Abstract:
In order to research the reproductive allocation strategy of Meconopsis integrifolia in response to altitude，the reproductive allocation traits of this species were studied at five different elevation plots，by using the field sampling investigation and laboratory drying and weighing methods.The results showed that individual size (aboveground biomass) and vegetative organ biomass reduced with the rising altitudes，however，there were significant increasing in reproductive organ biomass，stamen biomass，pistil biomass and reproductive allocation；individual size dependent reproductive allocation existed，namely，heavier individual size (aboveground biomass)，lower reproductive allocation；there were trade-off between vegetative organ biomass and reproductive organ biomass，between stamen biomass and pistil biomass at different altitudes.With the rising altitudes，the species invested more resources in reproductive organ and pistil，which could ensure the reproductive success in the harsh alpine habitats.
