Genetic variation of wood properties in balsam poplar (Populus balsamifera L.)
(1995)
Genetic variation in wood properties among and within three provenances
of balsam poplar was investigated. Between 1982 and 1984, clonal populations
were sampled along the Longitude 9QOW in North Wisconsin (Lat. 45°N ...
Effects of post-budset fertilization on second-crop black spruce container stock
(1992)
Second crop black spruce (Picea mariana (Mill.) B.S.P.) container
