Fluorescence of vegetation

The effect of increased UV-B radiation on plant stress is monitored indirectly by measuring chlorophyll fluorescence in three series of plots: Controls, plots with a filter excluding UV-B, and filter controls with a film without exclusion of UV-B. Measurements of chlorophyll fluorescence are carried out on Betula nana and Vaccinium uliginosum in a mesic dwarf shrub heath dominated by Empetrum nigrum and with B. nana and V. uliginosum as subdominant species.

本研究通过对三组样地的叶绿素荧光（chlorophyll fluorescence）进行间接测定，监测增强型UV-B辐射对植物胁迫的影响，三组样地分别为：对照组、加装可滤除UV-B辐射滤膜的样地，以及加装无UV-B辐射滤除功能薄膜的滤膜对照组。测定对象为以黑果岩高兰（Empetrum nigrum）为优势种，矮桦（Betula nana）与湿地越橘（Vaccinium uliginosum）为亚优势种的中生性矮灌木灌丛中的矮桦与湿地越橘。如需了解更多详细信息，请参阅该网站发布的最新BioBasis手册。
