Actinorhizal Plant Nodulation and Nitrogen Fixation in Natural and Experimental Systems
… Frankia inoculum were applied as a root dip to Alnus glutinosa and Casuarina equisetifoloia seedlings. This treatment increased nodulation 5- to 10-fold in greenhouse experiments and also of A. glutinosa in a field experiment.

Dendrochronology and the study of crannogs.
… The dendrochronological potential of alder (Alnus glutinosa)was examined and a suitable methodology developed. Cross-correlation and chronology formation are possible but extreme ring-width values, i.e signature years, and compression of the outermost rings re identified as problematic …

Short Rotation Forestry and Earthworm Diversity: Impacts and Responses
… selection, growth and reproduction. The native Alnus glutinosa, Betula pendula and Fraxinus excelsior litter supported earthworms and their activities over non-native Acer pseudoplatanus, Castaneas sativa and Eucalyptus nitens. Native British earthworms indicated a significant preference (p < …

Seasonal and site relationships to acetylene reduction by actinorhizal black alder and Russian olive root nodules
… by root nodules of 4- to 8-year-old black alder (Alnus glutinosa (L.) Gaertn.) on an upland Alfisol and alder and Russian olive (Elaeagnus angustifolia L.) on a bottomland Mollisol increased exponentially with soil temperature. Soil moisture content, pH and nitrogen concentration and leaf nitrogen …

Managing symbiotically-fixed nitrogen on mined land for tree crops
… with four nitrogen-fixing species: black alder (Alnus glutinosa L. IGaertn.l), black locust (Robinia pseudoacacia L.}, bicolor lespedeza (Lespedeza bicolor) and autumn olive (Elaeagnus umbel/ata Thwnb.). Pitch x loblolly pine survival was good; however, eastern white pine survival was only fair, …

Studies on biological activities of Scottish plants.
… hisutanonol and oregonin were isolated from Alnus glutinosa. An acetophenone derivative paeonol from Alliaria petiolata, 3, 4-dihydroxycinnamic acid and 20-hydroxyecdysone were isolated from Centaurea amercana. The extracts of 48 species were tested in antimicrobial, antioxidant and general …

Holocene climate change and peatland dynamics in southern Sweden based on tree-ring analysis of subfossil wood from peat deposits
… from pine, oak (Quercus robur L.) and alder (Alnus glutinosa L.). Most of these RW chronologies were dated by radiocarbon (14C). An approach combining bog-tree RW, replication and mean-age data, with peat stratigraphic records was explored to provide information about local hydrology, …

Oxygen control of nitrogen fixation in Frankia and Coriaria arborea
… Myrica gale nodules is an air-filled pathway. In Alnus glutinosa, Casuarina cunninghamiana and Medicago sativa nodules the diffusion pathway has some “water-filled” or “solid” diffusion barrier. Speculation is offered on the location and functioning of fixed and variable diffusion resistance in …
