摘要
以大豆(Glycine max)种子为材料,用不同浓度的阿斯匹林和复方新诺明水溶液,在(20±1)℃条件下分别浸种24 h和12 h,测定大豆种子萌发过程中的各项生理生化指标以及萌发后的各形态指标。实验结果表明:阿斯匹林和复方新诺明水溶液浸种都能有效地提高大豆种子的发芽率和活力指数,还能促进大豆根系的生长。其中以62.5 nlg·L-1的阿斯匹林和0.5 mg·L-1的复方新诺明处理后的效果最为显著。阿斯匹林浸种能使大豆萌芽的相对电导率显著降低,使活性氧清除酶的活性有所提高。复方新诺明浸种则使大豆萌芽的蛋白质含量以及氨基酸总量都有显著的提高。
The influences of different concentrations of ASP and SMZ-TMP on seed germination of soybean ( dycine max ) were studied. The results indicated that the germination percentages, vigor index and root development were increased by presoaking the seeds in ASP and SMZ-TMP solutions. The optimal concentrations of ASP and SMZ-TMP soaking solutions are 50 mg· L-1 (24 h) and 62.5 mg·L-1(12 h), respectively. The results also showed that, the relative conductivity of soybean seedlings was decreased by ASP soaking pretreat-ment, while scavenger enzymes were increased. Seed protein and amino acid content were increased by SMZ-TMP soaking pretreatment.
