Helmisaari Enemies The Siberian silkworm reduces the growth in both height and diameter of L. gmelinii {Trees and Shrubs of the USSR 1956). 6. Larix sibirica Ledeb. Syn. Larix europaea var. sibirica Lonnd, Larix decidua var. rossica Henk et Horst, Larix decidua var. , L. sibirica var. russica Endl. Distribution L. sibirica is distributed over a range of 3000 km from west to east (Dylis 1981). In the east, its range borders that of Larix gmelinii, and in the west, that of Larix sukaczewii (Dylis 1981).

Found with Acer pseudoplatanus, Tilia tomentosa, Tilia petiolaris, Abies alba, Prunus spinosa, Larix polonica and Alnus viridis (Sokolov, Svyaseva&Kublyl977). Life history P. abies is a monoecious and anemophilous species (Sokolov, Svyaseva & Kubly 1977). Seed production starts at an age of 40-60 years in a closed canopy, and earlier in open conditions (Lagerberg & Sjors 1972). 0 g per 1000 seeds in central Europe (Sarvas 1964). Seeds are dispersed mainly by wind and partly by birds and animals (Sokolov, Svyaseva & Kubly 1977) during March and April in the year following flowering (Schmidt-Vogt 1977).

Gmelinii usually forms pure stands (Sokolov, Svyaseva & Kubly 1977), especially north of 66°N, where the tree layer is more discontinuous (Schotte 1917). Most stands are even-aged, with an age difference of approximately 20-40 years. A reason for this may be the absence of competitors during colonization in severe climates (Dementev 1959; Dylis 1961). On new alluvial soils, it is found together with Chosenia arbutifolia and Populus suaveolens, while on old as well as on lime soils and wet sites, it is associated with Picea obovata, Picea ajanensis, Abies sibirica, Abies nephrolepis and sometimes with Pinus sibirica.
