[Aroid-l] Amorphophallus from Thailand

From: alan_galloway at ncsu.edu (Alan Galloway) on 2007.11.02 at 20:18:55(16646) John, Most Thai Amorphs have a pretty regular growth/dormancy cycle. But some species are much more prone to skipping a season or two before either flowering or sending up a leaf. Am. pygmaeus, atroviridis, and tenuispadix seem to be much more prone to skipping a growth/flowering cycle. Am. parvulus and Am. napiger, and a couple of other species that grow these thin, long tubers also might fall into this 'skip a growth/flower cycle' pattern.........The reason I say they 'might' fall into this category, is that many years their tubers grow out of the bottom of the pot and are broken off when the pot is moved, so it could be the damage to the bottom of the tuber that causes them to skip a growth/flowering cycle. I've been trying to keep some detailed notes on this hypothesis over the last few years, but don't have enough data yet to determine if my hypothesis is valid.
