Abstract

To assess temporal dynamics of ectomycorrhizae (ECM) on red pine seedlings, numbers of ECM per gram of dry root were compared with temporal changes in seedling height, basalt diameter, above- and below-ground (coarse root) biomass, shoot:root ratio, and leaf water potentials. Three morphological types of ECM were observed. Temporal changes in numbers of total and brown-type ECM were significantly correlated with all seedling characteristics. The highest correlation (negative) occurred between field age of red pine seedlings and numbers of both total and brown-type ECM per gram dry root; high negative correlations also existed between basal diameter, total height of red pine seedlings, and numbers of total and brown-type ECM per gram dry root. Decreased average leaf water potential was observed to relate to increases in numbers of total and brown-type ECM. -from Authors
