Fig. 7: Morphological variation of ray florets in hybrids.

Note: Only RFL is the same (a-1); only CTL is the same (a-2); only CSL is the same (a-3); CTL/RFL is the same (a-4). Ray floret length (RFL); corolla tube length (CTL); corolla splitting length (CSL). Morphological variation of flower heads with different numbers of florets (b-1). The scale bar represents 0.5 cm
