Goss, R.W. (1960) Mycorrhizae of Ponderosa pine in Nebraska grassland soils (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 192)
Abstract
While the genus Pinus has been the subject of extensive mycorrhizal studies there are only a few scattered references to western yellow pine, P. ponderosa, and no detailed descriptive literature on the mycorrhizae of this species. P. ponderosa is indigenous to Nebraska and the one species most extensively grown in local nurseries for windbreaks and farm plantings. Similarly, there is little information on mycorrhizae in the Great Plains between the forested regions of the Mississippi River states and the Rocky Mountains. Because this predominantly grassland area is sparse in natural tree growth the individual tree as an ornamental or in groups as windbreaks becomes of great importance. Under the diverse soil conditions, and with relatively low rainfall and high evaporation and transpiration rates, the survival of transplants is relatively low. The possible role of mycorrhizae in influencing the survival rate has never been investigated in Nebraska. The present study was undertaken to determine in a preliminary way the occurrence and significance of mycorrhizae on the production and survival of ponderosa pine in virgin grassland soils.
