P. gigantocarpa cross sections stem. (a–d, i) Plants 15 days under different shade intensities. (e–h, j) Plants 60 days under different shade intensities. (a, e) Seedlings in full sun, (b, f) low, (c, g) moderate, and (d, h) high shade intensity. (i, j) Epidermis and cortex. Cambial activity (CA), xylem (x), cambium (c), and phloem (p).
