a Representative images of bulbs in TRV control lines and TRV-LoSOC1 silenced lines after infiltration under 4 °C long-temperature cold treatment for 8 weeks. b Representative images of bulbs in TRV control lines and TRV-LoFUL silenced lines under 12 °C bud-forcing treatment for 15 days. TP tepal primordium, FAM flower apical meristem, SAM, shoot apical meristem. c Statistics of the ratios of central bud length to bulb length of TRV (n = 15 per replicate) and TRV-LoSOC1 (n = 15 per replicate) lines after infiltration under 4 °C long-temperature cold treatment for 8 weeks. Data are presented as mean ± s.d. of three technical replicates (two-sided Student’s t-test; **: P < 0.01). **P = 0.0047. d The expression pattern of LoFUL in SAMs under 4 °C from 0 week to 8 weeks and SAMs under 12 °C bud-forcing treatment from 3 days to 15 days. W, week; d, day. Error bars are shown as the mean ± s.d. of three biological replicates. ANOVA with Turkey’s HSD tests for pairwise comparisons is used for data analysis and the letters represent significant differences (P = 0.0001). **P = 0.0001. e Statistics of the number of flower buds of TRV and TRV-LoFUL lines (n = 15) with 12 °C bud-forcing treatment for 15 days. Error bars stand for mean ± s.d. (two-sided Student’s t-test; **: P < 0.01). **P < 0.0001. f Statistics of flower bud transition rate of TRV (n = 15) and TRV-LoFUL (n = 15) lines with 12 °C bud-forcing treatment for 15 days. Error bars stand for mean ± s.d. of three technical replicates (two-sided Student’s t-test; **: P < 0.01). **P < 0.0001. Source data are provided as a Source Data file.
