prunus padus (bird cherry) poisoning in cattle.		1996	8677622
phenological modifications in plants by various edaphic factors.	various mechanical, chemical and physical soil analyses were carried out, in addition to weather observations, for 3 years at several sites along an oceanic-continental gradient in a fjord district in western norway. all the environmental factors observed were correlated with the spring and a few late-season phenophases of many native and cultivated woody plants and some herbs by simple, linear correlations and by stepwise multiple and partial analyses. different techniques were used to try and ...	2001	11769320
screening seeds of scottish plants for antibacterial activity.	based on ethnopharmacological and taxonomic information, seeds of 21 scottish plant species from 14 different families were obtained from authentic seed suppliers. their n-hexane, dichloromethane and methanol extracts were assessed for antibacterial activity against 11 pathogenic bacterial species. methanol extracts of 11 plant species showed significant antibacterial activity. malva moschata and prunus padus were active against five bacterial species, reseda lutea against four, centaurium eryth ...	2002	12413709
decision making by generalist and specialist aphids with the same genotype.	one idea to explain the high incidence of specialisation in phytophagous insects is that their nervous systems are simple and unable to efficiently recognise multiple host plants. here this 'neural limitations' hypothesis is tested using a generalist (the summer winged virginopara) and specialist (the autumn gynopara) morph of a single clone of the black bean aphid, aphis fabae, that are almost identical morphologically and have the same genotype. electrical monitoring of stylet behaviour and no ...	2003	12837318
[morphological-ecological characters and growth patterns of main tree species leaves in urban forest of shenyang].	the study with statistic and multivariate analyses showed that the main meteorological factors affecting the growth and development rhythms of main tree species leaves in urban forest of shenyang were > or = 5 degrees c accumulated temperature, accumulated sunshine hours, and mean temperature in the middle ten days of each phenological period. the meteorological factors needed by the tree species varied with their phenological period. necessary low temperature and ci were required in germination ...	2006	17269315
screening seeds of some scottish plants for free radical scavenging activity.	from a consideration of ethnobotanical and taxonomic information, seeds of 45 scottish plant species encompassing 23 different families were obtained from authentic seed suppliers. the n-hexane, dichloromethane (dcm) and methanol (meoh) extracts were assessed, both qualitatively and quantitatively, for free radical scavenging activity in the dpph assay. the meoh extracts of 37 species exhibited low to high levels of free radical scavenging activity (rc50 values ranging from 2.00 to 4.7 x 10(-4) ...	2007	17357975
a comparison of phenological models of leaf bud burst and flowering of boreal trees using independent observations.	we compared and tested thermal time, sequential, parallel and flexible phenological models of leaf bud burst in birch (betula pendula roth. and b. pubescens ehrh.) and flowering in bird cherry (prunus padus l.) and rowan (sorbus aucuparia l.). we used phenological records from oulainen-ohineva (64 degrees 13' n, 24 degrees 53' e) in central finland from 1953 to 2002 to estimate model parameters. we tested the models with data collected in all but six years between 1896 and 2002 in southern and c ...	2008	19193570
in vitro screening for antioxidant, antimicrobial, and antidiabetic properties of some korean native plants on mt. halla, jeju island.	in this study, prunus padus, lonicera caerulea, berberis amurensis, and ribes maximowiczianum, which are mainly distributed on mt. halla, jeju island, have been investigated for their antioxidant, antimicrobial, and antidiabetic activities. the methanol extracts of r. maximowiczianum leaves and p. padus branches exhibited significant and dose-dependent antioxidant activity including electron-donation ability and reducing power. to analyze the antimicrobial activity, each extract was tested by a ...	2015	26997693
tree species composition affects the abundance of rowan (sorbus aucuparia l.) in urban forests in finland.	recent studies have shown a considerable increase in the abundance of rowan (sorbus aucuparia) saplings in urban forests in finland, yet the reasons for this increase are not well understood. here we investigated whether canopy cover or tree species composition, i.e., the basal areas of different tree species in norway spruce dominated urban forests, affects the abundances of rowan seedlings, saplings and trees. altogether 24 urban forest patches were investigated. we sampled the number of rowan ...	2015	25588119
forecasting plant phenology: evaluating the phenological models for betula pendula and padus racemosa spring phases, latvia.	a historical phenological record and meteorological data of the period 1960-2009 are used to analyse the ability of seven phenological models to predict leaf unfolding and beginning of flowering for two tree species-silver birch betula pendula and bird cherry padus racemosa-in latvia. model stability is estimated performing multiple model fitting runs using half of the data for model training and the other half for evaluation. correlation coefficient, mean absolute error and mean squared error a ...	2015	24789346
sex ratio and body mass of adult herbivorous beetles depend on time of occurrence and light conditions.	body mass and sex ratio (f/m) of folivorous insects are easily measured parameters that are commonly used to assess the effect of food quality, living conditions, and preferences on the selection of favourable sites for offspring. a study was conducted on the polyphagous beetle, gonioctenaquinquepunctata (a pest of the native prunus padus and alien p. serotina) and on the monophagous beetle, alticabrevicollis coryletorum (a pest of corylus avellana). both species have a similar life cycle with e ...	2015	26657564
effect of tree species on enzyme secretion by the shiitake medicinal mushroom, lentinus edodes (agaricomycetes).	we compared cold and hot wood extracts of 3 endemic siberian trees-namely, prunus padus (bird cherry), populus tremula (aspen), and betula sp. (birch)-on biomass production and laccase and peroxidase secretion in submerged cultures by the medicinal mushroom lentinus edodes. of the conditions tested, only hot prunus extracts stimulated biomass production, whereas all extracts stimulated laccase and peroxidase secretion, albeit to different extents. a large, differential stimulation of manganese p ...	2016	27649732
