abstract = "Crop yields are highly depended on germination and early stages of plant growth. Numerous
priming techniques are being developed aimed to improve germination. Biopriming represents a
sustainable approach based on seed treatment in bacterial suspension of selected plant growth
promoting strains. One of the most promising plant growth promoting bacteria is Azotobacter
chroococcum. The aim of the research was to evaluate the effects of A. chroococcum F8/2 as a
biopriming agent on germination of various cultivable plants: basil, white mustard, cucumber,
tomato, wheat, canola, and soybean. After surface sterilization, seeds were bioprimed in the
bacterial suspension (107CFU/ml). Uninoculated seeds represented control treatment.
Germination test was conducted with 100 seeds per treatment and the germination was
monitored for 7 days. Following germination parameters were determined: germination
percentage, germination index, mean germination time, vigor I, vigor II, length and dry biomass
of the seedlings. The bacterial inoculation caused higher germination percentages of cucumber,
tomato, wheat and soybean. The highest increase in germination index was observed in wheat
(an increase of 19.8%). Tomato and basil were the only plants where vigor I was not increased
by inoculation. Generally, the most favorable effects of A. chroococcum biopriming were
observed in wheat where vigor I was increased more than twice, and vigor II was higher by
75.4% in inoculated seeds. The results indicate a significant potential for A. chroococcum use in
biopriming. The observed effects of seed priming on germination parameters were crop-specific,
with the most prominent potential in wheat biopriming.",
