The application of nanomaterials in different plants exerts varying effects, both positive and negative. This study aimed to investigate the influence of carbon nanoparticles (CNPs) on the growth and development of Bur. plant. The morphological characteristics, photosynthetic parameters, and chlorophyll content of F. tikoua Bur. plants were evaluated under four different concentrations of CNPs. Results indicated a decreasing trend in several agronomic traits, such as leaf area, branching number, and green leaf number and most photosynthetic parameters with increasing CNPs concentration. Total chlorophyll and chlorophyll b contents were also significantly reduced in CNPs-exposed plants compared to the control. Notably, variations in plant tolerance to CNPs were observed based on morphological and physiological parameters. A critical concentration of 50 g/kg was identified as potentially inducing plant toxicity, warranting further investigation into the effects of lower CNPs concentrations to determine optimal application levels.
纳米材料在不同植物中的应用会产生不同的效果，既有正面的也有负面的。本研究旨在探究碳纳米颗粒（CNPs）对 Bur. 植物生长发育的影响。在四种不同浓度的 CNPs 下，评估了 F. tikoua Bur. 植物的形态特征、光合参数和叶绿素含量。结果表明，随着 CNPs 浓度的增加，几个农艺性状（如叶面积、分枝数和绿叶数）和大多数光合参数呈下降趋势。与对照相比，暴露于 CNPs 下的植物的总叶绿素和叶绿素 b 含量也显著降低。值得注意的是，根据形态和生理参数观察到植物对 CNPs 的耐受性存在差异。50g/kg 的临界浓度被确定为可能诱导植物毒性的浓度，需要进一步研究较低浓度的 CNPs 的影响，以确定最佳应用水平。
