Abstract

With the growing population and degrading environment, a new field of study is looking into the use of nanoparticles to enhance the quality and growth of crops, and to compensate for the sterilized soils. The present study was conducted to examine the effects of copper oxide nanoparticles (CuO NPs) on kale (Brassica oleracea) plant growth after treating its seeds with aqueous solutions with three concentrations of CuO NPs for 24 hours. The treated seeds were directly sown and the kale plants were harvested after 34 days. The results showed that the length of the roots and the shoots of the obtained kale were positively affected by the CuO NPs: larger increase came from the seeds treated with 70 ppm CuO NPs while both treated seeds by CuO NPs showed increased growth compared with the control sample. Moreover, the dry weight of the kale plants was also impacted by the treatment with CuO NPs: larger increase was produced from the seeds treated with 70 ppm CuO NPs relative to the control. This study shows that the application of CuO NPs at appropriate concentrations causes proliferation on the growth and development of kale.
纳米氧化铜对甘蓝生长的影响
随着人口的增长和环境的恶化,利用纳米颗粒来提高作物的质量和生长,并补偿土壤的无菌性是一个新的研究领域。本研究研究了三种浓度的氧化铜纳米颗粒(CuO NPs)水溶液处理甘蓝种子24小时后对甘蓝植株生长的影响。处理后的种子直接播种,34天后收获甘蓝植株。结果表明,CuO NPs对羽衣甘蓝根长和芽长均有显著影响,其中70ppm CuO NPs处理的羽衣甘蓝根长和芽长增幅较大,而CuO NPs处理的羽衣甘蓝根长和芽长均较对照有所提高。此外,羽衣甘蓝植株的干重也受到CuO NPs处理的影响:与对照相比,70ppm的CuO NPs处理的种子的干重增加更大。本研究表明,适当浓度的CuO NPs对羽衣甘蓝的生长发育具有增殖作用。
