Researchers have shown that graphene oxide has a significant effect on plant and pathogen growth and development. To better understand the effect of graphene oxide on the resistance of Brassica napus L. to Sclerotinia sclerotiorum, Zhongshuang 11 was used to evaluate changes in the morphology and physiology after graphene oxide treatment. Detached leaf inoculation was used to detect S. sclerotiorum infection in rapeseed. The results indicated that treatment with a low concentration of graphene oxide had no significant effect on the growth of B. napus "Zhongshuang 11." Graphene oxide inhibited S. sclerotiorum in PDA medium. Treatment with 15 mg/L graphene oxide for 8-24 h in seeds and 8-16 h in seedlings suppressed S. sclerotiorum growth compared to the control samples. These results demonstrate that a low concentration of graphene oxide did not harm the growth of B. napus but did enhance its resistance to S. sclerotiorum.
研究人员已经表明，氧化石墨烯对植物和病原体的生长发育有显著影响。为了更好地理解氧化石墨烯对甘蓝型油菜抗核盘菌能力的影响，选用中双11来评估氧化石墨烯处理后其形态和生理的变化。采用离体叶片接种法检测油菜中的核盘菌感染情况。结果表明，低浓度氧化石墨烯处理对甘蓝型油菜“中双11”的生长没有显著影响。氧化石墨烯在PDA培养基中能抑制核盘菌生长。与对照样品相比，在种子中用15mg/L氧化石墨烯处理8 - 24小时以及在幼苗中处理8 - 16小时可抑制核盘菌生长。这些结果表明，低浓度氧化石墨烯不会损害甘蓝型油菜的生长，但会增强其对核盘菌的抗性。
