Effects of decapitation and auxin on bulbils of lily. A Schematic plot showed the growth of bulbils after decapitation and application of auxin at USs and LSs of lily. Squares in orange and blue background indicate USs and LSs, respectively. Red circles represent bulbils. B, C The percentage of lily with bulbils (B) and total bulbils number (C) of 30 lily plants was counted. D-L, Scanning electron microscopic images of USs and leaf axil. Scale bars = 1 mm (D-L). The leaf axils indicated with magenta circles of CK (D) and treated plants with bulbils (E). The vertical section of USs treated with HI (F) and CK (G). The callus-like cells were circled with magenta ovals (F). Cross-section of USs treated with T (J), LI (H, I) and HI (K, L). M Number of parenchymal cell from pith to epidermis (divided into inner, middle and outer part) was counted. The orange, blue and turquoise boxes were exampled for cell counts of inner, middle and outer parts of stem. Asterisks indicate significant differences of the total cell number among TUS, LIUS, and HIUS, as determined by the Tukey’s HSD test (** P < 0.01). N-S Changes in the concents of six endogenous hormones at USs and LSs of different treatments: IAAN (N), ZR (O), ABA (P), GA3 (Q), JA (R) and BR (S)
