<i>Azotobacter chroococcum</i> F8/2: a multitasking bacterial strain in sugar beet biopriming

This study assesses the effects of Azotobacter biopriming on early development sugar beet. chroococcum F8/2 was screened for plant growth promoting characteristics and were estimated through germination parameters structural changes root tissues. A. characterized as a contributor to nitrogen, iron, potassium availability, well producer auxin 1-aminocyclopropane-1-carboxilic acid deaminase. Applied had reduced mean time by 34.44% increased vigor I 90.99% compared control. Volatile blend comprised 47.67% ethanol, 32.01% 2-methyl-propanol, 17.32% 3-methyl-1-butanol, trace 2,3-butanedione. Root micromorphological analysis bioprimed beet revealed considerable increase in primary, secondary xylem area, vessels size. Obtained results determine successful agent, active participant nutrient availability hormonal status modulation affecting vascular tissue.
