Fig. 3: Light micrographs of petiole in the control rudimentary leaves of ‘Nuomici’ litchi.

Leaf petioles were collected at 0 d a-c, 1 d d-f, 3 d g-i, 5 d j-l, 7 d m-o, and 9 d p-rafter water treatment (control). Micrographs in the second column are enlarged images of the upper part of the black rectangular regions marked in the same line of the first column. Micrographs in the third column are enlarged images of the lower part of the black rectangular regions marked in the same line of the first column. Arrows are longitudinal splitting cortical cells.
