Other claims from this paper (7)
- Intervention effect Germination energy of cottonwood seed decreased gradually as moisture stress rose from 0.0 to 10.0 atm.
- Intervention effect A moisture stress of 15.0 atm inhibited cottonwood germination except at 32 and 38 C.
- Intervention effect The reductive effect of 38 C on germination energy was particularly marked after seed storage.
- Intervention effect Only 15-atm moisture stress or 15 C greatly reduced total germination of cottonwood.
- Intervention effect Twelve months of storage reduced cottonwood germination under optimum conditions (27-32 C) from 90% to 69%.
- Intervention effect Little cottonwood seedling growth took place at moisture stresses above 5 atm and at temperatures of 15 and 38 C.
- Association Initial growth of cottonwood was related to seed size.
