摘　　要：为分析不同浓度氧化石墨烯(GO)对卷荚相思种子萌发和幼苗生长的影响,筛选合适的处理方式以提高良种播种品质,以该树种当年采收种子和贮存5年的陈种子为研究对象,设置不同GO浓度,分别为0(CK)、25、50、100、200、400和800 mg/L,测定其在不同处理下发芽率等萌发指标、幼苗株高等生长指标和可溶性糖等内含物质积累情况。结果表明,随着GO处理浓度的变化,卷荚相思种子的萌发指标、幼苗生长和内含物积累量呈现出不同的变化趋势。100 mg/L GO处理下新、陈种子发芽率和发芽势表现最佳;200mg/L GO处理下幼苗株高、鲜重、可溶性糖和总蛋白含量较CK增长幅度最高。综上,100~200 mg/L GO处理能够有效促进该树种新、陈种子发芽、幼苗生长和内含物质积累。本研究为卷荚相思良种繁育方法改进提供参考。In order to analyze the effects of different concentrations of graphene oxide(GO)on seed germination and seedling growth of Acacia cincinnata,and to screen suitable treatment methods to improve seeding quality of Acacia cincinnata varieties,the new seeds collected in the same year and the old seeds stored for 5 years were studied with GO concentrations of 0(CK),25,50,100,200,400 and 800 mg/L,respectively,and the germination rate,seedling height growth index and the accumulation of contents such as soluble sugar were measured under different treatments.The results showed that the seed germination index,seedling growth and inclusions accumulation showed different trends with the change of GO treatment concentration.The germination rate and germination potential of new and old seeds were the best under 100 mg/L GO treatment.The plant height,fresh weight,soluble sugar and total protein contents of seedlings under 200 mg/L GO treatment had the highest increase compared with CK treatment.In conclusion,100-200 mg/L GO treatment can effectively promote the germination,seedling growth and content accumulation of new and old seeds of this tree species.This study provides a reference for improving the breeding methods of Acacia cincinnata.
