Seed yield in the ancient torreya population as affected by year, tree age, and individual tree. A Seed yield per tree and stability of yield from 2011 to 2016. B Seed yield per tree for the four age groups of GT trees. Age groups are defined in Additional file 1: Table S1. C Variation in the yield of individual GT trees of age group III. The trees were divided into two groups (A and B) based on the temporal pattern of yield. The plot shows that the production of seeds was asynchronous for group A and B. Values are mean ± SE; n = 17 for group A and 28 for group B. GT grafted torreya, NGT non-grafted torreya
