中文摘要：

多数林木的幼年期长、始花期晚,为了探索林木早花的分子机制,克服经济林木育种周期长的难题,为进一步的林木童期调控和分子育种研究奠定基础,综述了高等植物的成花假说、成花诱导分子机理、林木成花相关基因的克隆及相关生理信号的研究进展。

英文摘要：

Most forest trees have a long juvenile phase, and late flowering phase. In order to research molecular mechanisms of flowering development of forest trees, the researches are reviewed on flowering development hypothesis, molecular mechanisms of flower induction, clone of gene and physiological signals related to flowering development.
