| description | [Objective] The study aims to examine the breeding system, pollination characteristics, and endangered
mechanism of Rosa anemoniflora, and provide theoretical basis for the protection and breeding of
the rare and endangered plants. [Methods] Pollen viability was measured by in vitro culture germination
method. Stigma receptivity was measured by benzidine hydrogen peroxide method. Pollen morphology was
observed by scanning electron microscope. Flower characteristics, flowering dynamics, and visiting insects
were manually recorded and observed. [Results] (1) The pollen vitality of R. anemoniflora was the highest
on the fourth day of flowering, and the best period of stigma receptivity was the third day. (2) The
single flowering period of R. anemoniflora was 5-7 days, and the population flowering period was about
25 days. The hybridization index (OCI) was 4. The breeding system was heterozygous with partially selfcompatible,
and outbreeding requires pollinators. (3) R. anemoniflora had a single pollinator, with Apis
cerana and Bombus sp. being the main pollinators. [Conclusion] The breeding mechanism of R. anemoniflora
was heterozygous, partially self-compatible, and pollinated by insects. The single pollinating insect
and the susceptibility of pollination behavior to weather conditions and human interference were important
reasons for the endangerment of R. anemoniflora. Releasing effective insects during the flowering period
and reducing human damage were important measures for the conservation of R. anemoniflora. |
