| in vitro antioxidant activity of some selected prunus species in korea. | in the course of the investigations of natural antioxidants, we examined the antioxidant activities of the methanol (meoh) extracts of some selected prunus species, including p buergeriana, p davidiana, p padus, p pendula for. ascendens, p. sargentii, p. serrulata var. spontanea and p. yedoensis by three methods as represented by the 1,1-diphenyl-2-picrylhydrazyl (dpph) radical, total ros (reactive oxygen species) and the peroxynitrite (onoo-) scavenging activity tests. we also evaluated the act ... | 2002 | 12510840 |
| use of the relative concentration to evaluate a multimedia model for pahs in the absence of emission estimates. | with no confident emission information, a dynamic multimedia model (popsme) was evaluated by comparing predicted and measured relative concentrations (defined as the ratio of concentration in a medium to that in soil) for 12 polycyclic aromatic hydrocarbons (pahs) (phenanthrene, anthracene, fluoranthene, pyrene, chrysene, benz[a]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, dibenz[a,h]anthracene, benzo[g,h,i]perylene, and indeno[1,2,3-c,d]pyrene). field monitoring for m ... | 2004 | 14998022 |
| antioxidative and anticancer activity of extracts of cherry (prunus serrulata var. spontanea) blossoms. | organic solvent (methanol, ethanol, and acetone) extracts and water extracts of cherry (prunus serrulata var. spontanea) blossoms were prepared, and antioxidant activities of the extracts were evaluated. methanolic cbe (100 microg/ml) showed the highest total phenol content (104.30 microm), radical scavenging activity (34.2%), and reducing power (0.391). the effect of cbe on dna damage induced by h(2)o(2) in human leukocytes was evaluated by comet assay. all cbe was a potent dose dependent inhib ... | 2007 | 17577669 |
| 'kwanzan stunting' syndrome: detection and molecular characterization of an italian isolate of little cherry virus 1. | evident stunting was observed for the first time on prunus serrulata 'kwanzan' indicator trees in southern italy during the indexing of two sour cherry accessions from cultivars 'marasca di verona' and 'spanska'. bud break and shooting were delayed and the developing leaves remained small. during the third year many kwanzan plants died, regardless of the indexed cultivar. electrophoretic analysis showed the presence of dsrna pattern in extracts of stunted kwanzan with a similar size to that of v ... | 2009 | 19463722 |
| antioxidative and antiviral properties of flowering cherry fruits (prunus serrulata l. var. spontanea). | the phenolic compounds of many fruits have been known to be efficient cellular protective antioxidants. in this study, antioxidative and antiviral properties of flowering cherry cultivars (prunus yedoensis, prunus sargentii, prunus lannesiana, and prunus cerasus) in korea were investigated. the antioxidant property was assayed for specific activities including 2,2-diphenyl-1-picrylhydrazyl (dpph) hydroxy radical scavenging activity, reducing power capacity, and superoxide dismutase (sod) like ac ... | 2010 | 20821824 |
| transpiration of urban trees and its cooling effect in a high latitude city. | an important ecosystem service provided by urban trees is the cooling effect caused by their transpiration. the aim of this study was to quantify the magnitude of daytime and night-time transpiration of common urban tree species in a high latitude city (gothenburg, sweden), to analyse the influence of weather conditions and surface permeability on the tree transpiration, and to find out whether tree transpiration contributed to daytime or nocturnal cooling. stomatal conductance and leaf transpir ... | 2016 | 26048702 |
| measuring and modeling the variation in species-specific transpiration in temperate deciduous hardwoods. | we investigated which parameters required by the maestra model were most important in predicting leaf-area-based transpiration in 5-year-old trees of five deciduous hardwood species-yoshino cherry (prunus x yedoensis matsum.), red maple (acer rubrum l. 'autumn flame'), trident maple (acer buergeranum miq.), japanese flowering cherry (prunus serrulata lindl. 'kwanzan') and london plane-tree (platanus x acerifolia (ait.) willd.). transpiration estimated from sap flow measured by the heat balance m ... | 2008 | 18765372 |
| over-expression of the paap1 gene from sweet cherry (prunus avium l.) causes early flowering in arabidopsis thaliana. | a homologue of squamosa/apetala1, designated paap1, was isolated from prunus avium by reverse transcription-pcr (rt-pcr). the full length of paap1 cdna is 753 bp, and it codes for a polypeptide of 250 amino acid residues. sequence comparison revealed that paap1 belongs to the mads-box gene family. phylogenetic analysis indicated that paap1 shared the highest identity with squa/ap1 homologues from prunus serrulata. real-time fluorescence quantitative pcr analysis showed that paap1 was expressed a ... | 2013 | 23206932 |
