We Torreya Guardians, working with endangered Florida Torreya trees, are trying to understand differences in success of seeds or seedlings planted in wild forest settings northward in sync with climate change. Specifically, if the evergreen Torreya is planted beneath a pure deciduous canopy (near genera, such as Acer, that utilize the same mycorrhizal group) do the fungi transport sugars to the seedlings/saplings during full-shade summer, and then "value" the sugars produced by the little Torreyas in full-sun late fall and early spring? Note: This question arose for me as I posted my latest video of a site visit in central Ohio onto the Torreya Guardians homepage. The two seedlings in full-shade deciduous are thriving there.
