Abstract:

To provide a basis for the reasonable utilization and protection of natural Prunella vulgaris L. resources, the current study was conducted to analyze the characteristics of reproductive allocation between sexual and asexual reproduction in P. vulgaris populations from heterogeneous environments. Multiple comparison and correlation analyses were carried out to understand the proportions of sexual and asexual reproduction of P. vulgaris in heterogeneous environments. The results showed that total biomass reached its maximum in the ripening period in heterogeneous environments. Each mode of biomass allocation among the different populations was sharp; the biomass allocation to spica and cloning changed dramatically, showing gradient differences with environment changes. The volume-weight, organic matter, water content and species diversity in heterogeneous environments played very important roles in the clonal growth process of P. vulgaris. The intensity of P. vulgaris reproductive allocation was different in different heterogeneous environments, which supports a trade-off relationship between sexual and asexual reproduction.
