Littleleaf linden (Tilia cordata) P values of a priori contrasts for cross-sectional trunk area growth for 3 years after transplanting, mean shoot extension (mean of five shoots per replication) for 2 years after transplanting, and leaf nitrogen content (pooled sample of five leaves per replication) the third year after transplanting.

↵^zContrasts are for rate of change from multivariate repeated measures analysis of variance (n = 6).
↵^yn = 6 with five subsamples per replication.
↵^xNitrogen content is percent of dry weight (n = 4).
