Tobacco (Nicotiana tabacum) black shank disease, caused by Phytophthora nicotianae, is a significant threat to tobacco crops, leading severe economic losses. Prolonged use of agrochemicals control this disease has prompted the exploration eco-friendly biological strategies. This study investigated effects Trichoderma harzianum, biocontrol agent, on N. tabacum in comparison P. focusing growth, biomass, root morphology and anatomy, hormonal changes, osmotic regulation. T. harzianum significantly enhanced plant biomass accumulation, system development, physiological attributes such as photosynthetic pigment levels antioxidant enzyme activity. In contrast, nicotianae negatively impacted these parameters, inhibiting growth function. Notably, increased proline content induced resistance mechanisms, mitigating stress promoting overall health. These findings highlight potential sustainable solution for managing while improving crop productivity.

Rhizosphere Growth-Promoting Fungi of Healthy Nicotiana tabacum L.: A Systematic Approach to Boosting Plant Growth and Drought Resistance

Microorganisms, Journal Year: 2025, Volume and Issue: 13(3), P. 543 - 543

Published: Feb. 27, 2025

Drought, exacerbated by global warming, poses a significant threat to crop growth and productivity. This study identified strain of Trichoderma harzianum from the rhizosphere healthy Nicotiana tabacum L. plants evaluated its role in enhancing drought tolerance. The isolated effectively colonized plant roots promoted N. To investigate potential, T. was inoculated into under varying conditions, impact on growth, physiological responses, resilience assessed. Comprehensive analyses agronomic traits, parameters, enzyme activities, photosynthetic performance, osmoprotectant levels, membrane lipid peroxidation revealed that inoculation (light with harzianum, moderate severe treatments) systematically improved development resistance. These findings provide valuable insights lay foundation for developing innovative biofertilizers enhance tolerance sustainability.
