Effects of Ciprofloxacin Hydrochloride on Early Growth and Development of Glycine max(L.)Merr.
Objective:To investigate the toxic effects of residual ciprofloxacin hydrochloride antibiotics on crop growth and development.Methods:The paper set up a series of concentration gradients of ciprofloxacin hydrochloride to explore its impact on the early growth of Glycine max(L.)Merr..Results:The germination rate,germination index and vigor index of soybean decrease with the increase of reagent concentration in the range of 0～100 mg/L.When ciprofloxacin hydrochloride concentration is 5 mg/L,the germination potential is the highest,and there is no significant difference compare with the control group,but when ciprofloxacin hydrochloride concentration is more than 5 mg/L,the germination potential decrease with the increase of concentration.Within 96 hours,the total length of soybeans in 5 mg/L group is higher than that other groups,but decrease with increasing ciprofloxacin hydrochloride concentration over time.The inhibitory effect of 100 mg/L is the most significant,with the shortest total length.Compare with the control group,the fresh weight and various chlorophyll contents of seedlings decrease with the increase of ciprofloxacin hydrochloride concentration.Conclusion:High concentrations of ciprofloxacin hydrochloride in the environment can inhibit the germination and early growth and development of soybeans.
