Abstract
Far Eastern forests are complicated by form and diverse by specific composition. The genus «Pinus» is widely represented among basic forest forming species. It includes two subgenuses: two coniferous and five coniferous pines. Native five coniferous pines of subsection Cembrae are generally represented in the South of the Far East: Korean pine and Dwarf pine. Transport domestication of southern part of the Far East territory, active anthropogenic activity led to reduction of forest areas which are occupied by five coniferous pines. It is necessary to take measures aimed at reforestation. In this regard are required seeds having high sowing qualities. Viability of five coniferous pines΄ seeds is underinvestigated. The aim of the investigation is to define sowing qualities (viability) of Korean and Dwarf pine׳s seeds, growing in southern part of the Far East. Investigation of seeds quality test was conducted with local seeds (nuts) of Korean and Dwarf pine which had been collected in forest stands of southern part of the Far East. Viability of seeds was defined according to the common methodology in forest seed farming. We used the solution of indigo carmine, which is dye the nonviable embryo of seeds. Viability of seeds turned out to be rather high: Korean pine from 91,0 to 95,8%, Dwarf pine from 91,2 to 91,7%. The degree of infection by harmful pests is absent. Pines seeds of the subgenus «five coniferous», collected in conditions of southern part of the Far East, are viable; they refer to the first class of quality and they are completely usable for reforestation of cedar Far Eastern forests.
