Abstract:

The influences of different concentrations of ASP and SMZ-TMP on seed germination of soybean (Glycine 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 pretreatment, while scavenger enzymes were increased. Seed protein and amino acid content were increased by SMZ-TMP soaking pretreatment.
