Abstract

Investigations have been made since 1946 on the degree of attack on thinning plots in 2 stands of Norway Spruce planted in (a) 1893 and (b) 1907 and one of Sitka Spruce (c) planted in 1905-12. An examination of the stumps showed that on plot (a) the degree and extent of attack increased with...

Abstract

In trials at Vorwerksbusch (Reinbek) careful hoeing nearly doubled the height and diameter of 1-year rooted cuttings of Populus 'Bachelieri Wolfgang'. Treatment of Salix viminalis X S. purpurea beds on sandy loam with marl, marl containing Mg, and basic foundry slag (crude CaSiO3) revealed no clear ...

Abstract

Trials with cuttings of Populus 'Manitobensis' of lengths 2, 5, 10, 15, 20, 25 and 30 cm., and diameters 3-5, 5-7, 7-9 and 9-12 mm., showed that longer cuttings gave stronger plants, and that under average conditions the 2-cm. cuttings soon died. A definite relation was found between height...

Abstract

A biometric investigation, with the following conclusions. Root-collar diameter of the seedlings varies linearly with height, the slope of the line being dependent on age and site and independent of seedling density. The annual change in this slope for a given population indicates which dimension...

Abstract

A study was made on Populus tremuloides (a) and P. grandidentata (b) root suckers. On the whole, (a) suckered nearer the soil surface and from smaller roots than (b), which occupies the whole A horizon more completely. This difference probably accounts for the advantage of (b) over (a) on shallow...
