Scientists in the Indian state of Gujarat selected two types of plants to study, spinach and tulsi. Tulsi is also known as Holy Basil. They raised the plants, feeding them water and nutrients, and controlled the temperature of the lab. The plants were also exposed to electromagnetic waves at 900MHz at a strength of 1.9 milli tesla for 72 hours.
The findings from the study showed morphological changes in the growth rate of the plants. Height, as well as the growth in the number of branches or leaves were stunted. The leaves were smaller and protein content was lower as well.
As there are no standards about Specific Absorption Rate (SAR) for plants, it is difficult to gauge what this experiment really proves. Zapping anything with direct radiation, even in small amounts continuously is going to leave a mark if watched closely enough. It may provide some guidance about broader environmental factors and how they are influenced by electromagnetic radio waves emitted by cell towers or power lines.
