Abstract

The chlorophyll a fluorescence measurement method is used to determine the efficiency of the photosynthetic apparatus and to assess the physiological state of photosynthetic organisms. The measurement is simple, fast, and noninvasive. It is a precise tool to study photosynthesis response under stress conditions or to assess the impact of specific environmental factors on plants. Here we describe the usage of this method in environmental-controlled plant production systems differing in temperature or light source on the growth and development of common buckwheat.

摘要

叶绿素荧光测量法用于确定光合作用器的效率，并评估光合生物的生理状态。该测量方法简单、快速且非侵入性，是研究胁迫条件下光合作用响应或评估特定环境因素对植物影响的精确工具。在这里，我们描述了该方法在环境控制的植物生产系统中的应用，该系统在温度或光源方面存在差异，以研究其对普通荞麦生长和发育的影响。
