Source of GT rootstocks. a The percentage of recent GT rootstocks from NGT saplings grown by farmers. b PCoA based on genetic distance among the age groups of GT rootstocks and NGT trees. No genetic pattern among age groups of rootstocks and NGT trees indirectly indicated that NGT saplings have been the historical source of GT rootstocks. Values are mean ± SE. GT grafted torreya, NGT non-grafted torreya
