Data product containing 16-year tree heights, survival, and genetic variation for "Genetic Variation in Blue Spruce: A Test of Populations in Nebraska"
In the fall of 1969 seeds were collected from more than 400 trees throughout the natural range of blue spruce (Wyoming, Utah, Colorado, Arizona, and New Mexico). These seeds were sown in a nursery in Michigan in 1970. In 1973 over 800 of those seedlings were planted in a plantation in Horning, Nebra...

| الملخص: | In the fall of 1969 seeds were collected from more than 400 trees throughout the natural range of blue spruce (Wyoming, Utah, Colorado, Arizona, and New Mexico). These seeds were sown in a nursery in Michigan in 1970. In 1973 over 800 of those seedlings were planted in a plantation in Horning, Nebraska. This dataset contains annual tree heights of surviving trees from 1973 to 1988. Other measurements recorded through this time period include tree vigor, frost injury, crown spread diameters, foliage color, as well as tree color.<br>The objective of this research was to identify seed sources for use as a windbreak in the Great Plains, environmental improvements, and for esthetic plantings.<br>Original metadata date was 10/11/2006. Metadata modified on 03/11/2013 to adjust citation to include the addition of a DOI (digital object identifier) and other minor metadata edits. Additional minor metadata updates on 12/01/2016. |
