Roots also serve as the site for the synthesis of gibberellins (GA); they may also be sites involved in the interconversion of shoot-derived GA. GA activity related with dwarfing phenotype of rootstock.
Auxin can also be derived from roots; the root cap appears to be the most likely site of synthesis. IAA levels have been shown to change with the developmental age of roots and with other factors such as high mechanical soil impedance.

自动化专业英语
自动化专业英语自动化专业英语是指在自动化领域中使用英语进行交流和表达的专业英语。
自动化是一门综合性学科，涉及到机械、电子、计算机、控制等多个领域，因此在专业英语中需要掌握相关的词汇、表达方式和专业知识。
一、自动化专业英语词汇1. Automation（自动化）：The technique of making an apparatus, a process, or a system operate automatically.2. Control system（控制系统）：A system that manages, commands, directs, or regulates the behavior of other devices or systems.3. Programmable logic controller (PLC)（可编程逻辑控制器）：A digital computer used for automation of electromechanical processes.4. Sensor（传感器）：A device that detects and responds to some type of input from the physical environment.5. Actuator（执行器）：A component of a machine that is responsible for moving or controlling a mechanism.6. Feedback（反馈）：The process of returning part of the output of a system to its input.7. Process control（过程控制）：A system that uses sensors and feedback to automatically adjust the operation of a process.8. Industrial robot（工业机器人）：A robot system used for manufacturing, assembly, or material handling tasks.9. Human-machine interface (HMI)（人机界面）：The point of interaction between a human operator and a machine.10. SCADA (Supervisory Control and Data Acquisition)（监控与数据采集系统）：A system for remote monitoring and control of industrial processes.二、自动化专业英语表达方式1. Describing a process（描述过程）：To begin with, the raw materials are fed into the production line. Then, the sensors detect the input and send signals to the control system. The control system processes the signals and adjusts the parameters of the actuators accordingly. This ensures that the production process is carried out smoothly and efficiently.2. Explaining a control system（解释控制系统）：A control system consists of several components, including sensors, actuators, and a programmable logic controller (PLC). The sensors detect the input from the environment and send signals to the PLC. The PLC processes the signals and sends commands to the actuators. The actuators then move or control the mechanism based on the commands received. This allows the control system to regulate and maintain the desired behavior of the system.3. Discussing the importance of automation（讨论自动化的重要性）：Automation plays a crucial role in various industries. It improves efficiency, reduces human error, and increases productivity. By automating repetitive tasks, companies can save time and resources. Moreover, automation enables real-time monitoring and controlof processes, leading to better quality control and higher safety levels. In addition, automation allows for flexibility and scalability, as systems can be easily reprogrammedor reconfigured to adapt to changing requirements.4. Presenting the benefits of using industrial robots（介绍使用工业机器人的好处）：Industrial robots have revolutionized manufacturing processes. They can perform repetitive tasks with high precision and speed, resulting in increased productivity.Furthermore, robots can operate in hazardous environments, reducing the risk to human workers. With their ability to handle heavy loads and work for extended periods, robots contribute to cost savings and improved efficiency. Additionally, robots can be programmed to perform complex tasks, such as assembly or welding, with minimal errors.三、自动化专业英语专业知识1. PID control（PID控制）：A control technique used in feedback control systems. It calculates an error value as the difference between the desired setpoint and the measured process variable. The control algorithm adjusts the output based on proportional, integral, and derivative terms to minimize the error and achieve stable control.2. Robotics（机器人技术）：The branch of engineering and science that deals with the design, construction, operation, and application of robots. It encompasses mechanical engineering, electrical engineering, computer science, and artificial intelligence.3. PLC programming（PLC编程）：The process of creating a set of instructions for a programmable logic controller. It involves defining input and output signals, designing the control logic, and implementing the desired functionality.4. HMI design（人机界面设计）：The process of creating an interface between a human operator and a machine. It involves designing user-friendly screens, buttons, and menus to facilitate interaction and control.5. SCADA system architecture（SCADA系统架构）：The structure and components of a supervisory control and data acquisition system. It typically consists of a human-machine interface, remote terminal units, communication networks, and a central control station.以上是关于自动化专业英语的标准格式文本，涵盖了词汇、表达方式和专业知识。

• When a load is connected to the source terminals (the circuit is then said to be loaded) and the circuit is closed, a current begins to flow round it. Now the voltage between source terminals 1 and 2 (called the terminal voltage) is not equal to its e.m.f. because of the voltage drop VS inside the source, that is, across the source resistance RS VS=RSI
