Abstract:
Abstract The resource allocation of sexual plants at anthesis stage was first studied in a Primula nutans population in the alpine wetland of the east Qinghai-Tibetan Plateau. Using this plant species growing in the alpine wetland, some important questions were synthesized involved in the resource allocation and the significance of sizedependent effects was emphasized to explain the patterns of resource allocation. P. nutans of sexual reproduction allocated relatively few resources to underground (22.6%) and to reproductive organs (20.8%), and the aboveground allocation was about four times more than the underground allocation, which indicated that wetland plants of sexual reproduction had relative higher underground allocation of resources. The absolute and relative resources allocated to reproduction, stem and underground part of P. nutans were obviously sizedependent, and the absolute allocation to all organs and relative allocation to stems increased, but the relative allocation to reproduction and underground decreased with the increasing of individual size. The absolute resource allocation among reproduction, stem organs and underground part exhibited correlationgrowth regularity. There were tradeoff relations between reproduction and vegetation, reproduction and underground, and reproduction and stem in the resource allocation of P. nutans, but not between underground and stem. As organ resource allocation, the reproduction fitness of P. nutans also was sizedependent, implying that the bigger individual had more flowers to produce more seeds. Combined with the factors influencing the resource allocation, the sizedependent effects at the individual level provided a good explanation for the resource allocation of plant.
