Re: Pollenation of D. gigas.

From: Eduardo Gomes Goncalves <eggon at guarany.cpd.unb.br> on 1997.04.08 at 01:51:46(585) Dear Julius and Hans, I'm trying to germinate seeds from both Dracontium margaretae and D. bogneri. I sowed them 4 weeks ago and nothing happened yet. I think they will only germinate in the next growing season (early October), with the first rains of our southern spring. It's a very predictable pattern here in the Central areas of South America, where the winter is somewhat dry and it is not suitable for the growth of seedlings. Maybe time is the key factor. I really don't know if such pattern works for species from Central America (as D. gigas), but it can be a clue. Probably Guanghua can help us... Whatever, I'll notice you when mine sprout. Best wishes, Eduardo. +More On Fri, 4 Apr 1997, Julius Boos wrote: > Dear Hans, I believe that you would have to place pollen from the ELDER of > the two infloresences onto the spadix of the YOUNGER as SOON as it opens, as > only at this stage is the second [and younger] infloresence at female > anthesis.
