Effect of Trifloxysulfuron sodium on growth of the mangrove, Avicennia marina

Plants were exposed to 6 concentrations of trifloxysulfuron for 28 days followed by 56 days of recovery after removal of the herbicide. During this time, assessments were made of appropriate parameters including shoot height, leaf number, fresh and dry weight. This study was designed to evaluate the effects of the sulfonylurea herbicide, trifloxysulfuron,on the growth of the mangrove Avicennia marina under tidal conditions. Data was analysed to detect significant deviations in these parameters from control values, and thus determine the NOAEC (no-observed adverse effect concentration).

将红树林植物白骨壤（Avicennia marina）暴露于6种浓度的三氟啶磺隆（trifloxysulfuron）环境中28天，随后移除除草剂，使其恢复生长56天。实验期间对相关生长参数进行测定，包括株高、叶片数、鲜重与干重。本研究旨在评估磺酰脲类除草剂三氟啶磺隆（trifloxysulfuron）在潮汐条件下对该植物生长的影响。通过对实验数据的分析，检测各参数相较于对照组的显著偏离，进而确定其无观察有害效应浓度（NOAEC，no-observed adverse effect concentration）。
