Slice observation of strawberry stolon. (a) Growth arrest in the first node and its stepping into dormancy; (b) Continuous development as a new stolon branch upon dormancy release; (c) Arrows indicate the trifoliolate ramet leave buds in the second node; (d) Vascular bundles (arrow) of the new developing stolon in the second node connected to the primary stolon; (e) The tissues from the outside to the inside of the stolon are epidermal hair (purple) and epidermis (orange), thick cortex (red), cambium (green; composed of a large number of parenchymatous cells), phloem (blue), xylem (grey), and pith (black); (f–g) vascular tissue of the lateral buds on the first (F, orange arrow) and second nodes (G, orange arrow) of the strawberry stolon connected inward with the vascular tissue of the primary stolon; (h-i) adventitious root primordia, which originating from the cambium. The scale bar is 0.5 mm in images (a-b) and (f-i) 1 mm in images (c-d) and 0.3 mm in image (e)
