RESULTS OF THE STUDY OF THE SIBERIAN TROUT LILY IN THE SIBERIAN REGION

The results of the long-term introduction study of the Siberian Trout Lily (Erythronium sibiricum) – a rare species for Siberian and Altai natural flora, were analyzed. The seasonal rhythm of the species is presented, with a short aboveground development (1.5–2.0 months), forced summer rest of underground organs (4.5–5.0 months) and a long winter rest (6.0–6.5 months). The age-related ontogenetic states of plants in the forest-steppe zone of Western Siberia were studied. For the first time, a rhizomatous-bulbous biomorph was presented in E. sibiricum with an annually renewed bulb and a long-term short rhizome. Ontomorphogenesis was described and it is established that during seed reproduction, the generative period in individuals begins in the sixth year. The results of the age status of individuals in the natural habitats of the Kemerovo, Tomsk, and Novosibirsk regions were obtained. The quantitative composition of biologically active and spare substances, ash content, nitrogen, phosphorus, and sulfur in leaves and bulbs was determined. It is noted that the bulbs are rich in starch (32.99–49.77 %) and saponins (9.87–15.11 %). The leaves are dominated by a high content of ascorbic acid 64.7–134 mg%, flavonols (2.1–2.6 %), sugars (25.1–43.7 %) and protopectins (3.4–4.8 %). For the first time, the content of nitrogen, phosphorus, sulfur and ash content in the leaves in the spring period was revealed and it was shown that there is an increase in the elements in the series: S < P < N < ash content. The variability of flowers’ shape and color in nature and culture was recorded.
