The article presents the results of testing and optimization of the sample preparation technique for fl ow cytometric analysis of two species that have not been previously studied in this aspect: Colchicum bulbocodium subsp. versicolor and C. laetum. We are using optimal LB01 buff er with added sodium thiosulfate, as internal standards we take Petroselinum crispum and Secale cereale. For the fi rst time, the DNA content in living samples of C. bulbocodium subsp. versicolor (2C = 8.049 pg) and C.

We assessed the features of natural pine regeneration in forests with diff erent ages of ground fi res in the Southern Urals depending on the level of heavy metal pollution.

The article presents studies of the influence of Amanita muscaria and Flammulina velutipes on the growth and development of seedlings of species of the Pinaceae family. The positive effect of mycorrhization by these fungi species on the growth and development of Picea abies and Abies sibirica was established. Thus, the presence of Flammulina velutipes and Amanita muscaria in the substrate accelerated the appearance of the first shoots by 4–8 days. Mycorrhization of Amanita muscaria influenced the morphometry of the seedlings of Picea abies and Abies sibirica.
