Physiological and Nutritional Responses to Ozone Application in Tomato Seedling Plants

Research on environmentally friendly techniques for the agroindustry is growing constantly. In this sense, supply of ozone (O3) has been taken into consideration, especially disinfection because its high oxidizing power. However, there not enough information about application dissolved O3 via fertigation in crops. For that reason, study, two trials were carried out simultaneously to determine consequences plant growth and quality tomato plants. The first trial aimed assess effects fertigated with nutrient solution O3. second was performed establish ideal rate both experiments, we measured biometric, physiological, nutritional parameters plant. results obtained showed treatment resulted highest overall dry weight gain, whereas decreased leaf proline total soluble sugars concentrations. There no clear effect chlorophyll plants under application. Regarding parameters, led a higher content P K These findings indicate use may present several advantages plants’ quality.
