Question
I am looking for a source of dwarf rootstock for various species of tropical fruits. Have any idea where I may locate them. I'll be in Belize CA

Answer
Hi David,
Thanx for your question.  I am not a tropical fruit expert but I would try the University of California Cooperative Extension Service
http://ucanr.org/  You need to ask them about shipping agricultural products outside of the U.S. too.

I would also contact the Ministry of Agriculture and Fisheries in Belize about importation of agricultural products and they may have companies dealing in dwarf root stock there or in the surrounding nations.  Here's a link.

This is pretty much outside of my scope of expertise.  I hope this helps.
