As observed in the wild there's some trees, or better say a few that set a lot of fruit, lots, sorry but I don't have an idea how many pounds or kilos would that be, taking a wild guess 250 pound maybe? Those are mature trees, then there's another who set moderate amounts of fruit and then for the most part the ones who doesn't, why don't? I don't know, Omar Páez member of TFF came this February with the Botanical director of Yale University and another botanic from UNAM, We took them to collect flowers for a DNA test, Omar is doing his thesis about this Garcinia, he said he'll have some news for this summer, but haven't received any feedback yet, that's is why is good to have a few grafted trees to ensure production,
