Abstract
This study investigated the biochemical changes in chilli plants resistant or susceptible to bacterial wilt, caused by Ralstonia solanacearum, following inoculation and treatment with copper hydroxide. Treated inoculated plants exhibited significant increases in ionic contents, including phosphorus (3.25%), nitrogen (8.98%), and micronutrients such as potassium, magnesium, zinc, calcium, and copper. Enhanced biochemical parameters were observed, including chlorophyll (80.78 µmol), peroxidase (2.22 µg/g), catalase (4.10 µg/g), hydrogen peroxide (3.30 µg/g), total phenolic compounds (14156.61 µg/g), superoxide dismutase (4.13 µg/g), total soluble proteins (3.87 µg/g), and total soluble sugars (3.17 µg/g), compared to untreated inoculated plants. These results highlight the biochemical alterations linked to disease resistance and offer insights for developing effective formulations to combat bacterial wilt in chilli.
