*2.3. Measurements of Growth Parameters*

All plants were harvested at the end of the test, and then, plant heights, root lengths, and fresh biomasses of 10 plants from each treatment were measured and recorded. The growth inhibition rate was calculated using following formula:

$$\% \text{ inhibition} = (\mathsf{M}\_0 - \mathsf{M}\_t) / \mathsf{M}\_0 \times 100$$

where M0 indicates the measurement of the control treatment and Mt indicates the measurement of the antibiotic treatment.
