Relation of Crown and Foliage Traits to Height Growth of Sitka Spruce

Autor: W. H. Pawuk, D. L. Copes, W. A. Farr, R. R. Silen

Publikováno v: Western Journal of Applied Forestry. 11:77-80

Four crown and foliage traits of a young Sitka spruce (Picea sitchensis) stand were tested with rooted cuttings in greenhouse and field plots for possible thinning selection guidelines. Repeatability estimates of the amount of genetic control over th

Effects of Douglas-fir parentage on Swiss needlecast expression

Autor: R. R. Silen, N. L. Mandel, E. E. Nelson

Publikováno v: Forest Pathology. 19:1-6

Densities of pseudothecia on Douglas-fir needles infected with Phaeocryptopus gaeumanni and needle retention on Christmas trees were related to male and female parentage in a 4 by 5 factorial mating in replicated plantings in western Oregon. Interact

The development of genetic variances in height growth of Douglas-fir over a 53-year period is analyzed and found to fall into three periods. In the juvenile period, variances in environmental error increase logarithmically, genetic variance within po
