摘要
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。
Manipulation of flowering requires de termining the end of the juvenile phase,during which an inductive condition has no effect on flowering.Quantified parameters,determination criteria,and routine procedures to assess the end of juvenility are reviewed and constant standards a re provided.The transition from the juvenile to mature phase under inductive con ditions is defined as induced phase change,which is summarized into five basic p atterns .Characteristics and examples of each pattern,determination of the end o f the juvenile stage in each pattern,factors affecting determinate of induced ph ase change and longexisting controversies related to phase change are also dis cussed.
