  1. Abbreviations refer to Table 4. Sig p-values obtained by t-test between the 10th and 30th rings in a provenance or all sample trees. F-values and p-values were obtained with a one-way ANOVA among provenances. There were four sample trees in the static bending test in Khentii due to a failure to obtain data during the testing.
