Photosynthetic efficiency of frozen-stored Picea glauca seedlings in relation to root pruning, root growth, and shoot moisture stress / by S. J. Colombo. --
(1981)
This study examines the influence of duration of frozen
storage (-2 C) and root pruning on photosynthetic efficiency,
shoot moisture stress and root growth of white spruce (Picea
glauca (Moench) Voss) seedlings planted ...

Indices of branch contribution to bole growth in Pinus resinosa Ait.
(1982)
The contribution of individual branches to the
current annual xylem increment of the main stem of six

Mating system and population structure in a black spruce (Picea mariana (Mill.) B.S.P.) clonal seed orchard in Northwestern Ontario
(1985)
Multi-locus enzyme systems were studied in a black
spruce {Picea maniana (Mill.) B.S.P.) clonal seed orchard in
northwestern Ontario. The embryonic and megagametophytic
tissues of each clone were sampled and ...
