Information about plant materials of construction in artefacts advances knowledge about human history, agriculture, trade, migration and adaptation to new environments. Typically, materials identification in artefacts made from plants is problematic, since processing, age, dirt and surface treatments can mask identifying features, while ethical considerations relating to sampling limit the use of some analytical techniques. The study tests the usefulness of polarized light microscopy for identifying the New Zealand and Pacific plant species used to make tapa, indicating birefringent and morphological characteristics that can be used to differentiate fibres at the level Moraceae (Pacific; from genera Artocarpus, Broussonetia and Ficus) and Malvaceae (New Zealand; from genera Hoheria and Plangianthus).

偏振光显微镜为制做西班牙小吃的植物注入了新光

有关人工制品中建筑植物材料的信息可增进有关人类历史，农业，贸易，移民和适应新环境的知识。通常，由于加工，年龄，污垢和表面处理可能掩盖识别特征，因此在由植物制成的人工制品中进行材料识别是有问题的，而与采样有关的道德考量限制了某些分析技术的使用。这项研究测试了偏振光显微镜在识别用于制作西班牙小吃的新西兰和太平洋植物物种方面的有用性，表明可用于区分桑科（太平洋）水平的纤维的双折射和形态特征（从面包果，布鲁氏松属和榕属中分离出来）。）和Malvaceae（新西兰；Hoheria和Plangianthus属）。
