eflected in foliage damage and xylem cavitation, was relatively low under the moderate drought
of the second season, it did result in reduced growth increment the following (recovery) year.
Growth potential under favourable moisture regimes was nearly uncorrelated with drought
hardiness, suggesting that drought hardiness could be improved in this southwestern British
Columbia breeding population without negatively impacting growth potential in favourable
moisture conditions.

Abstract: Notes are provided on the biology, injuriousness and chemical control (carbaryl and
endosulfan are suggested) of Adelges cooleyi [Gilletteella cooleyi] on certain coniferous trees
[including Picea sitchensis, P. engelmannii, P. pungens and Pseudotsuga menziesii] in
Washington State.

Abstract: Pseudotsuga menziesii, Tsuga heterophylla and Picea sitchensis seeds were sown
in April 1971 in BC/CFS Styroblocks sizes 2 and 8 with volumes of 40 and 125 cmsuperscript 3
respectively. The seedlings in the larger containers were kept in a heated greenhouse for 2-3
months to stimulate growth to fill the containers, before joining those in the smaller containers in
an outdoor shadehouse nursery. Seedlings were planted out in British Columbia in March 1972. A
second trial was started in April 1972 and seedlings planted out in April 1973. Survival and ht.
growth were recorded for 5 growing seasons. The larger containers produced larger seedlings at
planting. There were n.s.d. in survival of seedlings grown in the different sized containers for all
3 species. The seedlings grown in the larger containers were significantly taller after the first
growing season in the field, a difference which persisted for the 5 seasons. Growing seedlings in
the larger containers was more expensive and the seedlings took longer to plant than those grown
in the smaller containers.

Abstract: Planting trials were established at sites within the Mountain Hemlock and montane
Coastal Western Hemlock biogeoclimatic zones. Six test areas were chosen within each zone.
Amabilis fir (Abies amabilis), noble fir (A. procera), yellow cedar (Chamaecyparis nootkatensis)
