Тамбовская область находится в лесостепной природной зоне, которая характеризуется сравнительно низкой заболоченностью и сильным преобразованием естественных ландшафтов. В XX веке болота подверглись значительному антропогенному воздействию, что отразилось на флоре, но почти не было зафиксировано в публикациях последних трех десятилетий. Нами в 2011–2021 гг. маршрутно-ключевым методом обследовано 46 болот в 13 районах Тамбовской области, на основе полученных результатов составлен список высших растений, указано их распределение по основным типам болот (низинные, переходные, верховые) и встречаемость. На болотах Тамбовской области выявлено 158 видов сосудистых растений (108 родов и 55 семейств) и 33 вида мхов (14 родов и 9 семейств). Наиболее часто на болотах региона из сосудистых растений встречались Salix cinerea, Typha latifolia, Lysimachia vulgaris, L. thyrsiflora, Carex acuta, Betula pubescens, Calamagrostis canescens, Phragmites australis, Lycopus europaeus, из мхов – Sphagnum fallax, S. flexuosum, S. angustifolium. На болотах зафиксированы популяции 22 видов, включённых в Красную книгу Тамбовской области.   БлагодарностиРабота проведена в рамках выполнения государственного задания 121051100099-5.

In three wetlands in southeastern Ontario, ferric hydroxide was deposited on the roots of Typha latifolia (maximum, 67 × 103 ppm); in four other wetlands, deposition was negligible (< 103 ppm). Iron deposition was seasonal, with the peak period in July–August corresponding to peak biomass production of shoots. In one wetland where Carex rostrata and Phragmites australis occurred, seasonal plaque formation was similar. Plaque formation was not obviously related to Eh and pH regimes.

Abstract Anthropogenic activities can be the source of saline solid wastes that need to be treated to reduce their salt load to meet the purposes of reuse, valorization or storage. In this context, chloride remediation can be achieved using high-salt accumulating plants. However, there is very limited information on the comparative potential of different species in the same environment, and only scarce data concerning their efficiency as a function of growth stage. In order to rationalize these selection criteria, three macrophytes i.e. common reed (Phragmites australis), sea rush (Juncus maritimus) and cattail (Typha latifolia) were cultivated at two growth stages (6-months old and 1-year old) for 65 days in Cl- spiked substrates (from 0 up to 24 ‰ NaCl). The plants’ survival and potential capacity for removal of Cl- from substrates and accumulation in shoots were investigated. For the three studied species, mature and juvenile plants display a high tolerance to salinity. However, mature specimens with higher shoot biomass and Cl- contents are capable of greater chloride removal than juvenile plants. The sole exception is P. australis which displays just the same phytoremediation potential for both mature and juvenile specimens. Moreover, P. australis has the lowest potential when compared with other species, being 1.5 and 3 times lower than for J. maritimus and T. latifolia. When considering the plant growth and the shoot biomass production, chloride removal rates from the substrate point that mature J. maritimus should preferentially be used to design an operational chloride remediation system. The results highlight the relevance of considering the growth stage of plants used for Cl- removal.

Досліджено склад поверхневих ліпідів водних рослин Acorus calamus L., Typha latifolia L., Carex acuta L. при вирощуванні на концентрованому розчині нонілфенолу. Показано наявність суттєвих змін компонентного складу поверхневих ліпідів експериментальних рослин порівняно з контрольними. Виявлено зміни вмісту жирних кислот, що виявляються у зменшенні кількості вуглеводнів і порушенні процесу елонгації у біосинтезі окремих компонентів.

Phragmites australis, Typha latifolia, T. angustifolia and Arundo donax are tall wetland graminoids with the potential to replace fossil fuels under sustainable cultivation conditions. We investigated the biomethane (CH4) production of these four species, including four different genotypes of P. australis, which represent the high intraspecific diversity of European reed. All plants were grown under three different macronutrient supplies (no nutrients added, an equivalent of 75 kg N ha−1 year−1 added and an equivalent of 500 kg N ha−1 year−1 added). Biomethane production was measured in four independent batch digestion tests. Across all experiments, fertilization regime had little effect on CH4 yield, which was on average 222 ± 31 L kg−1 volatile solids (VS). The lowest yield was produced by T. angustifolia (140 L kgVS−1) receiving no nutrients, while the highest yield was produced by A. donax (305 L kgVS−1) in the highest nutrient treatment. The intraspecific diversity of P. australis did not affect biomethane production. All P. australis genotypes produced on average 226 ± 19 L CH4 kgVS−1, which, although high, was still lower than conventional biogas species. The biomass production of P. australis was less increased by fertilization than that of Typha sp. and A. donax, but all species had similar biomass without fertilization.
