Vaganov E.A., Kuznetsova G.V., Svistova V.I., Kruglov V.B. Anatomy of Tree Rings in Siberian Pine Grafts // Forest Science (Lesovedenie). 2010. No 3. P. 59-70 (in Russian).

A detailed analysis of the peculiar anatomical structure of tree rings in graft components of different Siberian pine (Pinus sibirica Du Tour) climatypes is given. Tracheidograms for the variability of anatomical characteristics of tree rings formed in graft and rootstock stems in different years have been constructed. The dynamics of changes in radial sizes and cell wall thickness in the graft and rootstocks tree rings formed in the same years are considered. The interrelationships between the anatomic parameters of tree rings were found. They can be used for separating the impact of graft on rootstock and vice versa.
