Строение поглощающих корней у аборигенных и инвазивных древесных растений

Abstract

We compared the fine structure of the absorptive roots and mycorrhizal abundance between two invasive, Acer negundo and Amelanchier spicata, and two native, Acer platanoides and Sorbus aucuparia, woody plants belonging to the same family. The roots of invasive species were shown to be thicker: 304 ± 21 μm in diameter in Acer negundo vs 284 ± 15 μm in Acer platanoides and 273 ± 9 μm in Amelanchier spicata vs 241 ± 10 μmin Sorbus aucuparia. Mycorrhizal abundance, abundance of dark septate endophytes and root hairs did not differ between invasive and native species. Our findings only partly support the data obtained in previous studies.
