Book Description
S2Black cherry is one of the most valuable eastern hardwoods, but guides for choosing suitable seed sources for planting stock are limited. After 14 years, survival of 8 of 24 sources planted is greater than 70 percent, and there are no significant differences in height. These sources offer the greatest potential for planting in northwestern Pennsylvania; they include four Pennsylvania sources and one each from Tennessee, West Virginia, Ohio, and Virginia. Although these planted trees survived and grew satisfactorily, they did not grow better than nearby natural seedlings. If natural seedlings are available, the need or desirability of planting is questionable.S3.
