Table 4.
Spearman's rank-based correlation coefficients (with probabilities of significance below, in parentheses) between the shade tolerance index and crown traits measured from CT scanning data and CT images appropriately processed, by group depending on leaf type (a) needlelike (n = 10) and (b) scalelike (n = 5); the correlations statistically significant at 5% are bolded and underlined; those only significant at 10% are simply underlined. For the definition of abbreviations, please see Table 1.
