Tucson, Arizona) for several to many years. My A. konjac, paeoniifolius, bulbifer, Syndandrospadix verm., and Pseudodracontium sp. are all very seasonal. Though they sprout at very different times in spring, they all go dormant in September or October. The Pseudodrac. may keep its leaves all winter, but stops producing new ones. My A. titanum and atroviridis are completely aseasonal. I've watched the two clones of titanum most closely. They produce a leaf that lasts 12 to 15 months, then drop it for a few weeks to two months. This year they both lost their leaves in mid August, and are already pushing new ones. Now for my question: My larger titanum will probably hit my 10-foot roof this time. Is there any way to shorten the petiole without harming the growth of the tuber? Can't grow them outdoors here - all of my amorphos are killed by a few weeks of 105+ (40 C) temps.
