Abstract
Flax ( Linum usitatissimum L.) accumulates Mn and develops Mn toxicity symptoms when grown on certain soils low in available Fe. Application of FeEDDHA decreases Mn accumulation and eliminates Mn toxicity symptoms in such cases. This greenhouse study compares the susceptibility of four closely related flax lines (Differentials 1, 3, 16, and 17) used in rust ( Melampsora lini ) studies, to Mn toxicity and the response to soil‐applied FeEDDHA. Differential 3 showed the most response to the added chelate. A preplant soil application of 2 ppm FeEDDHA‐Fe eliminated the lower leaf scorch presumably associated with Mn toxicity, increased total dry matter yield and Fe accumulation, and decreased Mn accumulation in above‐ground parts of all four lines. However, dry matter yield of Differential 3 was increased 81% after 64 days as compared to 27, 18, and 33% for Differentials 1, 16, and 17, respectively. Genotype, either in the presence or absence of FeEDDHA, had little effect on Mn and Fe concentration, indicating factors besides uptake and concentration of these ions are responsible for the poor growth of Differential 3 in certain soils low in available Fe. Phosphorus and Zn concentrations were not apparently related to the greater susceptibility of Differential 3 to Mn toxicity.
