Can Lateral Root Characteristics Be A Majorfactor In Assessing Seedling Quality

A grading standard for tree seedlings should be an easily observed or measured characteristic that is strongly indicative of performance after outplanting. Lateral root morphology may be such a characteristic. Recent work with sweetgum indicates that at least four strong lateral roots may be needed to make a seedling competitive for artificial regeneration. Tests with scores of half-sib seedlots indicate that at least 40 percent of the nursery seedlings produced may not have this number of lateral roots developed when they are lifted for planting.
