Allelopathic activity of Elodea canadensis and Elodea nuttallii against epiphytes and phytoplankton
Elodea nuttallii and Elodea canadensis have both been introduced from North America to Europe. They are now common in many water bodies where they often form dominating stands. It was suggested that negative relationships between Elodea and phytoplankton or epiphytic covers exist, probably due to the release of growth inhibiting allelochemicals. This would be an effective strategy to avoid ligh...
متن کاملPhytotoxicity of four herbicides on Ceratophyllum demersum, Vallisneria natans and Elodea nuttallii.
The physiological effects of 4 herbicides (butachlor, quinclorac, bensulfuron-methyl and atrazine) on 3 submerged macrophytes (Ceratophyllum demersum, Vallisneria natans and Elodea nuttallii) were tested in laboratory. The variables of the relative growth rate and the photosynthetic pigment content showed that all of the tested herbicides affected the growth of the plants obviously, even at the...
متن کاملDistribution and morphological variations of invasive macrophytes Elodea nuttallii (Planch.) H. St. John and Elodea canadensis Michx in Croatia
The invasive species Elodea nuttallii was recorded for the fi rst time in the Croatian fl ora in 2006, in the drainage channels of Kopački rit (Baranja). After its establishment, E. nuttallii begins to spread to the eastern and northern part of the drainage channel network from 2006–2009. High water levels are responsible for the linear spreading direction of E. nuttallii, E. nuttallii and E. c...
متن کاملEffect of Elodea nuttallii Roots on Bacterial Communities and MMHg Proportion in a Hg Polluted Sediment
The objective of this study was to assess the effect of a rooted macrophyte Elodea nuttallii on rhizosphere bacterial communities in Hg contaminated sediments. Specimens of E. nuttallii were exposed to sediments from the Hg contaminated Babeni reservoir (Olt River, Romania) in our microcosm. Plants were allowed to grow for two months until they occupied the entirety of the sediments. Total Hg a...
متن کاملDo environmental factors influence composition of potential allelochemicals in the submersed freshwater macrophyte Elodea nuttallii (Hydrocharitaceae)?
Since Elodea nuttallii (Planch.) St. John was introduced to Europe from North America in 1939 it has invaded many water bodies and is widely spread over the continent. Its success is usually related to ease of adaptation to several environmental factors (DENDÈNE et al. 1993, JONES et al. 1993, OZIMEK et al. 1993, SIMPSON 1990). Our research, however, indicates that chemical defenses may play an...
