Leaf fluorescence (discontinued)

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.

本数据集通过对三类样地的叶绿素荧光（chlorophyll fluorescence）进行间接测量，以监测紫外线-B辐射（UV-B radiation）增强对植物胁迫的影响：具体包括对照组、加装可滤除UV-B辐射滤膜的样地，以及使用未滤除UV-B辐射的薄膜的滤膜对照组。测量工作在以黑果岩高兰（Empetrum nigrum）为优势种，矮桦（Betula nana）与越橘（Vaccinium uliginosum）为亚优势种的中生性矮灌丛生境中开展，测量对象为该生境中的矮桦与越橘。如需获取更多细节，请查阅该网站上最新发布的BioBasis手册。
