In this paper, single-walled carbon nano- tubes (SWCNTs) and multi-walled carbon nano- tubes (MWCNTs) were found to accelerate leaf growth and development of rice seedlings at a low concentration (20 mg/L), accompanied with the increased chlorophyll content and net photosynthetic rate (P). Quantitative real-time polymerase chain reaction results indicated that both SWCNTs and MWCNTs significantly increased expression of genes associated with chloroplast development and cell sizes. Further analysis revealed that the abscisic acid content decreased and the gibberellin content increased while the content of [Formula: see text] and HO was slightly elevated and the activities of antioxidative enzymes (SOD, EC 1.15.1.1, and POD, EC 1.11.1.7) were differently modulated after treatment with the carbon nanotube (CNT). These results suggest a possible link between reactive oxygen species and plant hormones under CNTs treatment to promote rice seedlings growth.
在这项研究中，单壁碳纳米管（SWCNTs）和多壁碳纳米管（MWCNTs）在低浓度（20 毫克/升）下被发现能够加速水稻幼苗的叶片生长和发育，同时增加叶绿素含量和净光合速率（P）。实时定量聚合酶链反应结果表明，SWCNTs 和 MWCNTs 均显著增加了与叶绿体发育和细胞大小相关的基因的表达。进一步分析表明，脱落酸含量降低，赤霉素含量增加，而[Formula: see text]和 HO 的含量略有升高，碳纳米管（CNT）处理后抗氧化酶（SOD，EC 1.15.1.1 和 POD，EC 1.11.1.7）的活性也发生了不同的调节。这些结果表明，在 CNT 处理下，活性氧和植物激素之间可能存在联系，以促进水稻幼苗的生长。
