Background: Zinc is one of the essential micronutrients in plants required in very low
quantity for plant growth and development. In higher concentration, it is known to to
reduce the rate of photosynthesis, So homoeopathic preparations tested to see it role
on plan growth.
Objective: To analyse the effect of homoeopathic preparation of Zinc sulphate on
plants through in‑vitro assay using Bacopa monnieri as a model plant system.
Materials and Methods: Six homoeopathic potencies (1X to 6X) of Zinc sulphate
were used on a decimal scale along with the control (MS basal agar medium). The
samples were evaluated by adding fixed amount (100 μl) in the media as well as by
dipping the explants in the test sample overnight. At the completion of the incubation
period (14 days) the fresh and dry weight, number and length of the roots, number and
length of the shoots and the number of leaves were analysed.
Results: It was observed that Zinc sulphate showed growth inhibition at potencies
from 1X to 5X, whereas at potency 6X, it exhibited growth promotion effect, when
compared with the control.
Conclusion: Homoeopathic drug (Zinc sulphate) exhibited growth promotion at higher
potency (6X) and growth inhibition at lower potencies (1X to 5X) on Bacopa monneiri. |
