Other claims from this paper (18)
- Observation Outcrossing reproduction was observed in Rhodiola gannanica, with pollination mainly by wind.
- Observation Population flowering occurred in the season with abundant precipitation and high temperature.
- Observation Buds of Rhodiola gannanica appeared in early June.
- Observation Florescence of Rhodiola gannanica was in mid-June.
- Observation The flourishing florescence of Rhodiola gannanica was in early July.
- Observation The flowering duration of R. fastigiata was about 36 days.
- Observation Fruit ripening of Rhodiola gannanica began in late August.
- Association Bisexual plants flowered earlier than female plants.
- Observation The rate of flowering and fruiting of the community reached only 11.0%.
- Observation The 1-3 year old plants barely flowered and fruited.
- Observation 20.0%-25.1% of buds of female plants were damaged from bud to flowering stages.
- Observation 51.1%-65.0% of flowers were aborted from flowering to fruiting stages.
- Observation Only 10.1%-21.0% of ovules developed into seeds.
- Observation Seed production per female plant was 158.1.
- Observation Seed germination rate was 81.5% under artificial conditions.
- Observation Seedling survival rate reached 36.0% in the first year.
- Observation Seed quality was not the key ecological factor for reproductive success of Rhodiola gannanica.
- Mechanism Pollen limitation, low seed production and low seedling survival resulted in the reproductive success and endangered status of Rhodiola gannanica.
