Figure 1From: Transcriptome profile analysis of flowering molecular processes of early flowering trifoliate orange mutant and the wild-type [Poncirus trifoliata (L.) Raf.] by massively parallel signature sequencingSchematic diagram of developmental stages involved in the flowering of precocious trifoliate orange. a, Seedling of precocious trifoliate orange (1 month). b, The shoot apical meristem of seedling begins self-pruning (October). c, The terminal bud and lateral buds of the juvenile trees became dormant after self-pruning (mid-October). d, The lateral buds develop into a spring shoot in the next year (late February). e, The spring shoot begins self-pruning (early April). f, After self-pruning (mid-April). g, h, The lateral bud becomes a leaf bud (from late April to mid-May). i, Sepal primordia arise (late April). j, Petal primordia arise (late April). k, Stamen primordia arise (early May). i, Pistil primordia arise (mid-May). m, n, Full-developed floral bud (late May). o, p, The early flower morphology of precocious trifoliate orange.Back to article page
