Seeking info Ginkgo plantation and quality control

- Which cultivars are used in the Ginkgo commercial plantations in The USA, France and China?
Also how do these commercial plantations propagate their plants to such large scales? I am asking this because we consider to start a Ginkgo project in Thailand.

- We are looking for a independent laboratory which can establish the quality of Ginkgo.Either a laboratory in Asia, The Netherlands or the USA is possible.We are aware of one such a lab. in The Netherlands who has such capacities but we must operate on a modest budget and the quoted costs by them for a single full analyses are very high.Look forward to your comments.
