a biophysical analysis of stem and root diameter variations in woody plants. | a comprehensive model of stem and root diameter variation was developed. the stem (or root) was represented using two coaxial cylinders corresponding with the mature xylem and the extensible tissues. the extensible tissues were assumed to behave as a single cell separated from the mature xylem by a virtual membrane. the mature xylem and the extensible tissues are able to dilate with temperature and grow. moreover, the extensible tissues are able to shrink and swell according to water flow intens ... | 2001 | 11351082 |

characterisation of phenolic compounds in wild fruits from northeastern portugal. | this study aimed to analyse the phenolic composition of wild fruits of arbutus unedo (strawberry-tree), prunus spinosa (blackthorn), rosa canina and rosa micrantha (wild roses). analyses were performed by hplc-dad-esi/ms. p spinosa fruits presented the highest concentration in phenolic acids (29.78 mg/100 g dry weight), being 3-o-caffeoylquinic acid the most abundant one, and flavone/ols (57.48 mg/100 g), among which quercetin3-o-rutinoside (15.63 mg/100 g) was the majority compound. (+)-catechi ... | 2013 | 23993541 |
bioactivity of different enriched phenolic extracts of wild fruits from northeastern portugal: a comparative study. | arbutus unedo, prunus spinosa, rosa micrantha and rosa canina are good sources of phenolic compounds, including anthocyanins. these compounds have potent antioxidant properties, which have been related to anticancer activity. herein, the in vitro antioxidant and antitumor properties of enriched phenolic extracts (non-anthocyanin phenolic compounds enriched extract- pe and anthocyanins enriched extract- ae) of the mentioned wild fruits were evaluated and compared. pe gave higher bioactive propert ... | 2014 | 24243401 |
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 |
carbon relations and competition between woody species in a central european hedgerow : i. photosynthetic characteristics. | the co2 uptake capacity of leaves of five competing woody species in an undisturbed developing central european hedgerow was investigated for possible factors determining competitive ability in the field. light-saturated maximal co2 uptake (a max) showed species-specific seasonal variations in prunus spinosa, a bushlike pioneer on fallow land, in crataegusxmacrocarpa and acer campestre, two treelike species dominating the canopy, in rubus corylifolius, a pioneer liane, and in ribes uva-crispa, a ... | 1984 | 28311448 |
characterization of selected wild mediterranean fruits and comparative efficacy as inhibitors of oxidative reactions in emulsified raw pork burger patties. | in the present study, water, ethanolic, and methanolic extracts from seven selected wild fruits originally from the mediterranean area, namely, strawberry tree ( arbutus unedo l., au), azarole ( crataegus azarolus l., ca), common hawthorn ( crataegus monogyna l., cm), blackthorn ( prunus spinosa l., ps), dog rose ( rosa canina l., rc), elm-leaf blackberry ( rubus ulmifolius schott, ru), and rowan ( sorbus aucuparia l., sa), were analyzed for the total amount and profile of phenolic compounds and ... | 2010 | 20681673 |
prunus spinosa fresh fruit juice: antioxidant activity in cell-free and cellular systems. | the antioxidant activity was assessed of fresh juice from prunus spinosa l. fruit (rosaceae) growing wild in urbino (central italy) by using different cell-free in vitro analytical methods: 5-lipoxygenase test, 1,1-diphenyl-2-picrylhydrazyl (dpph) free radical scavenging, and oxygen radical absorbance capacity (orac). trolox was used as the reference antioxidant compound. in the 5-lipoxygenase and dpph tests the fresh fruit juice of p. spinosa showed good antioxidant activity when compared with ... | 2009 | 20120103 |
an assessment of genetic variability and relationships among wild-grown blackthorn (prunus spinosa l.) plants based on rapd markers. | prunus spinosa, blackthorn, exists as wild populations that inhabit uncultivated uplands of coruh valley in the northeastern part of turkey; the fruit is used to make preserves. we examined genetic diversity in wild-grown prunus spinosa; 16 individual plants from wild populations of coruh valley were sampled and subjected to rapd (random amplified polymorphic dna) analysis. we tested 51 random decamer primers; 15 of them gave reproducible polymorphic patterns. these 15 primers produced 226 bands ... | 2009 | 19876864 |
pollination biology of fruit-bearing hedgerow plants and the role of flower-visiting insects in fruit-set. | in the uk, the flowers of fruit-bearing hedgerow plants provide a succession of pollen and nectar for flower-visiting insects for much of the year. the fruits of hedgerow plants are a source of winter food for frugivorous birds on farmland. it is unclear whether recent declines in pollinator populations are likely to threaten fruit-set and hence food supply for birds. the present study investigates the pollination biology of five common hedgerow plants: blackthorn (prunus spinosa), hawthorn (cra ... | 2009 | 19770165 |
traditional knowledge of wild edible plants used in the northwest of the iberian peninsula (spain and portugal): a comparative study. | we compare traditional knowledge and use of wild edible plants in six rural regions of the northwest of the iberian peninsula as follows: campoo, picos de europa, piloña, sanabria and caurel in spain and parque natural de montesinho in portugal. | 2007 | 17555572 |

the gathering and consumption of wild edible plants in the campoo (cantabria, spain). | this paper discusses the traditional consumption of wild edible plants in the rural communities of the campoo (cantabria), a region in northern spain. through semi-structured interviews with key informants, data on the perception, gathering, preparation and use of 60 edible wild plant species were collected. social, economic and cultural factors need to be taken into account when trying to understand why some wild foods and traditional vegetables continue to be consumed while others are not. wil ... | 2005 | 16503563 |
habitat and forage associations of a naturally colonising insect pollinator, the tree bumblebee bombus hypnorum. | bumblebees (bombus species) are major pollinators of commercial crops and wildflowers but factors affecting their abundance, including causes of recent population declines, remain unclear. investigating the ecology of species with expanding ranges provides a potentially powerful means of elucidating these factors. such species may also bring novel pollination services to their new ranges. we therefore investigated landscape-scale habitat use and foraging preferences of the tree bumblebee, b. hyp ... | 2014 | 25259579 |
trends in wild food plants uses in gorbeialdea (basque country). | despite wild food plants' potential nutritional and economic value, their knowledge and consumption is quickly decreasing throughout the world. we examine how the consideration that a wild plant use is within the cultural tradition of a given area relates to its consumption by analysing 1) current perception and 2) past and present use of six wild plants' food-uses, of which only three are locally perceived as being part of the local tradition. research was conducted in gorbeialdea, an area in t ... | 2017 | 28087368 |
traditional alcoholic beverages and their value in the local culture of the alta valle del reno, a mountain borderland between tuscany and emilia-romagna (italy). | traditional alcoholic beverages (tabs) have only received marginal attention from researchers and ethnobotanists so far, especially in italy. this work is focused on plant-based tabs in the alta valle del reno, a mountainous area on the border between tuscany and emilia-romagna regions. the aims of our study were to document local knowledge about tabs and to analyze and discuss the distribution of related knowledge within the investigated communities. | 2016 | 27333772 |
