Growth, but not survival, differed significantly between the two seed sources
(Figure 1, Table 2). Effects were clearly evident 36 months after planting
(Figure 2). Trees from the local seed source were significantly taller, had larger
mean basal stem diameter, and more aboveground wood biomass than trees
from the off-site seed source at all rates of P fertilization (Table 3). Sample
means of branchiness were also greater for local-seed-source trees at all rates
of P fertilization, but the only statistically significant difference was at 600 kg
P ha−1. Crown volume was significantly greater for local than for off-site trees
