According to what I've read, no, they are not synonyms. Apparently P. 
sibirica (or P. armeniaca var. sibirica) is not of much use for fruit, 
but may have been used a little in breeding with what success I don't know.

Apparently Oikos Tree Crops sells Prunus sibirica in the U.S. Their 
website says it is the earliest of apricots to bloom which makes me 
wonder about the claims it is a better rootstock than P. mandshurica.

According to
<http://www.gardenbuddies.com/forum/messages/64189/1250743.html>
there is a tree or trees of P. sibirica onthe grounds of Olds College, 
Olds, Alberta. I wouldn't be surprised if the Unversity of Saskatchewan 
at Saskatoon has it also.
