Cytological studies revealed irregularities in the nuclear life cycle of Inonotus tomentosus. The mycelia was multinucleate and the nuclei were found in groups of two to six. By the time the nuclei reached the subhymenium ...

Radial and axial variations of tracheid length, specific gravity, ring width, and latewood percentage were studied from the stems of a dominant and a suppressed tamarack tree. The trees were 81 and 83 years old respectively, ...

This study was the -first study designed specifically to analyse the competitive effects of density and species mixture for both Pinus banksiana and Populus tremuloides seedlings during the initial stages of growth and ...

Multivariate phytosociological methods were used to investigate the ecology of upland boreal forest stands. The ecological information was used to derive silvicultural recommendations. The boreal forest stands did not ...

The objectives were: to review the successional behaviour of white spruce (Picea glauca (Moench) Voss) - trembling aspen (Populus tremuloides Michxt) stands in the literature, to conduct field studies of the successional ...

Genetic and environmental variance in cone and seed properties and early progeny growth of Picea mariana (Mill.) B.S.P. clones were evaluated using cones and seed from two to three ramets of 19 clones each growing in a ...

Several genera of bacteria were isolated from the foliage, twigs, bark and wood of stems of chlorotic 10 - 12 years old white spruce (Picea glauca (Moench) Voss). Most of the isolates were nonspore-forming, aerobic ...

The competitive relationship between jack pine (Finns banksiana Lamb.) and trembling aspen (Populus tremuloides Michx.) was studied in an 8-year-old mixed stand in North Central Ontario, Canada. During the summer of 1984, ...

The contribution of individual branches to the current annual xylem increment of the main stem of six young red pine (Pinus resinosa Ait.) was investigated. Logical estimates of branch productivity including: branch ...
