Re-evaluating the Significance of the First-order Lateral Root Grading Criterion for Hardwood Seedlings

  title={Re-evaluating the Significance of the First-order Lateral Root Grading Criterion for Hardwood Seedlings},
  author={Douglass F Jacobs and John R. Seifert},
—Numerous authors have reported on the importance of the number of firstorder lateral roots (FOLR) when evaluating the morphological quality of nursery hardwood seedlings. Studies have shown that seedlings with a greater quantity of FOLR outperform seedlings with a lesser quantity of FOLR in the field. However, the FOLR measure may be limited in its ability to quantify root system morphology. Additionally, the number of FOLR is correlated with other morphological characteristics, and few… CONTINUE READING
