关于植物各种光温反应现象的统一模型

本文提出了一个统一的植物光温反应理论模型。它把植物的各种光温反应现象,包括短日植物的光温反应与长日植物的光温反应,定性的光温反应与定量的光温反应,光周期反应与温度反应,以及温度反应中的低温反应(包括春化反应)与积温反应等统一了起来。应用这一模型可对小麦生长发育中常见的各种光温反应现象和水稻光敏不育系的低温可育现象作出统一的解释。

An Integrated Model on Various Plant Photothermal Responses

An integrated model on plant photothermal responses has been developed under the principle that photoperiod and temperature are inextricably interacting in their modulation of plant growth and development, which describes photoperiodism, vernalization and other kinds of temperature responses of both long-day plants and short-day plants by a single pattern. It proves able to interpret the diversified results from studies of vernalization and photoperiodism in wheat, and able to settle the debates whether a process is dominated by photoperiod or temperature. It also gives satisfactory interpretation on temperature response of sterility of some so-called photoperiod sensitive male sterile lines of rice.
