Dualex是一款源自于法国国家科学院 (CNRS)及巴黎第十一大学技术，由奥地利PESSL公司生产（原法国Force-A公司）开发的新型多功能叶片测量仪。它可同时准确测量叶片的叶绿素含量、叶片表层的类黄酮和花青素含量，适用于植物生理学和农学（如水稻叶绿素浓度，玉米氮素状况，葡萄藤等）相关研究。

其测量对象可以是单子叶植物，双子叶植物或多年生植物。这款设备简单易用，可进行实时和非破坏性测量。由于不需要校准标定和事先的样品制备，测量工作可在实验室或现场完成。此外，该设备在各种温度的和环境光照条件下均可正常使用。系统采用专利设计，光学传感器可进行简单、快速、无损测量叶片中的叶绿素、多酚以及花青素。

摘要

很难为每个地方找到合适的农业能源物种且这些物种具有潜在的生物量。因此，有必要研究新物种。通过对这些物种的种植研究，我们可以了解它们作为能源作物的行为。白榆是一种很好的能源作物。然而，最好使用更多的本土物种和其他特征物种，因此我们研究了五个不同的榆树无性系。其中，比较了用DUALEX®单位测量的叶绿素和多酚指数。被比较的克隆：“Olma de Ribatajada”（小榆的克隆体），“Olma de Pareja”（小榆的克隆体），金叶榆的克隆。此外，还研究了白榆的两个不同无性系的叶绿素指数、黄酮醇指数、花青素指数和NBI®氮状态（叶绿素/黄酮醇比率）。这篇文章研究在“El Encín”庄园进行。种植不同无性系的插条，七个月后进行测量。随着时间的推移，有必要继续研究无性系和其他形态农艺性状，以确定更适合生物质能源作物的榆树种类。

COMPARISON OF CHLOROPHYLL AND POLYPHENOLS INDEXES IN DIFFERENT SPECIES OF ELM FOR USE AS ENERGY CROPS

Abstract

Finding suitable agroenergetic species for each place and that these species are potential for biomass is difficult. For this reason, it is necessary to study new species. Studying these species from planting, we can get an idea of their behavior as an energy crop. Due to its characteristics, Ulmus pumila L. is a good species to use as energy crop. However, it is good to use more autochthonous species and with other characteristics, that is why we have studied five different clones of Elms. In them, we have compared the indices of chlorophyll and polyphenols, measured with the DUALEX® unit. The clones that were compared: "Olma de Ribatajada" (clone of Ulmus minor Mill.),"Olma de Pareja" (clone of Ulmus minor Mill.), a clone of Ulmus laevis Pall. moreover, two different clones of Ulmus pumila L. The chlorophyll index, flavonol index, anthocyanin index and the NBI® nitrogen status (chlorophylls/flavoles ratio), there were studied. This essay was located at the estate "El Encín" in Alcalá de Henares, belonging to IMIDRA. The cuttings of the different clones were planted and after seven months, the measurements were taken. It is necessary to continue studying the clones and other morphoagronomic characters over time in order to determine the species of elm that are more suitable for the energy crop of biomass.
