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 significant effects on seedling emergence percentage and growth height.
Intervention effect Sand burial depth had lesser effects on seedling mass than on emergence and height.
Mechanism The high-germination seed character was one of the factors causing the species to be endangered.
