Scientists Speed Up Tree Growth in N.C. ABCNews

Scientists say they have found a way to boost tree growth but so far there they haven’t found a practical use for the fast-growing plants. A tree species at N.C. State’s Upper Piedmont Research Station in Reidsville grew up to 20 feet in a single year, about double its usual rate. A typical tree in the area grows about 18 inches in a good year.
