Interference of resistance inducers on the physiological and sanitary quality of beet root seeds and seedlings

High physiological and sanitary quality seeds and seedlings, resulting in a uniform and pathogen-free plant, require further study of possible approaches to improve seed potential, tolerance, and resilience, including the use of resistance inducers.This study aims to determine how different resistance inducers affect the physiological performance and sanitary quality of seeds and seedlings of beetroot (Beta vulgaris L.).The treatment of beet seeds was carried out with a control group (distilled water), Bacillus amyloliquefaciens, and Trichoderma harzianum.Germination, seedling length, dry mass, seed health, protein quantification in plant tissues, and phenylalanine ammonia-lyase activity were all assessed.The resistance inducers had no adverse effects on the physiological potential of seeds treated with all evaluated inducers.Regarding the sanitary quality of seeds, beet seed treatments with Bacillus amyloliquefaciens doses of 3.0 and 6.0 mL L -1 of and Trichoderma harzianum doses equal to or greater than 0.125 mL L -1 significantly reduced the incidence of Fusarium sp.Only the Trichoderma harzianum treatment reduced the incidence of preemergence Damping off at all doses tested.A significant effect was observed in reducing total protein contents in seeds treated with Bacillus amyloliquefaciens and Trichoderma harzianum.
