Abstract

The study presents an analysis of aging (falling) organs (leaves/needle-foliage) of Siberian spruce (Picea abies ssp. obovata (Ledeb.) Domin), downy birch (Betula pubescens Ehrh), lingonberry (Vaccinium vitis-idaea L.), mountain crowberry (Empetrum hermaphroditum Hager.), European blueberry (Vaccinium myrtillus L.), Schreber’s big red stem moss (Pleurozium schreberi (Brid.) Mitt.), Polytrichum spp., dwarf cornel (Chamaepericlymenum suecicum (L.) Aschers. & Graebn. (Cornus suecica L.)), and wavy hair-grass (Deschampsia flexuosa (L.) Trin.). We found a significant variation in the chemical composition (the content of lignin, phenolic compounds, tannins, nitrogen, and carbon, as well as the stoichiometric ratios “C/N,” “lignin/N,” “lignin/cellulose”) in different plant species of northern taiga forests. The supply of secondary metabolites with litter depended on the species composition of plant communities and the contribution of different plant species to the composition of the vegetation cover. The content of soluble tannins increased (p < 0.05) in spruce needle-foliage in an automorphic position in the landscape for Siberian spruce growing in different positions of the landscape of dwarf shrub-green moss spruce forests (automorphic, transit and accumulative landscapes), so intra-specific differences were found. Relationships between secondary metabolites, nitrogen and carbon have been studied in the aging photosynthetic organs of dominant various plant species in northern taiga spruce shrub-green moss forests.

俄罗斯科拉半岛矮灌木-绿苔云杉林植物中的酚类化合物、单宁酸、木质素、氮和碳之间的关系

摘要本研究分析了西伯利亚云杉（Picea abies ssp. obovata (Ledeb.) Domin）、绒毛桦（Betula pubescens Ehrh）、越橘（Vaccinium vitis-idaea L.）、山红莓（Empetrum hermaphroditum Hager.）、欧洲蓝莓（Vaccinium myrtillus L.）、施雷伯大红茎苔（Pleurozium）的衰老（脱落）器官（叶片/针叶）。）、山红莓（Empetrum hermaphroditum Hager.）、欧洲蓝莓（Vaccinium myrtillus L.）、Schreber's big red stem moss（Pleurozium schreberi (Brid.) Mitt.）、Polytrichum spp、矮山茱萸（Chamaepericlymenum suecicum (L.) Aschers.(Cornus suecica L.）和波浪毛草（Deschampsia flexuosa (L.) Trin.）。我们发现北部泰加森林不同植物物种的化学成分（木质素、酚类化合物、单宁、氮和碳的含量，以及化学计量比 "C/N"、"木质素/N"、"木质素/纤维素"）有很大差异。垃圾中次生代谢物的供应取决于植物群落的物种组成以及不同植物物种对植被组成的贡献。对于生长在矮灌木-绿苔云杉林不同景观位置（自动景观、过境景观和累积景观）的西伯利亚云杉来说，景观中处于自动景观位置的云杉针叶中可溶性单宁含量增加（p < 0.05），因此发现了特异性内部差异。研究了北泰加云杉灌木绿苔林中各种优势植物老化光合器官中次生代谢物、氮和碳之间的关系。
