evidence: To understand the impact of such electromagnetic radiations on plants, Capsicum annuum L. var. Pusa jwala was grown in the close vicinity of electromagnetic radiations emitted by Wi-Fi routers. [...] The seed germination in vicinity of Wi-Fi router was reduced to 75% and other growth related parameters like root and shoot length, leaf length, leaf width, leaf area index and fresh weight were significantly reduced. In Biochemical analysis, Chlorophyll pigments (Chl. a, b and total chlorophyll) were reduced by 4.8, 7.2 and 5.7 fold respectively and protein content reduced by 1.5 fold under influence of electromagnetic radiations. The product of lipid peroxidation (malondialdehyde) (18 fold) and proline content (10 fold) was increased synergistically. The electromagnetic radiations emitted by Wi-Fi router have negative influence on growth and biochemical response in Chilli plants.
