Influence of Aluminum Ions on Developmental Morphology of Sugarbeet Roots

High concentrations of aluminum in low pH soils are toxic to sugarbeet (Beta vulgaris L.). In a test to determine the effect of increased concentrations on seedling development, 4, 8, and 12 ppm Al nutrient culture caused significant reduction of root and hypocotyl growth. The primary root curved and the root cap broke away. Lateral roots emerged as small outgrowths on the primary root axis and developed abnormally. Anatomical examination of primary and lateral roots revealed extraneous material in the apical meristem, root cap, and cortical region. Apical regions of the primary and lateral roots did not exhibit their typical organization and cells divided in an irregular pattern. Aluminum can be an important factor in the suppression of sugarbeet growth in acid soils.
