MEASUREMENT OF THE DYNAMICS OF ROOT GROWTH BY THE ALLIUM NEST
Was developed photographic method for measuring the dynamics of root growth in the continuous experiment using Allium test in environmental monitoring (presence of mutagens) and determining the activity of cytotoxic drugs. Accuracy of the method was evaluated. It was shown that the accuracy of measurement of the root growth in growth is 10 %. Evaluation of the accuracy of measurement is statistically significant and it is tested on a large number of experimental data in assessing the dynamics of root growth under normal conditions and under the influence of various chemical compounds. Were tested, and salts of heavy metals, cytotoxic agents (such as methotrexate). It is shown that the proposed method gives a lower error in determining the dynamics of root growth in the experiments involving the use of environmental monitoring and pharmacology, as compared to the previously described methods.
