ARTIFICIAL MYCORIZATION OF SEEDLINGS OF PINUS SYLVESTRIS IN THE FOREST NURSERY OF MSI "AKKOL" FI

Abstract

This paper presents the materials of scientific research of a doctoral student, the purpose of which is to grow seedlings of coniferous plants in open ground using artificial substrates of mycorrhizal macromycetes in the Akkol forest nursery. The success of mycorrhiza formation in seedlings of Pinus sylvestris, as well as the survival rate of seedlings and the viability of growth, were analyzed. The materials presented in this text refer to 2018-2021 about 2500 seedlings of the studied species were collected and analyzed by a selective method over a period of four years. In the morphological analysis of the above-ground and underground parts of the seedlings of the studied species, mathematical, statistical and microscopic (with a magnification of 500 times) methods were used. Morphological analysis of 14 traits when comparing experimental and control variants in the nursery showed that the experience in most cases was superior to the control. In the future, I would like to expand the range of studied species and compare artificially mycorrhized seedlings with natural mycorrhized seeds in natural forests.
