Abstract

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. The seeds treated with antibiotics active against Gram positive organisms were deficient in both carbohydrates and proteins. The seeds treated with antibiotics active against Cram negative organisms had a delayed germination but a normal physiological development. Streptomycin had the most adverse effect on translocation but stimulated germination. Analysis of variance of germination indicated that seed germination was dependent upon the antibiotic used. The analysis for the translocation resulted in the means being significantly different. No adverse effects, caused by the soil treatment, were noted for germination. Neomycin, penicillin, and streptomycin appear to stimulate germination; tyrothricin and polymyxin inhibit germination the first week but by the second week have a higher germination percentage than the control. Streptomycin, polymyxin and neomycin drenches have the most beneficial effect on the growth of Nato, Magnolia, and Upland varieties. A trigger agent is apparently released which stimulates growth from the first week until termination of the experiment. The three antibiotics inhibit the growth of Blue bonnet.
