Genetic variation and productivity of Populus trichocarpa and its hybrids. IX. Phenology and Melampsora rust incidence of native black cottonwood clones from four river valleys in Washington
Autor: J.M. Dunlap, R.F. Stettler
Publikováno v: Forest Ecology and Management. 87:233-256
A common-garden study of Populus trichocarpa Torr. and Gray was initiated in 1985 when material from 128 trees was collected along two mesic (Hoh and Nisqually) and two xeric (Dungeness and Yakima) river valleys. In spring 1986 cuttings were used to

Genetic variation in red alder (Alnusrubra) in relation to native climate and geography
Autor: P.E. Heilman, R.F. Stettler, A.A. Ager
Publikováno v: Canadian Journal of Forest Research. 23:1930-1939
Genetic variation was examined within and among populations of red alder (Alnusrubra Bong.) from elevational gradients in four river drainages of the Pacific Northwest. Wind-pollinated progenies of 120 trees were grown for 3 years in a common garden

Genetic variation and productivity of Populustrichocarpa and its hybrids. V. The influence of ramet position on 3-year growth variables
Autor: J.M. Dunlap, R.F. Stettler, P. E. Heilman
Publikováno v: Canadian Journal of Forest Research. 22:849-857
A 3-year study was conducted on the effects of different stem positions (from which cuttings were taken on a stool-bed ortet) on sprouting characteristics and stem growth of Populustrichocarpa Torr. & Gray. In 1986 ramets were collected from five ste

Genetic improvement and evaluation of black cottonwood for short- rotation biomass production. Final report, 1987--1992
Autor: H. D. Bradshaw, T. M. Hinckley, P.E. Heilman, R.F. Stettler
This project was initiated in 1978 to serve three objectives: (1) develop genetically improved poplar cultivars offering increased productivity under short-rotation culture; (2) identify the major components of productivity in poplar and determine wa
