The use of nanoparticles (NPs) in agricultural fields has risen to a level where people are considering NPs as an alternative to commercial fertilizers. The input of copper oxide NPs (CuO NPs) as seed primers was investigated in this study, and the growth indices of such as phenotypic parameters, photosynthetic attributes, and biochemical parameters were measured during maximum vegetative growth stage, i.e., at 45 days after sowing. Surface sterilized seeds were soaked in varying concentrations (0, 2, 4, 8 and 16 mg/L) of CuO NPs for 15, 30, and/or 45 min. After those priming periods, the seeds were planted in pots and allowed to grow naturally. Among the different tested concentrations of CuO NPs, 4 mg/L of CuO NPs for 30 min seed priming proved to be best, and considerably increased the, shoot length (30%), root length (27%), net photosynthetic rate (30%), internal CO concentration (28%), and proline content (41%). Besides, the performance of the antioxidant enzymes, viz, superoxide dismutase, catalase, peroxidase, and biochemical parameters such as nitrate reductase and carbonic anhydrase were also increased by several folds after the application of CuO NPs in . The present study suggests that CuO NPs can be effectively used to increase the performance of and may also be suitable for testing on other crop species.
纳米颗粒（NPs）在农业领域的应用已发展到人们将其视为商业肥料替代品的程度。本研究考察了作为种子引发剂的氧化铜纳米颗粒（CuO NPs）的投入情况，并在最大营养生长阶段，即播种后45天，测量了诸如表型参数、光合属性和生化参数等生长指标。将表面灭菌的种子浸泡在不同浓度（0、2、4、8和16毫克/升）的CuO NPs中15、30和/或45分钟。经过这些引发处理后，将种子种植在花盆中并任其自然生长。在不同测试浓度的CuO NPs中，4毫克/升的CuO NPs进行30分钟种子引发被证明是最佳处理，显著增加了茎长（30%）、根长（27%）、净光合速率（30%）、胞间CO浓度（28%）和脯氨酸含量（41%）。此外，在应用CuO NPs后，抗氧化酶（即超氧化物歧化酶、过氧化氢酶、过氧化物酶）的活性以及诸如硝酸还原酶和碳酸酐酶等生化参数也提高了数倍。本研究表明，CuO NPs可有效用于提高[作物名称未明确]的性能，也可能适用于其他作物品种的测试。
