The Effect of Seed Origin on Drought Resistance of Green Ash in the Prairie-Plains States
Abstract:Success of forest planting in the Prairie-Plains region is, among other things, dependent upon the use of drought resistant trees. The authors tested artificially the drought resistance of green ash seedlings grown from seed collected in 39 separate localities of the region. Seed from the northwest portion of the region produced the most dronght resistant plants, while plants from southern and eastern seed were least resistant. Differences were also noted in size of seedling, color of foliage, and time of resumption of growth in the spring. All of these differences indicate the existence of climatic races within the species.
