摘要
综述了关于显花植物童性的生理机制,生理生化标记,童期调控和花诱导等方面的经典理论和最新研究进展。学术界有3种假说解释植物由童期向成年期转变的生理机制,许多形态、生理生化指标可以作为植物童性的标记,通过环境、栽培措施、营养物质等条件的改变或施用生长调节剂可以促进植物阶段转变。
The classic concepts and recent advances on the physiological mechanism, biological marker and the regulation of juvenility in flowering plant were reviewed. Florigen/antiflorigen concept, nutrient diversion hypothesis and multifactorial control are the three temporarily accepted hypotheses involved in the phase change. Many morphological, physiological and biochemical characters could be identified as the markers of juvenile or adult phase. The transition to reproductive phase could be accelerated with plant growth regulators, cultivation techniques and the changes in nutrition or environments.
