%X In order to study the flowering characteristics and breeding system of <em>Lonicera alberti</em>, we observed flower characteristics, floral dynamic and pollination insects in the field during the flowering period. We tested the pollen viability by TTC staining, MTT staining, benzidine &alpha;-naphthol staining and carmine acetate dyeing, and estimated its stigma receptivity by benzidine-hydrogen peroxide and diphenyl tetrazolium bromide staining methods. We studied the breeding system of <em>L.alberti</em> by the pollen-ovule ratio(P/O), the out-crossing index(OCI), and artificial pollination methods. There are two kinds of <em>L.alberti</em> flowers opening:corolla lobes blooming one by one and corolla lobes simultaneous blooming. The pollen viability reached the maximum at 6 hours after anthers shedding, and stigma receptivity was increased after bloom; Apis mellifera played an important role in the process of pollination. P/O was 583.43&plusmn;99.90 and the outcrossing index was 4. By artificial pollination testing, cross-pollination rate was 79.17%, and the self-fertility rate was 9.52%. The research suggested that the breeding system of <em>L.alberti</em> belonged to mixed mating system and cross pollination requires pollinators.
