Fig. 4From: Comprehensive transcriptomic analysis provides new insights into the mechanism of ray floret morphogenesis in chrysanthemumObservation and statistics of CVW and CVT petal epidermal cells of ray floret . a-b The materials from the center of the top, middle and basal regions of CVW (a) and CVT (b) ray florets were sampled for morphological characterization of petal epidermal cells. c-d Epidermal cells in the top, middle and basal regions of CVW and CVT ray floret petals were observed using a scanning electron microscope. Scale bar = 100 μm. e Measurement of adaxial epidermal cell numbers in CVW and CVT ray floret petals. f Measurement of abaxial epidermal cell numbers in CVW and CVT ray floret petalsBack to article page
