- Abstract:
- The vascular connections between stems and roots of 45 year old red maple (Acer rubrum L.) stump sprouts were investigated to determine the effect on diameter growth of removing all but one sprout per clump. Dye applications through the sprouts and the roots helped reveal the connections. It was determined that, in general, the remaining stem could use all or almost all of the clump's root system, but gypsy moth caterpillar damage prevented a comparison of increment growth rates between stems which were only crown released and those which also had more root area available. The effect of pressure gradients on xylem sap flow as it relates to this study is discussed, as is cambial reorientation. The ages of the roots of one sprout clump were estimated in order to compare them with root growth habits and with sprout ages. Management implications are outlined.
