Morphological and histological properties of adventitious root primodium formation in the stem base of chrysanthemum ‘Jinba’ cuttings. Anatomy of adventitious root primodium formation (a) 0 d post excision, typical stem anatomy consists of the cortex (Co), the pith parenchyma (Pi) and a ring of vessels with phloem (Ph), cambium (Ca), and xylem (Xy) cells; 5 d after cutting, the first differentiated root primordia can be seen; Bars = 500 μm. Morphology of 0 d and 5 d cuttings (b). The arrow indicated the adventitious root, zoomed image shows the cutting position.
