Abstract:
Taking seeds of Zinnia elegans as experimental materials,0(CK),100 mol/L,200 mol/L,300 mol/L,400 mol/L and 500 mol/L concentrations of penicillin solution were respectively made as treatments to soak the seeds.Germination indexes (the germination energy,germination rate,germination index and vitality index) and the growth indexes (shoot length,root length,fresh weight and amount of lateral roots) of seedlings were measured during seed germination to find the effects of penicillin on seed germination and the seedling growth of Zinnia elegans.The results showed that,all of the indexes increased and then decreased with the increasing of penicillin solution.200 mol/L and 300 mol/L concentrations of penicillin solution could enhance the germination energy,germination rate and vitality index significantly.All of the treatments could significantly promote root length and fresh weight of seedlings.300 mol/L concentration of penicillin solution had very significant role in promoting all of the germination indexes and seedling growth indexes except the germination rate.This showed that certain concentration of penicillin solution had promotive effect on seed germination and the seedling growth of Zinnia elegans,and the most suitable concentration was 300 mol/L.
