The seed productivity of spruce in the plantations of Krasnoyarsk and the introduction of its explants into culture in vitro

Abstract

In the conducted study, Siberian spruce plantations in six districts of Krasnoyarsk were evaluated, which resulted in the discovery of a very low yield of female cones. In three districts, the formation of cones on spruce was not detected at all. In other areas, cones were formed with average seed productivity, but with very poor seed quality, most of which were affected by conobionts. The introduction of full-grain seeds of Siberian spruce into culture in vitro led to the formation of callus cultures. The authors note that the selection of donor trees with high yields is necessary for the induction of somatic embryogenesis. Thus, the key topic of the article is the problem of low yield and quality of Siberian spruce seeds in the conditions of Krasnoyarsk, as well as approaches to improve this situation by introducing full-grain seeds into culture in vitro.
