storage of Dracontium tubercles

From: "Scott Taylor" staylor at brevardparks.com> on 2003.11.18 at 21:59:40(10831) Hello: Can someone advise me on the best method for storage of tubercles of Dracontium? Should they be stored dry, on in soil? And in general, how many will germinate and is this on the same 'schedule' as the main tuber? Thank you. D.

Maybe that's why so many are produced. Strangely enough, with the tubercles of the Dracontium ally Pycnospatha, the results are much better.....

From: "Petra Schmidt" petra at plantdelights.com> on 2003.11.19 at 11:52:29(10837) I've also cut (wounded) the base of the tubericles and dipped them into rooting hormone to see if they would root more quickly but it didn't help...their dormancy is quite long. Placing them into fine milled spaghnum vs long fibrous spaghnum vs potting soil didn't make a difference either but keeping them in semi-dark conditions (beneath bench tops instead of atop bench tops) made a slight difference in breaking dormancy (darker is better). My next step is to soak them in water before planting...will keep you posted.
