| lipid peroxidation and superoxide dismutase activity in relation to photoinhibition induced by chilling in moderate light. | the effect of a chilling stress, at a moderate photon flux density for a few hours, on the peroxidation of membrane lipids and on superoxide dismutase (sod) activity was compared in leaf slices of chilling-sensitive and chilling-insensitive plants. the aim was to determine if susceptibility to chill-temperature photoinhibition could be related to either damage to membrane lipids by superoxide and-or a decrease in activity of chloroplast sod. plants used were nerium oleander l., grown at 45° c, a ... | 1991 | 24186344 |
| superoxide production by thylakoids during chilling and its implication in the susceptibility of plants to chilling-induced photoinhibition. | factors influencing the rate of superoxide (o 2 (-) ) production by thylakoids were investigated to determine if increased production of the radical was related to injury induced by chilling at a moderate photon flux density (pfd). plants used were spinacia oleracea l., cucumis sativus l. and nerium oleander l. grown at either 200° c or 45° c. superoxide production was determined by electron-spin-resonance spectroscopy of the (o 2 (-) )-dependent rate of oxidation of 2-ethyl-1-hydroxy-2,5,5-trim ... | 1991 | 24193624 |
| the effect of changing the composition of phosphatidylglycerol from thylakoid polar lipids of oleander and cucumber on the temperature of the transition related to chilling injury. | the composition and phase behavior of some lipid classes and mixtures of thylakoid polar lipids were measured to investigate their role as determinants of the temperature of the transition associated with chilling injury. for nerium oleander l., a plant which acclimates to growth temperature, a mixture of the phosphatidylglycerol (pg) and sulfoquinovosyldiacylglycerol (sqdg) showed transition temperatures of 22° and 10° c for plants grown at 45° and 20° c, respectively. this difference was simil ... | 1990 | 24196686 |
| flammability of some ornamental species in wildland-urban interfaces in southeastern france: laboratory assessment at particle level. | assessment of the flammability of ornamental vegetation (particularly hedges) planted around houses is necessary in light of the increasing urbanization of the wildland-urban interfaces (wuis) and the high fire occurrence in such areas. the structure and flammability of seven of the species most frequently planted as hedges in provence (southeastern france) were studied at particle level. spatial repartition of the different types of fuel particles within plants was assessed by means of the cube ... | 2013 | 23765042 |

| epidemiology of intoxication of domestic animals by plants in europe. | this review focuses on some of the most important poisonous plants in europe and provides an overview of the poisoning episodes that have occurred in european countries. poisoning of livestock and companion animals by plants is a relatively common occurrence. in europe livestock and horses are commonly poisoned by datura stramonium (jimson weed), senecio spp. (ragworts and groundsels), quercus spp. (oak), taxus baccata (european yew), nerium oleander (oleander), pteridium aquilinum (bracken fern ... | 2013 | 23570777 |
| unripe red fruits may be aposematic. | the unripe fruits of certain species are red. some of these species disperse their seeds by wind (nerium oleander, anabasis articulata), others by adhering to animals with their spines (emex spinosa) or prickles (hedysarum spinosissimum). certainly neither type uses red coloration as advertisement to attract the seed dispersing agents. fleshy-fruited species (rhamnus alaternus, rubus sanguineus and pistacia sp.), which disperse their seeds via frugivores, change fruit color from green to red whi ... | 2009 | 19847110 |
| copper, zinc and lead biogeochemistry in aquatic and land plants from the iberian pyrite belt (portugal) and north of morocco mining areas. | the ability of aquatic (juncus effusus l., scirpus holoschoenus l., thypha latifolia l. and juncus sp.) and land (cistus ladanifer l., erica andevalensis c.-r., nerium oleander l., isatis tinctoria l., rosmarinus officinalis l., cynodon dactylon l. and hordeum murinum l.) plants from portugal (aljustrel, lousal and são domingos) and morocco (tighza and zeida) mining areas to uptake, translocate and tolerate heavy metals (cu, zn and pb) was evaluated. the soils (rhizosphere) of the first mining a ... | 2015 | 25167810 |
