Plant growth regulator composition as well as preparation method and application thereof

The present invention relates to a plant growth regulator composition comprising a first component involved in transcriptional level regulation of cell development in response to cell development, a second component that induces a promoter response in response to cell division, and a third component that provides a base material for vital activity in which the first component and the second component are involved. The plant growth regulator composition can act on pedicels or inflorescence tissues of rosa benthamiana, so that the rosa benthamiana recovers a normal state with commercial value. 本发明涉及一种植物生长调节剂组合物，组合物包含响应于细胞发育而参与细胞发育转录水平调控的第一组分、诱导启动子应答以响应细胞分裂的第二组分和为第一组分、第二组分参与的生命活动所需提供基础材料的第三组分。一种植物生长调节剂组合物能够作用于弯头月季的花梗或花序组织处，从而使弯头月季恢复具有商业价值的正常状态。
