Versuche zur Einbringung von Larche in Buchenbestande
[Text] : монография / B. Lupke ; Universitat Gottingen. - Frankfurt am Main : J.D. Sauerlander's Verlag, 1982. - 123 s. : рис., табл. - (Schriften aus der Forstlichen Fakultat der Universitat Gottingen und der Niedersachsischen Forstlichen Versuchsanstalt, ISSN 0344-5666 ; 74). - ger. - Библиогр.: с. 114-123. - ISBN 3-7939-5074-3 : 5.10 р.
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

Nur Individuenauswahl oder auch Gruppenauswahl?
[Текст] : zu W. Fleders "Erziechungsgrundsatze fur Buchenbestande" / D. Mulder. - Frankfurt am Main : J.D. Sauerlander's Verlag, 1990. - 53 с. : рис. - (Schriften aus der Forstlichen Fakultat der Universitat Gottingen und der Niedersachsischen Forstlichen Versuchsanstalt, ISSN 0344-5666 ; 96). - ger. - Библиогр.: с. 51-53. - ISBN 3-79-39-5096-4 : 5.00 р.
Аннотация: With one exception German thinning rules have always been aimed at selecting individuals of desirable properties and removing one by one their surrounding neibours even if these are just as valuable. In the framework of this approach a symmetrical crown-extension of the prospective crop trees is a major concern. All this amounts to a "spacing thinning". As opposed to selection thinnings which enforce upon heterogeneous stands very schematic ditribution patterns, group thinnings allow for a much more flexible adaptation to the special conditions of each stand when entering thinning age. - Some preparatory comments were made on the question to what extent other tree species and other constellations offer themselves for group thinnings. One can hope that the specialists of growth science and wood technology will now put the assumptions on which selection thinning and group thinning are based to a vigorous test
