spatial distribution and management of isolated woody plants traditionally used as farmland boundary markers in ibaraki prefecture, japan.although noncrop woody plants in crop field landscapes serve multiple functions, the modernization of agriculture has threatened their preservation. in this study, isolated woody plants used as farmland boundary markers were investigated in ibaraki prefecture in the eastern kanto region. a total of 2001 individuals of 50 species were found around 177 equidistantly spaced points. the most frequently used species was deutzia crenata (60.7%), and the main subordinate species were pourthiaea villosa ...201223420389
dna damage in euonymus japonicus leaf cells caused by roadside pollution in beijing.the inhalable particles from vehicle exhaust can cause dna damage to exposed organisms. research on dna damage is primarily focused on the influence of specific pollutants on certain species or the effect of environmental pollution on human beings. to date, little research has quantitatively studied the relationship between roadside pollution and dna damage. based on an investigation of the roadside pollution in beijing, euonymus japonicus leaves of differing ages grown in heavily-polluted secti ...201627455298
dihydroagarofuranoid sesquiterpenes as acetylcholinesterase inhibitors from celastraceae plants: maytenus disticha and euonymus japonicus.natural cholinesterase inhibitors have been found in many biological sources. nine compounds with agarofuran (epoxyeudesmane) skeletons were isolated from seeds and aerial parts of maytenus disticha and euonymus japonicus. the identification and structural elucidation of compounds were based on spectroscopic data analyses. all compounds had inhibitory acetylcholinesterase (ache) activity. these natural compounds, which possessed mixed or uncompetitive mechanisms of inhibitory activity against ac ...201526545100

[ability of typical greenery shrubs of beijing to adsorb and arrest pm2.5 ].four typical types of green shrubs of beijing (euonymus japonicus, buxus microphylla, berberis thunbergii cv. atropurpurea, taxus cuspidate cv. nana) were selected to study their capacities in adsorbing and arresting pm2.5 using both field observations and air chamber simulations. concurrently, in order to analyze the pollution characteristics of beijing in winter and spring, the pm2.5 concentrations of december 2012 to may 2013 were collected. experimental results showed that: from the gas cham ...201425518685
effects of stomatal development on stomatal conductance and on stomatal limitation of photosynthesis in syringa oblata and euonymus japonicus thunb.during leaf development, the increase in stomatal conductance cannot meet photosynthetic demand for co2, thus leading to stomatal limitation of photosynthesis (ls). considering the crucial influences of stomatal development on stomatal conductance, we speculated whether stomatal development limits photosynthesis to some extent. to test this hypothesis, stomatal development, stomatal conductance and photosynthesis were carefully studied in both syringa oblata (normal greening species) and euonymu ...201425443830
measurement of partition coefficients for selected polycyclic aromatic hydrocarbons between isolated plant cuticles and water.partition coefficients between plant cuticles and water (kcutw) were measured for 10 selected polycyclic aromatic hydrocarbons (pahs) to evaluate the sorption capacity of plant cuticular layers for hydrophobic organic chemicals. the partitioning properties of pahs between cuticles and water were evaluated by using (1) isolated cuticular layers and (2) leaf homogenate. the abaxial and adaxial cuticular layers of euonymus japonicus were isolated by enzymatic digestion. a third-phase partitioning m ...201425038429
an endoparasitoid avoids hyperparasitism by manipulating immobile host herbivore to modify host plant morphology.many parasitic organisms have an ability to manipulate their hosts to increase their own fitness. in parasitoids, behavioral changes of mobile hosts to avoid or protect against predation and hyperparasitism have been intensively studied, but host manipulation by parasitoids associated with endophytic or immobile hosts has seldom been investigated. we examined the interactions between a gall inducer masakimyia pustulae (diptera: cecidomyiidae) and its parasitoids. this gall midge induces dimorphi ...201425033216

[coupling effect of two drought-resistant agents on photosynthetic characteristics of euonymus japonicus].a field study on the coupling effect of new drought-resistant agents fa handilong (fa hdl) and beijing green angel (bga) on the photosynthetic characteristics of euonymus japonicus showed that these two agents could all decrease the stomatal conductance (gs) and transpiration rate (tr) , and increase the net photosynthesis rate (pn) and pn/tr of e. japonicus leaves. the inhibitory effect of fa hdl on gs and tr was more significant when bga was not applied. fa hdl inhibited the pn and pn/tr when ...200717552185
[pahs in foliar dust from beijing urban area].a five-step sequential elution procedure with or without supersonic effect was tested for extraction of foliar dust from leaves of euonymus japonicus collected at two locations of beijing urban area. the samples were collected from either roadside or campus far away from any motor traffic. the foliar dust was characterized for size distribution, organic carbon content, and pahs content. it was found that majority of the foliar dust can be eluted in 4 min by distill water under supersonic effect ...200415202256
group feeding as a strategy for exploiting food resources in the burnet moth pryeria sinica.pryeria sinica (zygaenidae) larvae feed on young and growing leaves of euonymus japonicus in groups. the larvae often defoliate their host plant. hence, the larvae are occasionally subject to serious shortage in food resources. we hypothesize that larval aggregation is an adaptation for the economical utilization of limited food resources. to test this hypothesis, the patterns of resource utilization were studied on larvae settled on shoots of host plant in various group sizes. the amount of foo ...198228309896
penetration of iron and some organic substances through isolated cuticular membranes.cuticular membranes were isolated enzymically from tomato fruits and from the dorsal and ventral surfaces of the leaves of euonymus japonicus. penetration of fe from feso(4) and feeddha (ferric ethylenediamine di(o-hydroxyphenylacetate) in the absence and presence of urea through the isolated cuticular membranes was studied. fe from feso(4) penetrated more rapidly through the cuticles than fe from feeddha. urea reduced the penetration of fe from feso(4) and feeddha. binding of fe on the inner su ...196916657094
