Norharmane is a secondary metabolite that appears in different species of land plants. In this paper, we investigated for the first time the specificity of norharmane through germination and growth tests on some crops as Zea mays L. (maize), Triticum aestivum L. (wheat), Oryza sativa L. (rice) and Lactuca sativa L. (lettuce) and weeds as Amaranthus retroflexus L. (amaranth), Echinochloa crus-galli L. (barnyard grass), Plantago lanceolata L. (ribwort), Portulaca oleracea L. (common purslane) and Avena fatua L. (wild oat), and its phytotoxic capacity on the metabolism of adult Arabidopsis thaliana L. (thale cress) by measuring chlorophyll a fluorescence, pigment content, total proteins, osmotic potential and morphological analysis. Norharmane had an inhibitory effect on the germination of A. fatua and P. lanceolata, and the growth of P. oleracea, E. crus-galli and A. retroflexus. On adult A. thaliana plants, the compound was more effective to watering, leading to water stress that compromised the growth of the plants and ultimately affected the photosynthetic apparatus. Therefore, this research shows that norharmane not only affects seedlings’ metabolism, but also damages the metabolism of adult plants and can be a potential model for a future bioherbicide given its specificity.

天然化合物去氯烷对农作物，杂草和模型植物的植物毒活性

诺曼丹是次生代谢产物，出现在不同种类的陆地植物中。在本文中，我们通过对一些作物发芽和生长试验，研究首次norharmane的特异性玉米玉米大号。（玉米），小麦小麦 L.（小麦），稻属（水稻）和莴苣属水稻L. （莴苣）和杂草如苋苋 属（苋菜），稗crus-稗 L.（稗草），车前子lanceolata L.（ribwort），Portulaca oleracea L.（普通马齿sl ）和Avena 通过测定叶绿素a的荧光，色素含量，总蛋白，渗透势和形态分析，对法塔图 L.（野生燕麦）及其对成年拟南芥 （拟南芥）代谢的植物毒性能力进行了研究。诺曼丹对A的萌发具有抑制作用。燕麦和P 。lanceolata和P的生长。甘蓝，ê 。crus-加利和一个。后屈。在成人拟南芥上 在植物中，该化合物对浇水更有效，导致水分胁迫，损害了植物的生长并最终影响了光合作用。因此，这项研究表明，降冰片烷不仅会影响幼苗的代谢，而且还会损害成年植物的代谢，并且鉴于其特异性，可以成为未来生物除草剂的潜在模型。
