Old-growth Platycladus orientalis as a resource for reproductive capacity and genetic diversity.

Seed length ( p = 0.071; n = 8; Spearman’s rho = 0.667; marginally significant) and weight ( p = 0.037; n = 8; Spearman’s rho = 0.738) for these populations were positively correlated with the average values of the DBH ( Fig. 1a, b ): Older populations tended to produce heavier seeds.
