breaking dormancy in Amorphophallus

From: StroWi at t-online.de (StroWi) on 2001.04.17 at 00:24:15(6186) Dear Aroiders! I wonder, if there is anyone who has tried to break dormancy in Amorphophallus spec.? +More I heard, that dipping Dioscorea tubers in ethylene producing solutions will decrease dormancy while gibberellic acid will increase dormancy. Does anyone have experience with something like that in Amorph. spec.??? Any comments welcome! Thanks in advance, Bernhard.

From: Piabinha at aol.com on 2001.04.18 at 03:33:58(6198) i still have some Am. tubers from last year's distribution by the almighty lord p. that have not broken dormancy. either that, or they are dead. is it possible they are dormant for so long? tsuh yang

From: GeoffAroid at aol.com on 2001.04.18 at 14:36:23(6201) tsuh yang, I have had mature tubers of Amorphs sit on the bench dormant for 14 months before deciding they want to wake up, and that despite giving them warmth and moisture. They obviously have their own internal clock which they follow regardless of what we would like. Geoffrey

From: StroWi at t-online.de (StroWi) on 2001.04.19 at 01:40:21(6209) Dear Clarence Waldron, DearMichael Riley, Dear Tsuh Yang, Dear All, Thanks for your replies! Letting the Amorphs going their (natural) way and giving them favourable conditions is definitely a good way to get them out of dormancy. My point was rather the one Tsuh Yang mentioned. What to do with the ones which should (normally) start to grow but won't. I remember,too, that Wilbert H. and S. Ittenbach mentionend in their article on the cultivation of Amorphs that offsets sometimes refuse to start growing for years and then start (if they don't die, finally). So the question is more precise, what to do with tubers and esp. offsets that are due to grow in a normal cycle of dormancy and growing but won't. I thought that growth regulators (ethelene or maybe cytokinines) might be worth a trial. +More Is there anything known in aroids in this respect? Any comments wolcome! Thanks, Bernhard.

From: Steve Marak samarak at arachne.uark.edu> on 2001.04.19 at 03:41:05(6210) I mentioned a few days ago, in discussion on growing Amorphs in pots vs. in the ground, that one of the reasons I keep all mine except konjac in pots is dormancy. They seem incredibly stubborn, refusing to break dormancy until good and ready and then refusing to stay dormant a day longer no matter what I do. This has led me to a regimen of benign neglect that generally works well. To use the recent acquisitions from Wilbert as examples, they arrived dormant. Within a few days, I potted them all, using my standard potting mix. They were watered in very lightly - had the mix been damp, I might not have watered them in at all. They'll all be put on a shaded shelf, in a position where they won't accidentally get watered when I'm flailing about with the hose. To lower risk of rot - not that that's been a problem - I'll water just enough to keep the soil slightly moist. I check them every few days. When I see one breaking dormancy, that pot is moved to a moderately high light shelf, and receives more water and attention in general. When the leaf starts yellowing and showing signs of impending dormancy again, I reduce water gradually, then move the pot back to the "inactive" shelf. They are only repotted to remove offsets or when the tuber outgrows the pot or the soil condition gets that "poor" look. The advantages for someone like me are that I don't have to worry about conditions outdoors, or checking bagged up tubers and missing one and having it exhaust itself (which I've done), and even if I'm away from home for a week or so and one does break dormancy, no problem - there are nutrients and a small amount of moisture available. And I'm never "fighting" the plants, trying to induce dormancy or growth when they aren't in the mood. Not to mention that it minimizes effort on my part and makes more efficient use of my limited greenhouse space. The only real problem so far is that due to Wilbert's generosity over the last few years, if they were to all break dormancy at once, I wouldn't know where to put them. But that's a problem I'm happy to have. Steve +More -- Steve Marak -- samarak@arachne.uark.edu
