A method for measuring the metabolic energy of plant leaf cells

Abstract

The invention discloses a method for measuring plant leaf cell metabolic energy, and belongs to the technical field of biophysical information detection. A measuring device comprises a bracket, foam plates, electrode plates, wires, an iron block and a plastic rod, wherein the foam plates embedded with the electrode plates are separately adhered to the bottom end of the bracket and the plastic rod.The electrode plates are connected with an LCR tester through the wires during using, the two electrode plates clamp a plant leaf to be measured, and physiological resistance, physiological impedanceand physiological capacitance of the plant leaf under different clamping force are simultaneously measured in a parallel mode. According to the Gibbs free energy equation and the Nernst equation, models of the physiological capacitance of the plant leaf changing with the clamping force, the physiological resistance of the plant leaf changing with the clamping force and the physiological impedanceof the plant leaf changing with the clamping force are further constructed, and the plant leaf cell metabolic energy is calculated jointly by using parameters of the three models.

Description

technical field [0001] The invention belongs to the technical field of biophysical information detection, and specifically relates to a method for measuring the metabolic energy of plant leaf cells, which can quickly and non-destructively detect the metabolic energy of plant leaf cells, and judge the supply relationship of water and substances in the plant leaf system. Background technique [0002] "Energy" is classically defined as the ability of an object to do work. Energy is a measure of the motion of matter, corresponding to different motion forms of matter, energy also has different forms. Life activities are the sum of sequence reactions leading to a highly ordered state of the system, and consume energy. Although different organisms can use different sources of energy; however, in reality a large number of biochemical reactions and cellular processes in the body can only accept metabolic energy, the form of energy that is directly available for the metabolism of the...

Problems solved by technology

Although the internal energy charge state is currently used to reflect the metabolic energy of cells in organisms, in fact, the demand and supply of metabolic energy for the assimilation and dissimilation of many substances are not clear, and the demand and supply of metabolic energy for many metabolic processes are also unclear. , therefore, only measuring the state of energy charge in cells cannot truly represent the metabolic energy of plant cells

[0005] In addition, even if the state of intracellular energy charge can reflect the metabolic energy of cells in an organism, the state of intracellular energy charge of the living body is also required, which is difficult to achieve with existing technologies
