| 英文摘要 | To investigate how growth form and habitat origin affect phenotypic plasticity to resource supply in the tibetan alpine herbs, the phalanx-type species stipa capillacea and the guerilla-type species carex montis-everestii were sampled from two different habitats (alpine steppe and alpine scrubland) and grown under three levels of light intensity and two levels of nutrient supply. interspecific differences in light-induced plasticity were detected only in number of ramets, specific leaf area and leaf sheath length. plasticity in plant biomass, number of ramets and rhizome length in response to light intensity differed between the two habitats. stipa plants were more plastic than carex plants in number of ramets and specific leaf area in response to light intensity. carex plants from the alpine scrubland expressed greater light-induced plasticity in plant biomass and number of ramets than those from the alpine steppe, and stipa plants showed less interhabitat differences in plasticity, which may be closely related to their contrasting growth forms. clonal growth form and habitat origin affected nutrient-induced plasticity in none of the measured traits. it may be the guerilla growth form that makes carex plants more efficiently adapted to highly heterogeneous light conditions in scrubland, and less habitat-dependent plasticity contributes to success of the phalanx-type stipa plants in alpine habitats. the results are discussed in the context of foraging for heterogeneously distributed essential resources and adaptation to habitat origin.
