Mycorrhiza Formation in Pinus Sylvestris and Picea Obovata Seedlings in Forest Nurseries in Kazakhstan

This work presents research materials, the purpose of which is to grow seedlings of coniferous trees in the open field using artificial substrates of mycorrhizal macromycetes in forest nurseries of Central, North and Northeast Kazakhstan. The success of mycorrhiza formation in seedlings Pinus sylvestris and Picea obovata from forest nurseries of Akmola and Karaganda regions, and the survival rate of seedlings from forest nurseries of Akmola, Karaganda and Pavlodar regions of Kazakhstan are analysed. In the future, we want to expand the range of studied species and compare artificially mycorrhized seedlings with naturally mycorrhized species from natural forests. If we compare the survival rate of seedlings in nurseries, the highest in P. sylvestris seedlings in Shaldai is about 78%, low in Novodolenskoe, about 27%, and for P. obovata, on average, 66%. In the future, we want to expand the range of studied species and compare artificially mycorrhized seedlings with naturally mycorrhized species from natural forests.
