The research was conducted to study the breeding system of Prunella vulgaris L. Flowering dynamics was observed. Pollen viability, stigma receptivity, pollen-ovule ratio (P/O), out-crossing index (OCI) were measured. Bagging experiments were conducted. The results showed that the life span of one single flower was 1-2 days, the flowering span for the inflorescence of stalk was 7-14 days, the P/O was 1 046+/-148. 26, the OCI was 2. Combined with results of bagging experiment, the breeding system of P. vulgaris L. was mixed with cross-polination and self pollination. In the absence of pollination insects, the pollination and fertilization can be accomplished with high seed setting rate, and the seeds have a relatively high germination rate.
