Other claims from this paper (11)
- Observation Seeds of Reaumuria trigyna could germinate in either light or darkness.
- Observation The optimal temperature for germination was 20-25 degrees C or 15/25 degrees C.
- Observation Germination rate reached 93% under the optimal temperature.
- Observation Seeds could start to germinate when soil moisture content was 2%.
- Intervention effect The germination rate was highest (89%) at 12% soil moisture content.
- Observation The optimal sand burial depth for seed germination was 1 cm.
- Observation No seed germinated when sand burial depth was greater than 5 cm.
- Intervention effect Sand burial depth had lesser effects on seedling mass than on emergence and height.
- Mechanism The high seed germination rate of Reaumuria trigyna enhanced the survival risk of its seedlings.
- Mechanism The high-germination seed character was one of the factors causing the species to be endangered.
- Observation Seeds of Reaumuria trigyna had high vigor and high germination rate.
