花期调控需要有效的人工诱导。在植物的幼年期 ,任何诱导都是无效的 ,因此 ,需要确定结束其的时间。本文对用于判断幼年期的量化指标、判断准则和常规步骤等进行了总结 ,确定了常用的标准。被诱导的阶段转变指的是人工诱导下植物从幼年期向成熟期的转变过程。本文归纳出五种被诱导的阶段转变的基本类型 ,对每种类型的特征进行了描述和举例 ,确定了幼年期结束的判断方法 ,讨论了影响判断的因子及长期存在的争议。
Flowering regulation requires effective artificial induction. At the infancy of a plant, any induction is ineffective, so the time to finish it needs to be determined. This article summarizes the quantitative indicators, judgment criteria, and routine steps used to determine juvenile onset, and establishes common criteria. The induced phase transition refers to the process of plant-induced transformation from infancy to maturity. This paper summarizes the five basic types of induced phase transitions, describes and provides examples for each type of characteristics, determines the judging method of the end of juvenile period, discusses the factors that affect judgment and the long-standing controversies.
