关于向重力性的研究在很大程度上局限于初级根冠轴，以及理解那里观察到的典型垂直方向是如何保持的。许多侧向器官也是向重力的，通常与重力成特定的非垂直角。这些所谓的重力设定点角(GSA)很耐人寻味，因为它们的维持要求根和地上部的侧器官能够在重力矢量的作用下和在重力矢量的作用下影响热带生长。本章描述了与研究GSA控制的基本机制相关的方法和考虑。
The history of research on gravitropism has been largely confined to the primary root-shoot axis and to understanding how the typically vertical orientation observed there is maintained. Many lateral organs are gravitropic too and are often held at specific non-vertical angles relative to gravity. These so-called gravitropic setpoint angles (GSAs) are intriguing because their maintenance requires that root and shoot lateral organs are able to effect tropic growth both with and against the gravity vector. This chapter describes methods and considerations relevant to the investigation of mechanisms underlying GSA control.
