  storage of Dracontium tubercles
From: "Scott Taylor" staylor at brevardparks.com> on 2003.11.18 at 13:59:40(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.

My experience:

- they do not dry out too easily but on the other hand many seem to go into
a coma, irrespective of how you treat them
- I keep them on the dormant mother-tuber as long as possible
- I put them in soil immediately after separating, not necessarily as wet as
when they are growing
- I check regularly whether they are waking up
- the net result is usually that only some 20 - 30 % of them decides to wake
up (sometimes even less)

So, the result is not overwhelming but I think that is innate to Dracontium
tubercles. Maybe that's why so many are produced. Strangely enough, with the
tubercles of the Dracontium ally Pycnospatha, the results are much
better.....

Cheerio,
Wilbert

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.
