Аннотация: The book deals with an old beech stand , oak and larch planted in group selection openings, under a crown canopy and an open area for the first three or four years.The purpose of the experiment was to test the possibility of bringing advance groups of European larch and oak on group selection openings in beech stands. In parallel experiments (mostly potted plants) the dry matter production of larch and beech was traced with growth analytical methods on the three plots and also on a smaller selection opening

Аннотация: Data on survival, stem height, stem volume and yield per hectare from a provenance trial with Scots pine (Pinus sylvestris) at Nordanas, lat 64 grad. 19', long 18 grad. 09', alt 400 m, are presented in this report. Regression analyses were carried out to test the influence of transfer on the parameters studied. For the most important characteristics, yield per hectare and survival, it was found that a transfer by 1-2 latitudes southward will imply an improvement. Since the progenies from individual trees within thepopulations were kept apart the variation within populations could be analysed. This variation was found to be considerable both for survival and height in some of the populations.

Аннотация: By means of results from provenance trials in northern Sweden, a map of severity index for various latitudes and altitudes was drawn up. The severity index is defined as the expected percentage plant mortality rate in the local population during the first 20 years after establishment of the plantation. By combining transfer effects based on data from all trials, a general trend of the transfer effect was calculated. The regression obtained showed that, at constant altitude, each degree of transfer southwards meant an increase of survival of 10.8 percentage units; at constant latitude, every 100 metres of downward transfer implied an increase in survival of 3.0 percentage units.Optimum transfer is defined as the transfer giving maximum volume yield, which equals 70-80 per cent survival.
