From: Gene expression profiling during adventitious root formation in carnation stem cuttings
Morphological changes in the ultrastructure of the basal stem of carnation cuttings during adventitious rooting. Light micrographs were taken from cross-sections of stem cutting basal regions in the 2003 R 8 (a-d) and 2101–02 MFR (e-h) cultivars, either treated with mock (a-b, e-f) or with auxin (c-d, g-h) at different time intervals (0 and 54 hAP). ca, cambium; cc, cell clusters; pl, phloem; xl, xylem. Scale bars: 50 μm
