Germination ability is 0,12-0,29 %, the seed reproductions of second generation was obtained in 2015. The seeds are characterized by high parthenocarpy. The high level of empty seeds, the poor quality of endosperm and the lack of embryo are discovered on x-ray analysis.

The vitality of grafting by applying the pith on cambium with stock of Abies balsamea (L.) Mill. was reached to 81,8 %. So, the propagation is possible by all three methods: by seeds, cuttings and grafting. The problems remain: the low germination ability of seeds and the slow growth and development of young plants.
