Clones of Fragaria were characterized by the attenuance (absorption) spectra of their photosynthetic apparatus. This method uses fourth derivative analysis of spectra of intact lamina of detached leaves at room temperature (20-25 C). Twenty-one different species and hybrids of Fragaria were examined. F. chiloensis accessions frequently have characteristic fourth derivative spectra distinct from that of other Fragaria species. These spectra are characterized by a strong band that appears to be photosystem I component Ca 693; and is correlated with a higher chlorophyll b content per unit area of leaf, and a lower chlorophyll a/b ratio.
草莓的克隆体的光合器官的消光（吸收）光谱具有特征性。该方法使用室温（20-25°C）下完整的离体叶片的光谱的四阶导数分析。检查了 21 个不同的草莓物种和杂种。F. chiloensis 品种的四阶导数光谱通常具有与其他草莓物种不同的特征。这些光谱的特征是出现了一个似乎是光系统 I 组分 Ca 693 的强带；并且与单位面积叶片的叶绿素 b 含量较高和叶绿素 a/b 比值较低相关。
