and effects on the remaining plant traits were determined in greenhouse experiments. We applied a screening-level phytotoxicity assay to evaluate the effects of 10 antibiotics (at concentrations ranging from 1 to 10,000 μg/L) on germination and early plant growth using three plant species: lettuce (Lactuca sativa), alfalfa (Medicago sativa), and carrot (Daucus carota).
This report is concerned with the effect of antibiotics on germination and translocation of native chemicals in the laboratory and on the plant's reaction to certain antibiotics used as soil drenches under greenhouse conditions. (Figure 1, 2 and 3).
D. carota was the most sensitive plant species, often by an order of magnitude or more, followed by L. sativa and then M. sativa. endobj 84 0 obj

The range of phytotoxicity of the antibiotics was large, with EC₂₅s ranging from 3.9 μg/L to >10,000 μg/L.
The effects of each antibiotic concentration on the germination frequencies of seeds selected by the stepwise option are shown in Fig. 0000014768 00000 n

In all the cases, the antibiotics caused a delay in the germination frequencies of seeds, showing a phytotoxic action on crop growth.
Specifically, seed germination and root elongation kinetics, as well as the number of mithotic figures in root apical meristem, were studied in relation to different concentrations of each antibiotic (0, 0.1, 1, 10, 100, 1000 mg L −1) for 10 and 7 days, respectively. 0000002200 00000 n

Abstract. Chlortetracycline, levofloxacin, and sulfamethoxazole were the most phytotoxic antibiotics.
