Group means depending on leaf type and corresponding standard errors for the shade tolerance index and the crown traits that were measured from CT scanning data and CT images for both groups of miniature conifers, together with the result of the statistical comparison of the two means per variable (AH₀, Accept the null hypothesis of equality of means; RH₀, Reject, at 5%).
