Dualex是一款源自于法國國家科學院 (CNRS)及巴黎第十一大學技術,由奧地利PESSL公司生產(原法國Force-A公司)開發(fā)的新型多功能葉片測量儀。它可同時準確測量葉片的葉綠素含量、葉片表層的類黃酮和花青素含量,適用于植物生理學和農學(如水稻葉綠素濃度,玉米氮素狀況,葡萄藤等)相關研究。
其測量對象可以是單子葉植物,雙子葉植物或多年生植物。這款設備簡單易用,可進行實時和非破壞性測量。由于不需要校準標定和事先的樣品制備,測量工作可在實驗室或現場完成。此外,該設備在各種溫度的和環(huán)境光照條件下均可正常使用。系統(tǒng)采用專利設計,光學傳感器可進行簡單、快速、無損測量葉片中的葉綠素、多酚以及花青素。
摘要
很難為每個地方找到合適的農業(yè)能源物種且這些物種具有潛在的生物量。因此,有必要研究新物種。通過對這些物種的種植研究,我們可以了解它們作為能源作物的行為。白榆是一種很好的能源作物。然而,最好使用更多的本土物種和其他特征物種,因此我們研究了五個不同的榆樹無性系。其中,比較了用DUALEX®單位測量的葉綠素和多酚指數。被比較的克。“Olma de Ribatajada”(小榆的克隆體),“Olma de Pareja”(小榆的克隆體),金葉榆的克隆。此外,還研究了白榆的兩個不同無性系的葉綠素指數、黃酮醇指數、花青素指數和NBI®氮狀態(tài)(葉綠素/黃酮醇比率)。這篇文章研究在“El Encín”莊園進行。種植不同無性系的插條,七個月后進行測量。隨著時間的推移,有必要繼續(xù)研究無性系和其他形態(tài)農藝性狀,以確定更適合生物質能源作物的榆樹種類。

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.
