| solid-phase microextraction of volatile components from natural grassland plants. | the volatile components from nine plants growing on natural grasslands in auvergne, central france, selected for the broad qualitative and quantitative diversity of their terpenoid fractions, were analyzed by high-resolution gas-phase chromatography and mass spectrometry (hrgc-ms) after static headspace solid-phase microextraction (shs-spme). shs-spme allowed all the plant material to be analyzed under the same conditions despite its wide-ranging composition. this is not always possible with oth ... | 2001 | 11170578 |

| key plant structural and allocation traits depend on relative age in the perennial herb pimpinella saxifraga. | perennial plant formations always include a mixture of various-aged individuals of community-creating species, but the physiological and competitive potentials of plants of differing age and the importance on whole community functioning are still not entirely known. the current study tested the hypothesis that ontogenetically old plants have limited biomass investments in leaves and enhanced foliage support costs. | 2005 | 15965271 |
| ploidy-specific interactions of three host plants with arbuscular mycorrhizal fungi: does genome copy number matter? | • premise of the study: polyploidy has been shown to affect different plant traits and modulate interactions between plants and other organisms, such as pollinators and herbivores. however, no information is available on whether it can also shape the functioning of mycorrhizal symbiosis. • methods: the mycorrhizal growth response was assessed for three angiosperms with intraspecific ploidy variation. different cytotypes of aster amellus, campanula gentilis, and pimpinella saxifraga were either l ... | 2010 | 21616819 |
