Seep propagation of Cercidiphyllum

	Greetings all!
	I am in the midst of some propagation research on katsura trees, 
yes both of them, Cercidiphyllum japonicum and C. magnificum.  The focus 
is on seed propagation.
	The literature is a bit vague and members of the industry do a 
variety of different things to the seed in order to germinate it.

	There is no dormancy that needs to be broken in order to induce 
germination, although we have found that a short period of stratification 
has promoted germination, as does light when seeds have not be stratified 
(although only marginally).

	Our research and results are a bit more in depth than what I have 
stated above.  I would be interested in trading information with anybody 
on this list who may have/desire info on the propagation, production, and 
or cultivation of this fine tree.

	Many Thanks
	Michael
