Effect of Shade, Irrigation and Nutrients on Dry Matter Yield and Flavonoid Content of American Skullcap
American skullcap (Scutellaria lateriflora), a medicinal plant species valued for its sedative properties associated with flavonoids, is generally harvested from the wild. Information on how openExpand
The variability of terpenes in conifers under developmental and environmental stimuli
Systematizing the observed changes in terpene quantity and quality in the three most important forest-forming conifer genera of European temperate climate zone emphasizes a complex function of these interesting compounds in trees including interplant signaling in forest communities. Expand
Effect of Forest Biomass Pretreatment on Essential Oil Yield and Properties
Essential oils (EOs) are natural and economically valuable aromatic compounds obtained from a variety of crops and trees, including forest trees, which have different therapeutic and biologicalExpand
Metabolite profiling and molecular responses in a drought-tolerant savory, Satureja rechingeri exposed to water deficit
The study’s results provide the foundation for gene expression analysis of savory and other species of Lamiaceae as the effective application of drought stress before harvesting can increase the quantity and quality of raw material. Expand
Response of conifers to UV-B and climate in mountain areas
The present study was focused to examine the combined effects of climate and ultraviolet-B radiation on conifer tree-ring density. Statistical methods were employed to extract tree responses inExpand
The Effect of Snow on Plant Chemistry and Invertebrate Herbivory: Experimental Manipulations Along a Natural Snow Gradient
Changing snow conditions have strong effects on northern ecosystems, but these effects are rarely incorporated into ecosystem models and our perception of how the ecosystems will respond to a warmerExpand
A temporal analysis of antioxidative defense responses in the phloem of Picea abies after attack by Ips typographus.
A sequence of changes in the endogenous levels of antioxidant defense molecules in the bark beetle-affected Norway spruce showed consistency with the general ecophysiological stress-response concept, and provided important avenues for evaluating the role and effectiveness of antioxidants in systemic acquired resistance against the complex interactive effects of bark beetle attack and environmental factors.

Eff ects of artifi cial soil drought on Scots pine fruiting, seed vitality, and pollen germination
In spring 2003, an artifi cial soil drought was induced by roofs constructed below the crown canopy in a 60-year-old Scots pine (Pinus sylvestris L.) stand. Th e experiment included a randomizedExpand


Rethinking the role of many plant phenolics - protection from photodamage not herbivores?
It is suggested that patterns in phenolic levels, often used to support the concept of trade-off between growth and herbivore defence in relation to resource availability, may actually reflect different risks of photodamage. Expand

Beneficial effects of enhanced UV-B radiation under field conditions: improvement of needle water relations and survival capacity of Pinus pinea L. seedlings during the dry Mediterranean summer
The possible mechanism(s) by which supplemental UV-B radiation alleviates the adverse effects of summer drought in Mediterranean pines (Petropoulou et al. 1995) were investigated with seedlings ofExpand
Changes in biologically active ultraviolet radiation reaching the Earth's surface.
Satellite-based observations of atmospheric ozone and clouds are being used, together with models of atmospheric transmission, to provide global coverage and long-term estimates of surface UV-B radiation, and ground-based measurements show that summertime erythemal UV irradiances in the Southern Hemisphere exceed those at comparable latitudes of the Northern Hemisphere by up to 40%, whereas corresponding satellite-based estimates yield only 10-15% differences. Expand
Increased polar stratospheric ozone losses and delayed eventual recovery owing to increasing greenhouse-gas concentrations
The chemical reactions responsible for stratospheric ozone depletion are extremely sensitive to temperature. Greenhouse gases warm the Earth's surface but cool the stratosphere radiatively andExpand
Carbon/nutrient balance of boreal plants in relation to vertebrate herbivory
Fundamental differences between the response of woody plants and graminoids to vertebrate herbivory suggest that the dynamics of browsing systems and grazing systems are qualitatively different. Expand
Applied environmental stresses to enhance the levels of polyphenolics in leaves of hawthorn plants.
It is indicated that either water-deficit stress or cold stress treatments, or a combination of the two, can be used to enhance the levels of desired polyphenolics in the leaves of these two hawthorn species in a photobioreactor system. Expand
Differences in Host Use Efficiency of Larvae of a Generalist Moth, Operophtera brumata on Three Chemically Divergent Salix Species
Salicylates reduced the growth of the generalist winter moth mainly by feeding deterrence caused by 6-hydroxy-2-cyclohexenone and catechol and compared to the deleterious effects of salicylate the effects of other secondary compounds were minor. Expand
Differential accumulation of flavonoids and hydroxycinnamates in leaves of Ligustrum vulgare under excess light and drought stress.
It is hypothesized that flavonoids may serve antioxidant functions in response to excess light and drought stress, and that a coordinate control system between hydroxycinnamate and flavonoid pathways operated in L. vulgare exposed to excessLight. Expand
