摘　　要：开花是植物从营养生长进入生殖生长的转折点。近年的研究表明,FT就是寻找多年的成花素。FT蛋白在叶片合成,通过韧皮部从芽接部位移动到接穗或根部,其过表达常导致植物提早开花,以上特点在促进木本植物提早开花、缩短童期、加速育种具有重要价值。综述FT蛋白的移动为成花必须,FT蛋白芽接移动性在一年生及多年生植物的差异、FT促进观赏植物提早开花、利用FT加速育种进程等方面的进展,为相关研究提供参考。Flowering is the turning point from vegetative growth to reproductive growth of plants. Recent research showed that flowering locus T （FT） was the florigen which was sought for years. FT protein is synthesized in leaves, moving from grafting junction to scion and root via phloem, and its overexpression would induce precocious flowering of plants. The FT overexpression has important values in facilitating precocious flowering, shortening juvenile phase and accelerating breeding of woody plants. Recent main progresses in the movement of FT protein, FT induced precocious flowering in ornamental plants, and accelerating plant breeding with FT were reviewed in this paper.
