As a Worldwide Exporter and wholesaler of tropical seeds, my company makes a small but important contribution to the Mangoes you buy at the store. This is about #11 Mangoes. The #11 Mango is a very quick growing and fast producing Mango tree. We recently shipped out 10,000 #11 (660 pounds) Mangoes to a massive nursery in Florida. Now the #11 Mango is very fast producing, but it is very bland as a Mango. What the Nursery does is germinate the #11 seeds and grow them to use as root stock for grafting a more tasty Mango. What this does is allow them to produce awesome mangoes about 2-3 years faster than a non grafted Mango. Here is a #11 Mango, a photo of 10,000 Mango seeds drying. (Took about 5 days to dry, becase of the rainy season), and 10,000 Mango seeds ready for export.
